Climate Change

ハイライト 中国の鋼材需要の急増を受け、建築およびインフラプロジェクトが今年完了するにつれて上海鉄鋼先物が今月初めに5,200人民元/MT弱の史上高近くまで上昇したことから、銅価格はさらに上昇すると見込まれます（今週のチャート）。 銅は今年および来年にかけて実需ベースでの需給不足を記録し、在庫がさらに減少するとともに中国および世界的に銅スクラップの需要を押し上げるでしょう。 銅価格の上昇が続けば、現在の市場での口先介入が需要と価格上昇を抑えられない場合、中国の膨大な国家保有銅在庫（約200万MTと推定される）の一部を当局が放出する可能性があります。 強い鋼材マージンと製鉄所に対する新たな環境規制が高品位鉄鉱石（65% Fe）需要を押し上げており、同品は今週初めに約223ドル/MT弱の史上高を付けました。ベンチマークの鉄鉱石価格（62% Fe）は今週10年ぶり高値で取引され、約190ドル/MT手前でした。 当社は2021年12月の銅価格予想を4.50ドル/lbから5.00ドル/lbに引き上げます。さらに、本日の取引終了時に2022年物CME/COMEX銅をロングし、2023年物CME/COMEX銅をショートするポジションを取ります。より急峻なバックワーデーションを見込んでの取組みです。 特集 中国の唐山（Tangshan）製鉄拠点における汚染削減のための製鉄所稼働率の最大30%削減という政府指示は、建設およびインフラのブームに対応する既に逼迫した市場をさらに引き締めることになります（チャート2）。このブームは鋼材価格、そして結果的に鉄鉱石価格を急騰させました（チャート3）。過去と同様に、これが銅の強気相場の次の局面の舞台を整えます。 今週のチャート 鋼材の急騰が銅価格の更なる上昇を予告 鉄鋼の急騰は銅価格のさらなる上昇を示唆する 鉄鋼の急騰は銅価格のさらなる上昇を示唆する 当社のモデルでは、特に鉄筋（リバー）価格と銅価格の間に強い関係があることが今週のチャートで確認できます。鋼材は建築・インフラプロジェクトの前段階で使われ（鉄筋で補強されたコンクリートや圧延コイル製品など）、その後、完成したプロジェクトには銅が使われます（配線や配管の形で）。 チャート2 銅の強気相場は続く 銅の強気相場は続く 銅の強気相場は続く 建設・建築ブームに加え、製造業の継続的な回復が銅価格の追い風となり、2021年後半の世界的な活動回復がこれをさらに増幅します。チャート4は名目GDP水準と銅価格の関係を示しています。重要なのは、アジア（中国を含む）およびアジア以外の経済成長が銅価格とコインテグレーション（共積分）関係にあることで、すなわち経済成長と工業コモディティは長期的な均衡を共有しており、それが同時変動を説明します。 チャート3 鋼材ブームが鉄鉱石価格を押し上げる 鉄鋼ブームが鉄鉱石価格を押し上げる 鉄鋼ブームが鉄鉱石価格を押し上げる メディア報道はしばしば、中国の政府支出をGDP比で注目しがちです（例：社会融資総額のGDP比）。しかし商品価格動向を説明しようとする際に経済要因が除外されがちです。中国政府が民間部門（財・サービス面）をさらに拡大することに成功すれば、オーガニックな経済成長が中国のコモディティ需要を説明する上でより重要になります。 チャート4 世界経済の成長が銅価格を押し上げる 世界的な経済成長が銅価格を押し上げる 世界的な経済成長が銅価格を押し上げる 当社の銅モデルでは、名目中国GDP、新興アジア（EMアジア）GDPおよびアジア以外の新興国（EM）GDPに加え、鋼材と鉄鉱石価格が銅価格と共積分関係にあることが分かります。これは純粋な経済学的観点から期待される結果です。一方で、これらの工業用コモディティ価格と中国の名目GDPに対する社会融資総額の割合との間には共積分関係（経済的な共動性や共通トレンド）は見られません。これらのモデルにより、銅価格の説明や予測に役立たない偽の関係を回避できます。 チャート5 鉄鉱石・銅の需要はグリーン・エネルギーの整備で増加する 鉄鋼価格の急騰で銅が上昇 鉄鋼価格の急騰で銅が上昇 チャート6 再生可能エネルギーが新規増分発電を主導 銅、鉄鋼価格の急騰を受け上昇へ 銅、鉄鋼価格の急騰を受け上昇へ 長期的には、当社が過去の調査報告で指摘してきたように、分散型再生可能発電の導入、よりレジリエントな電力網、電気自動車（EV）への移行は、鉄鉱石や鋼材といったばら積み需要、および特に銅のようなベースメタルの需要成長の主要な源泉となります（チャート5）。1 すでに再生可能エネルギーは、世界の電力網に追加される新規増分発電の中で最も高い成長セグメントを占めています（チャート6）。 銅供給の増加にはより高い価格が必要 銅供給は短期（2022年末まで）では需要に対応するのが困難であり、再生可能エネルギーとEVの整備は大半がこれから始まる段階にあります。つまり中期（2025年末まで）および長期（2050年）において、需要を満たすためにはかなりの新供給を開発する必要があります。 短期的には、精錬銅の供給面、特に製錬所が半精製品として精製し製造入力にする凝縮物（コンデンセート）レベルが極めて低下しており、中国の製錬所におけるトリートメント料・精製料（TC/RC）の長期的な急落からも確認できます（チャート7）。先週およそ22ドル/MTで、これらの手数料は2013年に中国でのベンチマークTC/RC指数が開始されて以来の最低水準でした（reuters.comによる）。2 チャート7 供給減少で銅のTC/RCが低下、価格を押し上げる 銅のTCRCsが供給減で下落し、価格を押し上げる 銅のTCRCsが供給減で下落し、価格を押し上げる 銅の供給事情はチャート8にも表れており、年次の供給と需要を残高に換算すると、これが在庫市場を介して調整されます。国際銅研究グループ（ICSG）は、鉱山生産は昨年も前年並みで推移し、精銅供給はわずか1.5%の増加にとどまったと推定しています。 チャート8 実需の不足が銅在庫を引き下げる... 現物不足が銅在庫を取り崩す… 現物不足が銅在庫を取り崩す… ICSGの推定によれば消費は2.2%増加し、中国の保税倉庫在庫を調整後の今年の実需ベースの不足は456千MTが見込まれます。これで銅市場は4年連続の実需不足となり、2017年以降の平均不足は約414千MTです。その結果、在庫が再び供給ギャップを埋める頼みとなり、世界の在庫は前年比約25%減と低水準で今後も減少し続けるでしょう（チャート9）。 鉱業の設備投資が弱く、銅鉱石の品位が低下しているため、相当程度の新投資を促すにはより高い価格が必要です（チャート10）。しかし、これらプロジェクトのリードタイムは最良のケースでも5年であるため、鉱山会社は近い将来に最終投資判断を下してプロジェクトを承認する必要があります（チャート11）。 チャート9 ...結果として4年続く実需不足で在庫は低水準 …4年にわたる現物不足を経て低い …4年にわたる現物不足を経て低い チャート10 弱い投資と低下する鉱石品位を是正するにはより高い銅価格が必要 弱い設備投資と鉱石品位の低下を是正するには、銅価格のさらなる上昇が必要だ 弱い設備投資と鉱石品位の低下を是正するには、銅価格のさらなる上昇が必要だ チャート11 新規鉱山稼働までのリードタイムは短縮中だが時間は限られる 銅、鉄鋼価格の急騰で上昇へ 銅、鉄鋼価格の急騰で上昇へ 投資への含意 当社が銅に注目するのは、銅があらゆる再生可能技術に関わり、電気自動車（EV）にとっても重要であり、特にこの技術が広く普及した場合にその重要性が増すという単純な事実によります（チャート12）。 当社は短期・中期・長期の投資期間にわたり銅供給の課題が続くと予想しています。短期対応として、当社は2020年9月10日に2021年12月物銅をロングすることを推奨しており、このポジションは現在39.2%の含み益です。中長期をカバーするために、当社はS&P グローバル GSCI コモディティ・インデックスおよびiShares GSCI コモディティ ダイナミック ロール ストラテジー ETF（COMT）をそれぞれ2017年12月7日と2021年3月12日に推奨しており、これらは現時点でそれぞれ-2.3%および-0.8%となっています。 チャート12 電気自動車の普及が新たな銅需要を生む 鉄鋼価格の急騰で銅が上昇へ 鉄鋼価格の急騰で銅が上昇へ 本日の取引終了時に、上記の銅の需給ストーリーに基づく中期的な機会を捉えるために、2022年物CME/COMEX銅先物をロングし、2023年物CME/COMEX銅先物をショートするポジションを構築します。市場のさらなる引き締まりにより在庫が取り崩され、銅先物カーブのバックワーデーションがより急峻になると予想しています。 短期・中期・長期の当社ポジションに対する主なリスクは、世界的にCOVID-19パンデミックを抑制できないことであり、これは短期的なリスクだと考えています。第二のリスクは、中国国家備蓄局（別名：国家鉱物備蓄局）が保有する戦略的な銅コンセントレート備蓄の大規模放出です。後者のリスクに関して、同局の実際の保有量は不明ですが、約200万MTの範囲にあると考えられています。3 結論： 当社は工業用コモディティ、特に銅に対して強気の立場を維持します。 ロバート・P・ライアン チーフ・コモディティ＆エネルギー・ストラテジスト rryan@bcaresearch.com   コモディティ概要 エネルギー： 強気 米国エネルギー情報局（EIA）によれば、テキサス州は2022年末までに約10GWのユーティリティ規模の太陽光発電を追加する見込みです。テキサスは2020年に本格的に太陽光市場に参入し、2.5GWを導入しました。EIAは今後2年間で年平均約5GWを追加すると見ており、総太陽光容量は約15GW弱になる見込みです。この新規容量の約30%は米国で最も生産性の高い油田があるパーミアン盆地で建設される予定です。比較として、米国の太陽光発電の主要生産州であるカリフォルニアはEIAによれば3.2GWの新規太陽光容量を追加します（チャート13）。2022年末までに、新規太陽光発電の約3分の1がテキサスで追加される見込みで、同州はすでに国内で最大の風力発電地でもあります。風力の発電可能性は夜間に高く、太陽は昼間に最も豊富です。 貴金属： 強気 パラジウム価格は水曜日に約2,876ドル/ozで取引され、2020年2月の過去最高2,875.50ドル/ozを上回り3,000ドル/ozに迫っています。これは世界最大のパラジウム生産者であるロシアの金属メーカー、ノリリスクの生産見通し引き下げが続いているためです（チャート14）。同社は今週、以前の見通しを更新し、鉱山の浸水により銅・ニッケル・パラジウムの鉱山生産が今年最大20%減少する可能性があるとしました。パラジウムはガソリン車の触媒に使われ、世界がCOVID-19由来の需要破壊と自動車の供給を制限している半導体不足から回復するにつれて、自動車販売の回復が見込まれます。加えて、白金族金属（PGM）の生産は南アフリカの電力供給の不安定さにより妨げられており、国内の電力大手が需給調整のために計画停電を実施せざるを得ない状況です。当社は2020年4月23日にパラジウムのロングを推奨して以降、同金属のロングを維持しており、このポジションは35.6%の含み益です。

特別レポート

Dear client, Next week, in lieu of our weekly report, I will be hosting a webcast on Tuesday, March 30 at 9:00 am HKT and Tuesday, March 30 at 10:00 am EDT. In the webcast, I will share our outlook on China’s post-pandemic economic and policy dynamics. Best regards, Jing Sima, China Strategist   Highlights China is aiming for a massive adoption of new energy vehicles (NEVs) to help achieve its 2030 peak carbon dioxide emissions target. The country’s NEV share of total vehicle sales will likely rise significantly to 40% in 2030, from only 5.4% in 2020. This will translate into a compound annual growth rate (CAGR) of 24%-25% in Chinese NEV sales in this decade. China will become increasingly competitive and important in the global NEV supply chain. The country will maintain its leading position in global electric vehicle battery production while reducing its dependence on imported auto chips.   The Chinese NEV production/sales boom will likely reduce the country’s crude oil consumption while increasing the country’s copper demand during 2021-2030. It will also impact more positively on nickel and lithium demand than on cobalt demand. The Chinese NEV stocks could be a good long-term investment, but we recommend waiting for a better entry point. Feature China's production and sales of new energy vehicles (NEVs) have ranked first in the world for six consecutive years. The country’s NEV sales quadrupled during 2015-2020, propelled by supporting policies such as significant amounts of subsidies to buyers.  We believe China will continue to be the leader in both global NEV sales and production this decade. The country’s NEV production and sales will get supercharged by continuing favorable polices and increasing consumers’ interest in NEVs. Many market-driven factors, including falling NEV prices, longer driving range per charge, rapid expansion in the NEV charging/battery-swapping network, as well as new functions including autonomous driving and more software applications-based services, will accelerate NEV adoption in China during 2021-2030. According to the country’s NEV development roadmap, the NEV share of total vehicle sales in China aims to rise to at least 40% in 2030, from only 5.4% in 2020. This will likely translate to a compound annual growth rate (CAGR) of 24%-25% in Chinese NEV sales in this decade. In 2030, the NEV sales in units could be eight to nine times its 2020 level, rising from 1.37 million units to 12-13 million units (Chart 1). Benefiting from the massive scale of the domestic NEV market, China will become increasingly competitive and important in the global NEV supply chain. The country will maintain its leading position in global electric vehicle battery production while reducing its dependence on imported auto chips. The Chinese NEV production/sales boom will help reduce transportation fuel consumption, leading to less carbon dioxide emissions (Chart 2).  Chart 1Chinese NEV Sales: A Supercharged Decade Ahead Chart 2China: Booming NEV Sales Reduce Oil Demand, Leading To Less CO2 Emissions In addition, the country’s copper demand will likely be increase due to booming NEV production during 2021-2030. Meanwhile, the impact will be more positive on nickel and lithium demand than on cobalt demand. Given such  significant growth ahead for the Chinese NEV market, we believe Chinese NEV-related stocks are a potential good buy, but we recommend waiting for a better entry point.   China’s NEV Market: A Supercharged Decade Chinese NEV market is entering a supercharged decade (Box 1). Box 1 Our Forecast Of China’s NEV Sales In 2030 Our estimates of China’s NEV sales in 2030 were derived from two assumptions. First, we assume the NEV share of total Chinese automobile sales in 2030 to be 40%. Based on last October’s report, “Technology Roadmap 2.0 for Energy-Saving and New Energy Vehicles,” published by the China Society of Automotive Engineers (China-SAE), the China-SAE projects that NEVs will account for at least 40% of total automobile sales in China in 2030. The China-SAE is under the supervision of the Ministry of Industry and Information Technology (MIIT). Second, as car ownership – the share of households owning one car – has already risen to over 50% in China, we assume the CAGR of the country’s automobile sales will slow to 1.5%-2.5% in the next decade from 3.4% in the past decade. Based on this assumption, China’s automobile annual sales will likely increase to 29-32 million units in 2030. What Are The Underlying Drivers For Such Significant Growth? First, the interest in buying a NEV is rapidly growing in China. In a September 2020 survey done by Roland Berger, 80% of surveyed potential car buyers in China were considering buying an electric vehicle as their next car, the highest among major economies (Chart 3). Last year, this surveyed number for China was only 60%. We believe this shift in buying intention will continue and will consequently translate into a boom in NEV sales during 2021-2030. NEV battery costs have decreased by nearly 90% since 2010 and will continue to fall (Chart 4). This will drive down average NEV selling prices as the battery in general accounts 40-45% of the total production cost of NEVs, thereby making them more appealing to buyers. Chart 3China: Rising Interest In NEV Purchases Chart 4NEV Battery Costs Will Continue To Fall The average driving range per charge for NEVs will continue to rise. The average driving mileage per charge in China has nearly doubled, from 190km in 2016 to 360km in 2019.1 Currently, a growing proportion of NEV vehicles on the market can even achieve a mileage of 600km and above with a single charge. This is already comparable to traditional gasoline-powered vehicles, which can also cover approximately 600km per fuel tank.  More models with a wide range of selling prices will soon be on the market. Last June, the cheapest electric car with a selling price of only RMB 28,800 (about US$4,000) was released into the Chinese market. Since then the sales of this model have quickly surpassed the Tesla Model 3 to become the hottest seller in China. This shows consumer enthusiasm for affordable NEVs. In the meantime, the success of Tesla electric cars in China demonstrated Chinese consumers’ strong interest in high-quality and expensive NEVs. Chart 5China Has The Most NEV Models In The World Chart 5 shows that China is the country with most electric vehicle models in the world. The number of available electric vehicle models  was 227 in China in 2019, significantly higher than all other individual countries. According to McKinsey, more than 250 new battery electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV) models will be introduced in the next two years alone. Most of these models will likely be sold in China, adding more purchase options for Chinese consumers. Faster charging time for EV batteries as well as expanding charging/battery-swapping networks are in the making. This will greatly reduce recharge waiting time for NEV drivers. Chart 6Chinese NEV Charging Infrastructure: The Rapid Expansion Will Continue Based on the data from the China Electric Vehicle Charging Infrastructure Promotion Alliance (EVCIPA), the number of both public and private charging poles has increased significantly from 2015 to 2020. In addition,  the number of private ones has already exceeded the number of public ones each year since 2017 (Chart 6). The rapid expansion in the country’s charging station network will continue. The number of total charging poles will likely rise from 1.7 million units to the government’s target of 5 million units in 2025. In addition, Wood Mackenzie last May forecasted this number could reach 9.8 million units in 2030. Roland Berger last September reported that the number of charging locations per 100 km of roadway was about 6.1 in China, significantly higher than 2.2 in Germany and 0.5 in the US (Chart 7). In terms of the number of charging stations per 1000 NEVs, China has also significantly exceeded other major automobile producing countries (Chart 8). Chart 7The Number Of Charging Locations Per 100 km Of Roadway Is Higher In China Than In Many Other Countries… Chart 8…The Same Is True Of The Number Of Charging Stations Per 1,000 NEVs Meanwhile, the Chinese government is also promoting an expansion of battery-swapping networks. The Chinese auto manufacturer Nio has been the leader in this area. The company currently has a network of 178 battery-swapping stations located in and between major cities such as Beijing and Shenzhen; by the end of the year, it plans to have 500 stations. The battery-swapping time for the Nio EV now can be as fast as 90 seconds, even faster than fueling up with gasoline. EVs will become increasingly equipped with functions such as autonomous driving and more software applications-based services. EVs will also become more integrated with intelligent and interactive networks. All these features will make EVs more attractive to automobile buyers.  Second, with the 2030 target for peak emissions, the Chinese authorities will likely continue to develop favorable polices for the domestic NEV sector. China’s key policy support tools for NEVs include tax reductions, direct subsidies to manufacturers, consumer subsidies, and mandated government procurements. In the past, China has provided immense support for NEVs by spending billions of dollars on direct subsidies to manufacturers2 and on consumer subsidy programs.3 In the future, the country’s policy focus will be on NEV charging/battery-swapping network development as well as on NEV-related technology research and investment. For example, since 2019, auto manufacturers have received credits for each NEV produced. The credits take into consideration factors such as the type of vehicle, as well as its maximum speed, energy consumption, weight, and range. This measure will encourage NEV automakers to put more emphasis on technological change. These government supports of technology and network development, coupled with strong interest in NEV purchases by domestic consumers, should offset the impact of the government’s reduced direct subsidies for NEV production and sales. China has reduced overall direct subsidies to both NEV manufacturers and consumers, and vehicles must meet minimum technical and performance criteria to qualify. In 2021, subsidies will be reduced by 20% on NEVs for personal use, and by 10% on NEVs for public transport, including buses and taxis, from their respective 2020 level. In addition, NEV subsidies and tax exemptions will expire at the end of 2022 and subsidies will be limited to 2 million NEVs per year from 2020 to 2022. A vehicle price limit for passenger cars of CNY300,000 has also been introduced. The NEV subsidy level is currently less in China than in European countries as well as in the US, showing the Chinese NEV market’s diminishing dependence on subsidies. Bottom Line: The country’s NEV production and sales will get supercharged by continuing favorable polices and by increasing consumer interest in NEVs during 2021-2030. We expect China’s NEV sales to reach 12 to 13 million units in 2030, eight to nine times its 2020 level of 1.37 million units. Growing China’s Competitiveness In The Global NEV Supply Chain The global NEV market has two main subsectors – plug-in hybrid electric vehicles (PHEV) and battery electric vehicles (BEV). The former can be operated in either the electric-powered mode or internal-combustion engines (ICE) mode. The BEVs can only run in electric mode and are also called pure electric vehicles. Traditional ICE vehicle manufacturers from Europe, US, Japan, and South Korea have more competitive advantages in the global PHEV subsector supply chain due to their long-term dominance in the global traditional ICE vehicle market. Chart 9BEVs Account For Over 80% Of Chinese NEV Sales China has been putting more focus on the new BEV market as it has enabled a level playing field with traditional ICE vehicle players. Hence, China has stronger competitiveness in the global BEV subsector. BEVs account for approximately 82% of Chinese NEV sales (Chart 9). According to China-SAE, this ratio could reach 95% by 2035 as China will increase its development of the BEV market and the adoption of BEV vehicle options.   We expect China’s competitiveness will continue to grow along the global NEV supply chain, especially in the BEV subsector. Having the largest domestic NEV market in the world gives China the advantage of attracting NEV manufacturers and building a more integrated global supply chain. During 2017-2020, accumulated world NEV sales were about 8.8 million units, with the largest share of 49% coming from China, higher than 31% for Europe and 14% for the US (Chart 10).   China is the largest NEV battery producer in the global NEV supply chain. The battery is the most important component of a NEV, and its technological progress holds the key to transitioning away from fossil fuel dependence. Data shows that six out of the world’s top ten NEV battery producers are Chinese companies, together accounting for 41% of global battery sales in kwh last year (Chart 11). Chinese company CATL has been the largest NEV battery producer for the past four years. Chart 10China Has The Largest NEV Market In The World Chart 11Chinese Companies: Major Players In The Global NEV Battery Market The development of charging/battery-swapping infrastructure will continue to be faster in China than in other countries/regions due to the country’s much larger scale of EV users and related policy support. This allows China to collect more NEV charging-related data, which may be used to improve the country’s NEV manufacturing process, charging pole production, and the country’s charging infrastructure development.  The development of the 5G network is much more advanced in China than in any other countries. This allows NEV makers to work closely with IT/internet companies such as Huawei, Baidu, Tencent and Alibaba to test integrated applications such as the autonomous driving and AI functions of NEVs. This will help promote the technology advancement related to NEVs in all aspects in China. Chart 12Chinas NEV Net Exports Are Set To Go Up Due to its competitive advantages, China has become a net exporter of electric vehicles (Chart 12). In 2019, Chinese NEV sales abroad accounted for only 1.7% of the world total in US dollar terms, far below the US (31%), Germany (15%), and South Korea (9%). We expect growing competitiveness will allow China to gain share in global NEV exports. The area China needs to work on the most along the NEV supply chain is the design/manufacturing of automotive chips. There is still no Chinese company among the top ten global auto chip semiconductor companies based on sales revenue (Chart 13). Chart 13China’s Greatest Weaknesses Lie In Automotive Chip Design/Manufacturing Non-Chinese companies account for about 90% of the global auto chip supply while China contributes no more than 5%. The current automotive chip shortage has done much more severe damage to automakers in China than in any other country. Bloomberg recently reported the global auto industry might lose US$61 billion of 2021 sales from chip shortages, with 42% of the losses from China. In the recent National People’s Congress, the Chinese government reiterated the importance of addressing this weak link, with an urgency on reducing the country’s dependence on foreign auto chips. Bottom Line: China will become globally more competitive in the NEV supply chain. Impact On Commodity Markets The evolution in China’s NEV markets in this decade will have various impacts on commodities such as crude oil, copper, nickel, cobalt, and lithium. During 2021-2030, massive NEV adoption will only modestly reduce Chinese crude oil consumption for the transportation sector, while significant growth in NEV/charging pole/battery production will increase the country’s copper demand. Meanwhile, as NEV battery production requires raw materials including nickel, cobalt and lithium, rapid growth in NEV battery production will also have different impacts on these commodity markets.    Crude oil: In 2019, the total number of vehicles in China was 252.6 million units and the country’s total gasoline and diesel consumption was about 6,800 thousand barrels per day (kbpd) of crude oil equivalent. This equals 26.7 kbpd per 1000 vehicles. Annual NEV sales in China will rise from 1.37 million units in 2020 to about 12 million units in 2030. Assuming all these NEVs are only using their electric battery, this will cut oil consumption/imports by an increasing amount every year, ranging from 50 kbpd in 2021 to 320 kbpd in 2030. The reduction from increased NEV sales will have a relatively minuscule impact on China’s total crude oil imports. A 50-kbpd reduction in 2021 would account for less than half a percent of China’s 2020 crude oil imports. By 2030, this number could potentially rise to 1-3%, but is still insignificant. Copper: An average gasoline powered car uses only about 20kg of copper, while a hybrid car uses about 40 kg and a fully electric car uses roughly 80kg. In addition, NEV batteries and charging station chargers also require copper. Table 1 shows our rough calculation of the copper demand from the expansion of Chinese NEV market. Chinese copper demand may increase by 210 thousand tons in 2021 and by about 1,500 thousand tons in 2030. To put this into perspective, China consumed about 15 million tons of copper in 2020 based on World Bureau of Metal Statistics (WBMS) data. The increase in copper demand in 2021 is only 1.4% of 2020 copper consumption in China. However, when it increases to 1,500 thousand tons in 2030, it will account for 10% of China’s current copper consumption. Table 1China's Copper Demand Due To EV Adoption In 2021 And 2030 Chart 14Chinas NEV Boom Will Have A More Positive Impact On Nickel And Lithium Demand Than On Cobalt Demand Nickel: The NEV battery technology is on a trend to reduce the use of cobalt given its high price and limited supply, while increasing the use of nickel. This will be a long-term positive factor for nickel prices (Chart 14, top panel). Cobalt: EV battery makers are trying to reduce or even avoid the use of cobalt. In the next couple of years, the demand for cobalt will likely remain strong as the technology of non-cobalt batteries is still in the developing stage. Non-cobalt batteries in development include solid-state , lithium-sulphur, sodium-ion and lithium-air batteries. However, cobalt prices may face increasing headwinds in the longer term (Chart 14, middle panel). Lithium: Lithium is a very abundant mineral produced from either brines or hard rock sources, with products from clays also in the pipeline. There is no structural constraint on global lithium production. Lithium prices may remain elevated in the near term but as the supply catches up over a longer run, we expect lithium prices to go down (Chart 14, bottom panel). Bottom Line: The massive growth in the Chinese NEV market in this decade will have a small negative impact on crude oil demand and a more positive impact on commodity demand such as copper, nickel, cobalt, and lithium. However, cobalt may face a substitution risk due to its elevated prices while lithium may face the risk of increasing supply. Investment Implications On NEV-related Stocks Chart 15The Chinese NEV stocks: A Good Long-term Investment, But We Recommend Waiting For A Better Entry Point We believe share prices of the Chinese NEV makers and NEV battery producers will deliver considerable positive long-term returns. The basis for this assumption is that many of them will experience strong revenue growth over this decade.

Highlights Given that rising crop yields have been the main vehicle through which global supply of agricultural commodities grew to meet expanding demand, the risks posed to yields due to climate change are non-trivial. The impact of climate change will manifest itself in the form of two simultaneous trends: the gradual rise in temperatures alongside more frequent and severe weather events. While the latter will threaten immediate supply, the former is a slower moving process, and its net negative impact is unlikely to manifest before 2030. The implications of climate change on agriculture producers are non-uniform. Low-latitude countries with economies that are highly dependent on the agriculture sector will suffer most. Expect greater volatility in agriculture prices as the frequency of weather events will raise uncertainty. Feature The steady expansion of global population and rising per-capita calorie consumption has directly translated to growing demand for agricultural products of all types. However, these demand-side pressures increasingly will be met with disruptions to global supply of agricultural commodities, as the impact of climate change raises uncertainty. In any given year, the aggregate decisions of farmers all over the world – i.e., the choice of which crops to plant and how much acreage to dedicate to each crop – determine the supply and market prices of ags. In this competitive market, each farmer attempts to maximize his or her welfare by planting the crops that are expected to yield the greatest profit. Chart 12010/11 Shock Highlights Ag Vulnerability To Weather The collective action of these producers in reaction to perceived demand generally leads to stable prices, especially for staple commodities such as grains and oilseeds, which differ from industrial commodities in that they are not highly correlated with global business cycles. Demand trends are long-term and slow moving, and typically do not result in abrupt price pressures, as farmers have time to adjust and adapt to changing consumer preferences. Unforeseen, weather-induced supply-side shocks, therefore, are the main source of sudden price changes in ag markets. Such a shock was dramatically on display during the drought-induced crop failures in major grain and cereal producing regions in the most recent global food crisis of 2010/11. While this massive supply shock was not the first of its kind (Chart 1, on page 1), it highlighted the vulnerability of ag markets to weather risks and specifically the evolving environment under climate change. A 2019 study quantifies the impact of shifting weather patterns on the agricultural market, finding that year-to-year changes in climate factors during the growing season explain 20%-49% of change in corn, rice, soybean, and wheat yields, with climate extremes accounting for 18%-43% of this variation.1 In theory, the impact can manifest in several ways, sometimes contradictory: Extreme weather events: An increase in the frequency and intensity of droughts or floods which threaten to wipe out crops or reduce yields, creating unpredictable supply shocks. The gradual rise in temperature: Each crop has cardinal temperatures – defined by the minimum, maximum and optimum – that determine its boundaries for growth. Increases in temperatures induced by global warming may push the boundary, reducing yields in some regions. Changes in precipitation patterns: In many areas precipitation is projected to increase – both in short bursts and over longer periods. This will lead to greater soil erosion resulting in deterioration in the quality of soil. In other regions, precipitation will decrease, and drought is expected to become more frequent.2 Moreover, the interaction of these factors – along with other region-specific variables – will amplify the impact on crops: Rising temperatures and greater precipitation will result in greater amounts of water in the atmosphere, producing increased water vapor and greater cloud cover. This will reduce solar radiation, and will harm crop productivity. Elevated atmospheric carbon dioxide and CO2 fertilization: Greater CO2 concentrations brought on by continued growth in air pollution are positive for crops as they stimulate photosynthesis and plant growth. However, the impact differs across crops with plants such as soybeans, rice and wheat set to benefit relatively more than plants such as corn.3 Moreover, elevated atmospheric CO2 levels can help crops respond to environmental stresses and reduce yield losses due to ozone and crop water loss through partial stomatal closure and a reduction in ozone penetration into leaves. Temperature changes and the magnitude and intensity of precipitation impact soil moisture and surface runoff. Indirect effects of climate change – weeds, pests and pathogens – also present challenges as they require changes to management practices and may raise farming costs required. The impact of climate change on agriculture markets is already evident in increasing intensity and frequency of extreme weather events. The confluence of these factors, and the region- and crop-specific nature of these variables, makes it impossible to estimate the impact of evolving climate conditions on ag products with great accuracy. Nevertheless, our research suggests that the impact of climate change on ag markets will create opportunities in this evolving and highly uncertain market. Abrupt Shocks Amid Gradual Warming: The Long And Short View The impact of climate change on agriculture markets is already evident in the increasing intensity and frequency of extreme-weather events such as heatwaves, floods, and droughts. Charts 2A, 2B, and 2C, illustrate the impact of major weather events in crop-producing regions of the U.S. on yields, production and acreage for the crop year in which the events took place. Chart 2AExtreme Weather Events Reduce U.S. Corn Supplies … Chart 2B… Soybean Supplies … Chart 2C… And Wheat Supplies In A Big Way Chart 3Climate-Induced U.S. Supply Shocks Associated With Price Spikes   While the individual losses are a function of the magnitude of the event, the events highlighted translate to a 16%, 10%, and 7% decline in corn, soybean, and wheat yields, respectively. These supply disruptions generally do not extend beyond the event year, as the new crop year offers farmers a clean slate to raise output and maximize profits. Given that the U.S. is a major global supplier of these crops, extreme weather events and the subsequent supply reductions lead to non-negligible price pressures (Chart 3). While crop conditions thus far have failed to deteriorate in trend (Chart 4), greater frequency and intensity of weather events raise the probability of a decline in overall crop and could lower supply.   Chart 4Crop Conditions Have Generally Held Up Expanding the analysis to other major crop-producing regions of the world, we find that once again, extreme-weather events are associated with a decline in yields and production in the corresponding crop year (Chart 5). This exercise also indicates that the impact of droughts is significantly more pronounced than the impact of floods.4 While the weather-induced supply shocks described above are unpredictable, abrupt, and have an immediate impact on output and prices, the gradual warming of temperatures is a slow-moving process. Consequently, the impact will manifest in the form of gradual changes that are difficult to capture and quantify, especially given the mitigating effect of CO2 fertilization – i.e., higher yields resulting from higher CO2 in the atmosphere. Nonetheless, rising temperatures will become a serious risk in crop-planting regions both in the U.S. and globally (Chart 6). While rising temperatures are expected to bring about increasingly more wide-ranging supply disruptions (Chart 7), the net impact over the coming decade is not a clear negative. Chart 5Weather Events, Especially Droughts, Hurt Global Supplies Chart 6Rising Global Temperatures Will Pose A Serious Risk … Chart 7… Especially Above The 2°C Mark One study expects the positive impact of CO2 fertilization on yields to overwhelm the negative effect of rising temperatures over the coming decade (Table 1). Elsewhere, studies forecast different responses, with some predicting incremental yield gains over the coming decade before temperatures rise to levels that overwhelm the benefits of greater CO2. Similarly, according to the FAO’s assessment, the net negative impact of climate change on global crop yields will only become apparent with a high degree of certainty post-2030.5 Table 1Estimates For The Response Of Global Average Crop Yields To Warming And CO2 Changes Over The Next Decades Bottom Line: Given that rising crop yields have been the main vehicle through which global ag supply grew to meet expanding demand, the risks posed to yields due to climate change are non-trivial. Supply disruptions generally do not extend beyond the event year, as the new crop year offers farmers a clean slate to raise output and maximize profits. The impact will manifest itself in the form of two simultaneous trends: the gradual rise in temperatures alongside more frequent and severe weather events. While the latter will threaten immediate supply, the former is a slower moving process, and its net negative impact is unlikely to manifest before 2030. The Winners … And Losers Rising temperatures are expected to result in a negligible impact on ag markets over the coming decade; yet this finding is not uniform across all regions. The FAO study cited above finds that by 2030, the projected impact on crop yields will be slightly net negative in developing countries. However, in developed countries, the effect will be net positive. In terms of global supply, the impact of climate change over the coming decade is expected to remain relatively contained, affecting certain regions at various times without causing major global disruptions. That said, as global warming and extreme weather persist, the ramifications will begin to extend beyond individual regions, and will cause supply shocks on a global scale. In part, this can be explained by a greater potential for net reductions in crop yields in warmer, low-latitude areas and semi-arid regions of the world.6 This non-uniform impact will create relative winners and losers. Producers located in temperate regions – where climate change does not yet pose as serious a threat – are set to profit from their increased role in global supply. Conversely, tropical regions are much more vulnerable to climate change. This is especially true for those whose economies are highly dependent on agriculture (Chart 8). Chart 8Agricultural Economies In Tropical Regions Are Most Vulnerable On net, the overall economies of DM countries – which generally are not economically dependent on agriculture and are located in northern regions – will be relatively more insulated from the impact of climate change on the agriculture sector. Aside from the impact on producers, the implications on consumers are also region-dependent. Clearly the direct impact of climate change on global agriculture will be higher food prices, which directly impacts the food component of inflation generally. As a result, consumers who spend a large share of their income to food – generally consumers in lower income countries – will be hardest hit (Chart 9). Chart 9Higher Food Prices Disproportionately Hurt Consumers In Lower Income Countries In theory, a food supply shock is transitory, and given that food is usually excluded from core inflation gauges targeted by central banks, monetary policy should not react to these price spikes. All the same, aside from this direct impact on inflation, food inflation can also pass-through into other components of the CPI basket, for example through wage pressures or inflation expectations. This would lead to a more persistent impact on core inflation, forcing policy makers to react to these transitory forces, complicating the monetary policy response function for these countries. Given that inflation expectations are less well-anchored in lower income economies and that food makes up a larger share of consumption expenditures in these economies, they are most vulnerable to weather-induced food shocks. Chart 10Subsidies Partially Insulate Against International Shocks In countries where food prices are highly subsidized, the impact of higher global food prices will not immediately translate to higher domestic prices. This explains why there is no one-to-one relationship between global food prices and domestic food prices (Chart 10). Instead, the higher prices are absorbed by the governments, resulting in an expansion in government expenditures. This distorts the local food market, as it prevents demand from adjusting to the higher prices, and could potentially result in an undershoot in inventories that makes global markets even more vulnerable to further supply shocks. Bottom Line: The implications of climate change on ag producers are non-uniform. While higher-latitude regions are set to benefit, at least in the short-run, low-latitude countries with economies that are highly dependent on the agriculture sector will suffer most. On the consumer side, individuals who spend a large share of their income on food are set to suffer most. While consumers in countries that subsidize the crops will be protected from the immediate inflation risk, they may feel a delayed impact due to an increase in budget expenditures needed to cover the larger import bill. Mitigation Efforts While the potential impact of climate change on the agriculture sector can be large, it will be at least partially managed through adoption of mitigation policies (Diagram 1). Diagram 1Adaptation Reduces Vulnerability A key question in determining the extent of this behavior is whether warming temperatures and the increased occurrence and intensity of extreme events will be sufficient to justify a major acceleration of investment in agriculture. These efforts would range from simple management changes on the part of farmers to technological advances that raise the productivity of farming or reduce the vulnerability of farmers to climate change. For example, farmers across the U.S. have been planting corn and soybeans earlier in the spring, resulting in an advancement in planting dates (Chart 11). The earlier planting has also been accompanied by a longer growing season with the average number of days in the season increasing. Farmers are also adapting by altering their decisions on which crops to plant. For example, since soybean and corn are planted in many of the same regions of the U.S., farmers often plant more soybeans than corn when experiencing weather shocks. Chart 11Weather Events, Especially Droughts, Hurt Global Supplies The agriculture sector is also using more efficient machinery that can plant and harvest crops much faster as well as developing heartier seeds and more potent fertilizers. In turn, farmers will alter their decision making by selecting crop varieties or species that are more resistant to heat and drought. Or they will change fertilizer rates, amounts and timing of irrigation, along with other water-management techniques. Farmers also are making wider use of integrated pest and pathogen management techniques, in order to raise the effectiveness of pest, disease, and weed control. Given that the number of firms in the agriculture sector are fewer in developed markets than in the rest of the world, management decisions can be more easily implemented in the former. Farmers across the U.S. have been planting corn and soybeans earlier in the spring, resulting in an advancement in planting dates. On the other hand, emerging market countries where ag output is driven by numerous individual farmers will have a more difficult time implementing policies. Individual farms may not have the means to support themselves, which raises the potential impact of climate change. What is more, climate-change mitigation efforts may require projects, programs, or funds set aside by the government to support these efforts. This is more likely to occur in wealthier developed countries. Bottom Line: Adaptation and mitigation measures on the part of farmers have the potential to reduce the impact of climate change. That said, farmers in richer countries with the funds and institutions in place to support the ag sector likely will fare better. Investment Implications Over the coming decade, the ramifications of climate change are likely to be contained to a regional level. Although global supply will be vulnerable to regional disruptions, the impact will, in part, be mitigated by inventories, which have been rising for years. These stocks will create a buffer against unpredictable supply shocks (Chart 12). Chart 12Higher Inventories Needed To Buffer Against Unpredictable Shocks However, given that the global soybean market resembles an oligopoly with Brazil, the U.S., and Argentina accounting for 81% of global supply, global soybean prices will be more vulnerable to supply events in these regions than other crops (Chart 13). Chart 13Soybeans Most Vulnerable To Shocks Affecting Major Producers At the other end of the spectrum, global wheat markets will be relatively more insulated from isolated weather events impacting any one major producer as each of these regions contributes a relatively small share to global wheat output. This analysis also finds that yields and supply generally recover in the crop year following an extreme climate event. This implies that while the extent of damage from these events can be severe, they are not persistent unless the increasing frequency of extreme events leads to a secular change. Aside from the price impact, the weather and temperature changes will manifest in the form of greater volatility in supply, translating to greater price volatility. Options-implied volatilities for corn, wheat and soybeans have been on a general downtrend since the two major global food scares in 2007/08 and 2010/11 (Chart 14). We expect the trend to reverse going forward as the frequency of weather events will create greater price uncertainty. We summarize the findings of this report in Table 3 (Appendix, on page 16).

While rising CO2 causes C3 plants to raise the rate of photosynthesis and reduce the respiration rate, C4 plants do not experience a rise in photosynthesis since  photosynthesis is already saturated.

Highlights As an introduction to a series of BCA Special Reports on the investment consequences of climate change, we review the science around the subject and suggest a framework for analyzing its implications. The scientific consensus is that global warming is a reality and most likely human-induced. However, the uncertainty around the magnitude of the impact of climate change is large. The consequences of climate change are delayed, uncertain and global. But, for investors, the prudent course of action is to accept the scientific consensus – and the impact it will have on policymakers – and hedge or invest appropriately.  Feature Chart 1Climate Change Global Perception Bank of England Governor Mark Carney has called climate change “the tragedy of the horizon.” It is now perceived as a major threat across the globe (Chart 1). As such, it is essential to assess its macro and market consequences. In this introduction to our Climate Change Special Series, we review the existing literature and suggest a framework to assess the market relevance of this phenomenon. Going forward, we will produce a series of market-driven reports designed to help investors both mitigate the risk to their portfolios and identify opportunities arising from climate change. We intend to cover topics such as green financing, energy, and the geopolitical aspect of climate change, just to cite a few.  These reports will incorporate both quantitative and qualitative analysis to generate actionable investment recommendations. What Is Climate Change? Climate science is not new. The initial understanding of the effect of heat-trapping gases on global temperature dates back to Joseph Fourier’s early 1800s study of planetary temperature. Subsequent research showed the importance of the greenhouse effect, a phenomenon whereby greenhouse gas molecules (e.g. CO2, CH4, N2O) absorb infrared radiation emitted from Earth before reemitting it in all directions, including back to the Earth’s surface, thus making it harder for this energy to leave the planet. This excess of energy stored in the planet, above its normal energy balance, causes temperature increases. The distribution of environmental damages caused by global warming will not be uniform around the world. The rate of warming and other climate changes will differ across regions due to climate processes and feedbacks linked to local conditions.1 Regardless, up to 14% of the global population will experience above 2°C (3.6°F) warming – a level seen by scientists as a trigger for permanent damages and changes – even if the increase in global mean surface temperature (GMST) were limited to 2°C (3.6°F) by 2100 (CarbonBrief, 2018). The consequences of climate change are delayed, uncertain and global.  Even under the maximum policy effort scenario, studies assign 60% odds to an increase greater than 2°C (3.6°F) (Nordhaus, 2018). The longer policymakers, companies and investors delay tackling this issue, the less likely the world will stay below the 2°C threshold and the more rapid and abrupt the transition to a low-carbon economy will eventually be. A sudden transition will be more disruptive to the economy and damaging to investors. Defining The Issue: The Earth’s Atmosphere As A Global Common The Earth’s atmosphere - specifically its function as a sink for CO2 and other greenhouse gases (GHG) - falls within the problem of the global commons.2 It is a natural resource requiring global cooperation for its sustainable use and provision. Problematically, the consequences of climate change are delayed, uncertain and global.  Delayed because the burden of climate change policies mainly falls on current generations, whereas the benefits of lower climate damage accrue to future generations, leading every generation to think it can survive the issue and let the next generations handle it. Uncertain because the list of harms from climate change lengthens with the advance in climate-science studies. We learn more and more about the extent to which human activities are at fault and the extent of the damage that will befall the planet. Global because it does not matter whether the emissions take place in China, Europe, or the U.S. since GHG mix immediately once in the atmosphere. In that sense, it is a collective-action problem in which every country’s interest is to shift the abatement costs onto its neighbor. The global aspect is crucial. The optimal emission level of one country does not follow the global social optimal. Hence, every country has an incentive to emit as much GHG as possible now, before any consequences occur (Combes, 2016). What We Know So Far: Historical Data Both climate-alarmist and climate-denier groups have captured the public debate.This polarization clouds the underlying facts about current trends and the difference between what is unlikely, likely, or very likely to happen. The resulting lack of consensus will lead to over- or under-adaptation by the various economic agents, depending on their interests. FACT 1: GLOBAL WARMING IS A REALITY Anthropogenic Greenhouse Gas Emissions - Emissions of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) have risen steadily since the industrial revolution and at a brisk pace relative to the previous 12,000 years (Chart 2). Chart 2GHG Global Emissions Global Mean Surface Temperature - It rose by an estimated 1°C (1.8°F) from 1901 to 2016. According to NASA data, the 10 warmest years recorded in the past 139 years all occurred after 2005 (Chart 3). Chart 3Global Land And Ocean Temperature Global Mean Sea level - It has risen by an estimated 20.3cm (8 inches) since 1900 due to the expansion of waters and meltwater from shrinking ice sheets. Almost half of this rise happened in the last 25 years (Chart 4). Glacier and Ice Sheet - The melting of ice sheets will reduce the earth’s reflectivity, accelerating the warming process (Chart 5). The record low of sea ice extent in the Arctic and Antarctic was observed in 2012 and 2017, respectively. Chart 4Global Mean Sea Level Chart 5Glacier And Ice Sheet Precipitation - Historical changes in precipitation are much more volatile and region-specific than temperature and sea level changes. Moreover, there is a lack of data covering the period before 1951, which leads to low confidence in estimates of precipitation for this period and medium confidence post-1951. Annual average precipitation for global land areas increased slightly over the period 1901–2008, and the magnitude of observed changes varies across different datasets (Hartmann, 2013). Extreme Weather Events - These are defined, in a meteorological sense, as events at the “edges of the complete range of weather experienced in the past.” The frequency and severity of extreme weather events has been linked to global warming (Table 1) (Scott, 2016). Table 1Extreme Weather Events (1950 - Present) FACT 2: CLIMATE CHANGE IS HUMAN-INDUCED The Intergovernmental Panel on Climate Change (IPCC) – considered the world’s most authoritative scientific body on climate change – concluded in 2013 that the probability that global warming was human-induced was at least 95% (Table 2).  Table 2Evolution Of The Assessments Of Human Influence On Climate Change Chart 6Global Warming & Global GHG Emissions Since the late nineteenth century, GHG emissions – mainly CO2 – and global land and ocean mean temperature have shared a common steep upward trend (Chart 6). A recent study by Mann et al. estimates that in the absence of GHG emissions, the odds that 13 out of the 15 warmest years ever measured would all have happened in the current century are extremely small.3 More recently, a report by the National Academies of Sciences, Engineering, and Medicine (NASEM) concluded that “[I]n many cases, it is now possible to make and defend quantitative statements about the extent to which human-induced climate change has influenced either the magnitude or the probability of occurrence of specific types of events or event classes.”  According to most recent peer-reviewed studies, at least 97% of actively publishing climate scientists now accept human-caused climate warming (Cook, 2016). While science is not a matter of popular vote, this level of consensus among experts suggests that for investors the most prudent course of action is to accept the scientific consensus and hedge or invest appropriately. Projections & Assumptions Chart 7Global Emissions Projections Climate economics deals with conditional projections based on unknown probability distributions, implying a high level of uncertainty. The level of confidence around the nearer segments of the projections is relatively elevated. Conversely, at the far end of the projected period, by 2100 for most studies, the uncertainty increases drastically. According to the United Nations Environment Programs’ 2018 Emissions Gap report,  the 2°C (3.6°F) target drafted in the Paris Agreement in 2015 would require global emissions to be capped at 40 gigatons of CO2 equivalent by 2030. Throughout our Climate Change Special Series, we will rely on the following assumptions based on the IPCC Fifth Assessment Report (AR5) and the summary estimates from around 150 academic papers, the majority of which were published in 2018 (CarbonBrief, 2018).  Anthropogenic Greenhouse Gas Emissions - Global emissions rose in 2017 and are now ~14 GtCO2e above the required level by 2030. Current pledges are insufficient to meet the Paris Agreement’s long-term temperature goals (Chart 7). Key factors driving changes in anthropogenic GHG emissions are mainly economic and population growth. Projections of greenhouse gas emissions vary over a wide range, depending on both socio-economic development and climate policy – which are fundamentally uncertain. Climate economics deals with conditional projections based on unknown probability distributions, implying a high level of uncertainty. The majority of models indicate that scenarios meeting levels similar to RCP2.6 (a scenario that aims to keep global warming likely below 2°C (3.6°F) above pre-industrial temperatures) are characterized by substantial net negative emissions by 2100, on average 2 GtCO2e per year.   Chart 8Global Mean Surface Temperature Projections Global Mean Surface Temperature - Under all assessed emission scenarios, surface temperature is projected to rise over the twenty-first century. The change over the 2016-2035 period will be very similar to 1986-2005, and will likely be in the range of 0.3°C to 0.7°C (0.5°F to 1.3°F). Beyond that, the mean temperature rise across IPCC scenarios for 2046-65 and 2081-2100 is estimated to be 1.4°C (2.5°F) and 2.2°C (4°F), respectively (Chart 8). These estimates imply that there will be more frequent hot and fewer cold temperature extremes over most land areas on daily and seasonal timescales. Global Mean Sea Level - It has been established that the likelihood sea levels will rise in more than 95% of the ocean area is very high. Under all IPCC scenarios, the rate of sea level rise will very likely exceed the observed rate during 1971-2010. About 70% of the coastlines worldwide are in fact projected to experience sea level change within +/- 20% of the global mean. Precipitation - There are likely more land regions where the number of heavy precipitation events has increased than where it has decreased. Recent detection of increasing trends in extreme precipitation and discharge in some catchments implies greater risks of flooding at regional scale (medium confidence). These changes will not be uniform, with high latitudes and the equatorial Pacific more likely to experience an increase in annual mean precipitation while many mid-latitude and subtropical dry regions are likely to experience a decrease in mean precipitation. It remains a challenge to determine long-term trends in precipitation for the global oceans. Extreme Weather Events - Projections on extreme weather events can only infer the probability distribution of such events, i.e. more or less likely to happen. With a 1°C (1.8°F) additional warming, risks from extreme weather events are high (medium confidence from IPCC). More importantly, we can say with high confidence that these risks increase progressively with further warming.     Embracing Uncertainty The uncertainty around the magnitude of the impact of climate change is large. Yet, bounded uncertainty is informational. We can extract the following important, actionable conclusions: Projections for economic variables are relatively more uncertain than for geophysical variables. The link between GHG emissions and rising temperature is more certain than the level of emissions, output, and damages (Nordhaus, 2018).  Therefore, the largest uncertainty comes from economic growth and the level of emissions. We do not rely on estimates of global GDP impacts. On the other hand, it is easier to build scenarios for geophysical variables and obtain investment-relevant information from these projections. Simulating the path of future emission allows us to map this onto future temperature, sea level, and extreme weather variations. Economic models suggest that the higher the uncertainty, the larger the weights on low-probability/high-impact scenarios. This implies a positive risk premium due to risk aversion and favors stricter mitigation policies as insurance to shattering outcomes. As climate models are fine-tuned and continuously point to large damage uncertainty, the desired strength of policy could increase. Win-Win or “no-regrets” investments are the most likely at first.4 The Kaya Identity provides a simple framework to project future GHG emissions to visualize the uncertainty associated with different assumptions. The identity links future emissions to observable macroeconomic variables (see the Appendix for more details): F = P * (G/P) * (E/G) *(F/E) Where F denotes global CO2 emissions from human sources, P represents global population, G equals global GDP, and E is global energy consumption. The identity provides a useful framework for policymakers. To reduce emissions, there needs to be a reduction in one or more of the identity's components. Altering demographic trends and reducing global GDP per capita are very unlikely to happen given the damaging impact it could have – both for individuals and politicians’ careers!  At a global level, this leaves us with energy efficiency and carbon intensity of energy as the only key and viable options to reduce CO2 emissions.  Why Does It Matter To Investors? Markets are probably still underpricing climate-related risks because the effects only materialize gradually and in the long term – exceeding most investors’ investment horizon. Investors such as pension funds, insurers, wealth managers, and endowments need to be responsive to the threat posed by climate change. They typically have multi-decade time horizons, with portfolio exposure across the global economy. Their increasing interest in Environmental, Social, and Governance (ESG) measures fits well within this context.5 It reflects a need for more transparency and more stringent investing standards. Determining which firms or sectors will either win or lose the “green race” will be of the outmost importance to investors. Businesses are still navigating the financial and operational implications of climate change. To some extent, this can already be assessed based on the readiness of firms and sectors to adapt to a green economy – looking at the number of environmental technology patent applications, for example. Markets are probably still underpricing climate-related risks. The financing needed to mitigate climate change represents yet another opportunity for investors. Green bonds and sustainability-linked debt instruments are more widespread than ever. Sustainable debt issuance reached record levels last year, with a total of $260 billion issued, according to Bloomberg New Energy Finance data. Year-to-date issuance has nearly reached $180 billion.  Green bonds offer two main benefits to issuers:  corporate branding that sends a strong signal to the market of their commitment to climate change, and a wider investor base. Our series of market-driven reports are intended to both identify the risks and opportunities arising from climate change in order to help investors mitigating the risk to their portfolios. They will rely on the simple framework we present below. Climate Change Framework In future reports in our Climate Change Special Series, we will summarize our findings using a comprehensive analytical framework developed by Batten (2018) to assess the impact of climate change via physical and transition risks with respect to the type of shock induced by each type of risk. Physical Risks Physical risks are the most visible and immediate source of risk to investors and the financial sector. They can be defined as those risks that arise from the interaction between climate-related events and human and natural systems, including their ability to adapt— e.g. the volatility in food prices following a drought or a flood.6 An increase in climate-induced physical risks – such as heat waves, floods and storm – will have a direct effect on insurers. If these risks are uninsured, the deterioration of the balance sheets of affected households and corporations is likely to hurt the banking system. Electrical utilities, real estate and transportation infrastructure are other physical assets at risk of capital losses. Transition Risks Chart 9Public Opinion Of Policy Options To Tackle Climate Change Transition risks can be defined as the risks of economic dislocation and financial losses associated with the transition to a lower-carbon economy. Detrimental effects manifest themselves through three possible channels: Reduced production and consumption of high carbon products, especially energy produced using fossil fuels, potentially leading to stranded assets. Improvement in the energy efficiency of existing products and processes – energy intensity. Moving to low-carbon energy production – that is reducing carbon intensity. Lower energy intensity and carbon intensity, highlighted in the Kaya Identity above, can be achieved through technological innovation. The relationship between climate change and policy or regulatory framework is manifold, as policymakers will need both to respond to the consequences of climate change and to shape future GHG emissions. The primary responsibility for strategic planning rests with governments, which have a variety of policy options at their disposal (Chart 9).  Table 3 provides a useful template to link both physical and transition risks to the type of shocks they can induce, and importantly, how it can ultimately turn into financial and geopolitical risks. Table 3A Simple And Useful Template To Summarize Our Findings Climate change can impact demand (from investment, consumption or trade) or supply (labor, capital stock, technology or other inputs). For example, transition risks such as distortions from asymmetric climate policies across countries could directly impact trade or investment (FDI). This is what is commonly referred to as the pollution haven hypothesis, which states that more stringent environmental regulations induce polluting industries to relocate to countries with relatively lax environmental regulations. Ensuing reports in the Climate Change Special Series will include this template as a mean to summarize our findings. APPENDIX The Kaya Identity And Uncertainty Feedback Loop7 Diagram 1The Uncertainty Feedback Loop The Kaya Identity links observable macroeconomic and demographic variables to GHG emissions: CO2 = P * (Y / P) * (E / Y) * (CO2 / E) Where denotes P global population, Y global GDP, and E primary energy consumption.    It highlights the large degree of uncertainty around the macroeconomic impact on GHG emissions – especially at the end of the forecast period when additional uncertainty emanates from the feedback loop illustrated in Diagram 1. Historical Trend In CO2 Emissions From 1990 to 2014 CO2 emissions growth was 2.1% p.a.8: Global CO2 emissions during this period were pushed higher by population growth (1.3% p.a.) and rising rates of GDP per capita (1.9% p.a.). This was partly offset by declining energy intensity (-1.3% p.a.) (Chart 10). Chart 10Kaya Identity Components: Global Level The extent of the impact of these variables on CO2 emissions is region-specific. Therefore, when the identity is expressed at an aggregate and global level, it can lead to inaccuracies in long-term scenario analysis since it does not account for dependencies across the variables and does not differentiate between high population growth in countries with low vs. high GDP per capita growth, or between high GDP per capita growth from countries with high vs. low carbon intensity energy sources.  Using The Kaya Identity To Project Future GHG Emissions Population - The UN currently expect the population to grow by an average 0.4% p.a. through 2100 in its medium variant scenario. GDP per capita - The OECD projects GDP per capita will grow 2.2% p.a. between 2018 and 2060. Energy Intensity - We assume a 1.5% p.a. decline in energy intensity over the 2018-2100 period – the trend over the past decade. Carbon Intensity - In line with scenario B2 of the IPCC Special Report on Emissions Scenarios (SRES), we assume a 0.4% p.a. Combined, this leads to a 21% increase in CO2 emission by 2050, and a 63% increase by 2100. Accounting for other scenarios for each component results to a wide range of potential cumulative CO2 emissions; a median temperature between 2.6°C and 4.8°C by 2100 (Table 4). It is noteworthy that a rise in temperature above 2°C by 2100 is almost certain under all these scenarios. Table 4Scenarios Using The Kaya Identity Emission Reduction Possibilities Table 5Policy Approach Per Factor To reduce CO2 emissions, policies aimed at reducing the growth rate of one or more of the Kaya Identity’s components will be needed (Table 5). Assuming a constraint-free world, reducing average population and income growth rates to 0% from the projected 0.4% and 2.1% would reduce cumulative emission by 60% in 2100 vs. the baseline. Economic growth is the main driver of emissions growth. For instance, post-GFC, Europe’s emissions have been subdued due to poor economic growth. However, the constraints on these variables exist and are binding. These are not the area of focus to tackle climate change. Consequently, this leaves energy efficiency and carbon intensity of energy as the only viable options to reduce GHG emissions. In order to avoid breaching the 2°C target, the IPCC estimates CO2 concentration needs to be capped below 400 ppm by 2100. This can only be achieved by significant improvements to energy efficiency. Economic theory suggests that given that energy is a cost of production, energy efficiency will continue to improve. However, the required pace of reduction in energy intensity surpasses the incentive provided by the price mechanism. The externalities of an energy intensive economy are delayed and uncertain. Thus, these are not fully included in the cost-benefit analysis of investing in new technology. As a result, policies aimed at reducing the carbon intensity of global energy input will be an important source of CO2 reduction. This includes decreasing the carbon intensity of fossil fuels – e.g. switching coal to natural gas and developing carbon capture and storage technology – and reducing the share of fossil fuels in the energy mix – e.g. switching fossil fuel energy to renewables. We will expand on alternative sources of energy in a subsequent report. Importantly, the policy response should differ between regions. The drivers of emissions are heterogeneous and policies should fit the regional reality. The Kaya Identity can also be applied at the country or regional level. Chart 11The Kaya Identity Applied At The Country Level U.S. - Elevated income growth offset by increasing energy efficiency (Chart 11, panel 1). China - Robust income growth drove CO2 emissions higher (Chart 11, panel 2). Europe - Falling energy intensity and carbon intensity led to a decline in emissions (Chart 11, panel 3).

They have either no well-defined property right (no individual or nation has private control of their use) or lack an international enforcement mechanism to control their use (Edenhofer, 2015). The market failures associated with common pool resources (CPR) were popularized in Garret Hardin’s famous 1968 paper “Tragedy of the Commons”. 3 The likelihood is between 1 in 5,000 and 1 in 170,000 chances. 4 No-regret strategies are cost-effective under multiple climate change and policy response scenarios. Win-win actions provide beneficial externality while contributing to adaptation to various climate change scenarios. Under uncertainty, these strategies are the most likely to be implemented to begin the adaptation process rather than a riskier wait-and-see approach.
