Abstract:
China’s Global Energy Interconnection (GEI) initiative presents a transformational vision for meeting the world’s growing power demand with a globally interconnected electricity grid. The concept involves ultra-high-voltage transmission lines strung across vast distances and smart grid technology tapping large-scale renewable power sources. Chinese President Xi Jinping first touted GEI’s goal to “facilitate efforts to meet the global power demand with clean and green alternatives” at the UN General Assembly in 2015. The ambition of the GEI vision is enormous, especially since there is very little cross-border trade in electricity around the world today. Regional electricity integration initiatives championed by development banks and multilateral organizations have largely struggled against the formidable political, economic and technical complications that accompany interstate electricity trade. China has seen these challenges firsthand in its participation in the Asian Development Bank’s Greater Mekong Subregion electricity trade endeavor, which has progressed fitfully since the 1990s amid regional infrastructure gaps and uneven political support from member states. This report, prepared as part of the Belt and Road Initiative series published by Columbia University’s Center on Global Energy Policy, uses a case study of power trade in the Greater Mekong Subregion to assess the prospects for GEI in catalyzing energy integration around the world. It discusses why Greater Mekong Subregion integration has been slow, how GEI might help accelerate interconnection in the area, and what lessons the region offers for understanding the overall outlook for GEI. Based on this study, the author finds the following: Establishing a GEI-style global energy grid backbone by 2070 would require overcoming an extraordinary set of political challenges. The global grid outlined by GEI for the coming decades serves more as a demonstration of technical potential than a strict blueprint to be implemented. The limited scale attained thus far by the Greater Mekong Subregion project for grid integration and cross-border electricity trading demonstrates the headwinds such multinational efforts can face. Weak internal power sector development in recent decades has left some member states without the generation surpluses and robust power grids necessary to support meaningful levels of trade. In addition, power trade requires a strong degree of interstate political trust, motivated engagement by national utilities, and support from civil society players for the specific generation and transmission projects involved. Integration backers have historically struggled to build consensus across this diverse array of stakeholders. While enormous generation and transmission infrastructure projects are core components of the GEI vision and dovetail with the interests of China’s domestic proponents, considerable debate persists about their merits for fostering the renewables transition. Ultra-high-voltage transmission, a specialty of Chinese utilities, is a particular flashpoint. State interest in cross-border trade has been increasing across many regions in recent years, and more gradual gains in power trade around the world that can aid the renewable transition and bolster regional solidarity are possible. China can contribute greatly to this process: as an investor and contractor in grid projects abroad, as a member state of integration initiatives in Asia, and as an advocate of grid integration in international fora. GEI’s ultimate impact will depend in part on how advocates within China reconcile tensions between strengthening cross-border power trade and promoting domestic priorities, such as advancing the country’s own industrial policy objectives.

Abstract:
At least 1.5 million electric vehicle (EV) chargers have now been installed in homes, businesses, parking garages, shopping centers and other locations around the world. The number of EV chargers is projected to grow rapidly as the electric vehicle stock grows in the years ahead. The EV charging industry is a highly dynamic sector with a wide range of approaches. The industry is emerging from infancy as electrification, mobility-as-a-service and vehicle autonomy interact to produce far-reaching changes in transportation. This report compares EV charging in the world’s two largest electric vehicle markets -- China and the United States – examining policies, technologies and business models. The report is based on more than 50 interviews with industry participants and a review of the Chinese- and English-language literature. Findings include: 1. The EV charging industries in China and the United States are developing largely independently of the other. There is little overlap among the key players in the EV charging industries in each country. 2. The policy frameworks with respect to EV charging in each country differ. The Chinese central government promotes the development of EV charging networks as a matter of national policy. It sets targets, provides funding and mandates standards. Many provincial and local governments also promote EV charging. The United States federal government plays a modest role in EV charging. Several state governments play active roles. 3. EV charging technologies in China and the US are broadly similar. In both countries, cords and plugs are the overwhelmingly dominant technology for charging electric vehicles. (Battery swapping and wireless charging have at most a minor presence.) China has one nationwide EV fast-charging standard, known as China GB/T. The US has three EV fast charging standards: CHAdeMO, SAE Combo and Tesla. 4. In both China and the United States, many types of businesses have begun to offer EV charging services, with a range of overlapping business models and approaches. A growing number of partnerships are emerging, involving independent charging companies, auto manufacturers, utilities, municipalities and others. The role of utility-owned public chargers is larger in China, especially along major long-distance driving corridors. The role of automaker EV charging networks is larger in the United States. 5. Stakeholders in each country could learn from the other. US policymakers could learn from the Chinese government’s multiyear planning with respect EV charging infrastructure, as well as China’s investment in data collection on EV charging. Chinese policymakers could learn from the United States with respect to siting of public EV chargers, as well as US demand response programs. Both countries could learn from the other with respect to EV business models. As the demand for EV charging grows in the years ahead, continued study of the similarities and differences between approaches in China and the United States can help policymakers, businesses and other stakeholders in both countries and around the world.

3. Interactions between a Federal Carbon Tax and Other Climate Policies

Abstract:
Putting a price on carbon is a critical part of a low-cost strategy for reducing greenhouse gas (GHG) emissions, and a national carbon tax is a rare example of a climate change policy that has found bipartisan support in the United States. In 2018, legislation establishing a carbon tax was proposed by Democrats, Republicans, and bipartisan groups of US congressmen. However, while passing a carbon tax would certainly prove a significant step toward slashing emissions, simply adding a carbon tax to current policies is unlikely to achieve an emissions target at the lowest cost. Designing a carbon tax that contributes to achieving greenhouse gas reduction targets effectively and efficiently will require an examination of whether other new policies are also needed and whether existing policies can or should be changed or eliminated. With more proposals expected in 2019, such an examination is critical to ensuring both sufficient emissions reductions and an efficient set of policies that keep costs in check for taxpayers. As part of a broader carbon tax research program at the School of International and Public Affairs Center on Global Energy Policy at Columbia University, we have developed a framework for considering the interactions between a federal carbon tax and other policies that influence greenhouse gas emissions. Toward the goal of helping to design better policies, we identify policies and programs that are “complementary” to a carbon tax or “redundant.” A policy is defined as complementary if it: enables more cost-effective reductions of carbon dioxide emissions than a carbon tax would achieve on its own; or reduces GHG emissions and achieves a separate policy objective more cost-effectively than a federal carbon tax would on its own. Conversely, a policy is defined as redundant with a federal carbon tax if it leads to additional costs to society without achieving additional emissions reduction. In developing this framework, we recognize that real-world policies often do not fall cleanly into either category and that neither specifying the framework nor making the categorizations is an exact science. It is often difficult to identify a policy’s objective or evaluate its cost-effectiveness. In addition, the extent to which a policy complements a carbon tax depends on the nature of the carbon tax. Most obviously, with a lower carbon tax rate, fewer emission reductions would be achieved, and additional policies may be needed to make up the difference between the outcome and a science-based emissions reduction target. The results of the work, highlighted in the following table, indicate a relatively large number of policies can complement a carbon tax, such as those that support innovation in low-carbon technologies, tackle behavioral barriers to more efficient energy use, or improve public infrastructure and address barriers to reducing emissions unrelated to the price-related barriers addressed by a carbon tax. Conversely, the paper identifies regulations that force entities that pay the carbon tax to take specific actions to reduce their emissions, such as Environmental Protection Agency regulations of stationary sources of carbon dioxide emissions under section 111 of the Clean Air Act, as redundant with the carbon tax. The paper does not recommend which policies should be eliminated, changed, or added but intends to provide policy makers with information that will help them make these decisions.

4. Engaging State-Owned Enterprises in Climate Action

Abstract:
Policy makers, academics, and others have devoted significant effort over the past three decades to considering how best to incentivize households and private companies to reduce their greenhouse gas (GHG) emissions. There has been much less discussion about how best to incentivize state-owned enterprises (SOEs) -- companies that are either wholly or majority owned by a government -- to cut emissions. Yet when it comes to energy sector GHGs, these state companies are among the world’s leading emitters. They are major emitters at both the country and global levels, notably from electricity generation. In the aggregate, they emit over 6.2 gigatonnes of carbon dioxide equivalent per year in energy sector GHGs, which is more than every country except China. Public sector companies are also major providers of low-carbon alternatives, such as renewables and nuclear power, and importantly, they often operate under incentives that are quite different from those facing their private sector counterparts. Given the emissions profile of SOEs, the nature of their corporate mandates, and their ownership structure, Columbia University’s Center on Global Energy Policy undertook research to examine how best to engage these companies in efforts to lower greenhouse gas emissions as part of its ongoing work on climate change. The paper explores the role of these public sector companies in climate change, examines the effectiveness of market-oriented solutions such as carbon taxes in changing SOE behavior, and evaluates some other potential strategies for reducing their emissions. In short, the paper finds the following: The state-ownership structure of SOEs allows governments to exercise shareholder power to press for the implementation of their climate policy preferences. Providing public sector financing and making associated infrastructure improvements are other ways that a government can encourage its SOEs to invest in low-carbon alternatives. In contrast, many SOEs operate with nonfinancial mandates, market protections, and other conditions that limit their responsiveness to carbon pricing mechanisms that are effective in changing private sector behavior. There are other ways to alter public sector companies so that they embrace a greener pathway without being directed, especially if a firm’s management determines the pathway will serve its corporate interests. This can be especially important for state-owned companies that have the political weight to resist government climate policy pressures. In emerging economies with large SOE emissions and with governments willingly direct their SOEs, using these companies to reduce emissions is a policy tactic that can present implementation and other advantages because it requires the government to target a limited number of companies that the state already owns and controls. How much a government prioritizes climate change relative to other goals is the most critical factor that will determine the extent to which its SOEs prioritize low-carbon investments. Successfully merging climate goals into growth objectives, at both the broader economic and the SOE-company levels, increases the likelihood that a state company will engage in the low-carbon transition in a sustained manner.

5. 2019 Guide to Chinese Climate Policy

Center on Global Energy Policy
Abstract:
In 2018, China was the world’s leading emitter of heat-trapping gases by a wide margin. Its policies for limiting emissions will have a significant impact on the global climate for decades to come. From a historical perspective, China’s status as the world’s leading emitter is relatively recent. During most of the 19th and 20th centuries, Chinese emissions were modest. Then, in the early part of this century, as the Chinese economy boomed, Chinese emissions began to skyrocket, overtaking those from the United States around 2006. China’s cumulative emissions of carbon dioxide since the beginning of the Industrial Revolution are roughly half those from the United States. (Carbon dioxide, the leading heat-trapping gas, stays in the atmosphere for many years once emitted.) China’s leaders have declared that the impacts of climate change “pose a huge challenge to the survival and development of the human race” and that China is “one of the most vulnerable countries to the adverse impacts of climate change.”[11] The Chinese government has adopted short- and medium-term goals for limiting emissions of heat-trapping gases and a wide-ranging set of policies that contribute to meeting those goals. Those policies are shaped in part by other objectives, including promoting economic growth, cutting local air pollution and developing strategic industries. This Guide examines Chinese climate change policies. It starts with a review of Chinese emissions. It then explores the impacts of climate change in China and provides a short history of the country’s climate policies. The bulk of the Guide discusses China’s principal climate policies, explaining the policy tools the Chinese government uses to address climate change and related topics. Appendices provide background on institutions that shape climate policy in China. What are “climate policies”? Monetary and fiscal policies affect emissions and could therefore qualify, as could policies on many other topics. This Guide does not catalog all policies that could affect emissions or the climate, but instead focuses on policies most directly related to climate change, including those on energy, transportation, urbanization, forestry, climate adaptation and climate diplomacy. In choosing policies to focus on, I am guided in part by international convention and in part by governments’ extensive reporting on this topic. The Intended Nationally Determined Contributions submitted by more than 160 nations to the UN Framework Convention on Climate Change show a broad international consensus that policies on energy, transportation, urbanization and forestry, among others, are considered “climate policies.” The Chinese government’s official documents on climate change show the same.[12] Several official documents are important resources for anyone interested in China’s climate policies. Every year the National Development and Reform Commission (NDRC) publishes a report on China’s Policies and Actions for Addressing Climate Change.[13] These reports provide detailed information on a range of topics. Other key sources for understanding China’s climate policies include: China’s Intended Nationally Determined Contributions, submitted to the UN Framework Convention on Climate Change in June 2015;[14] Work Plan for Controlling Greenhouse Gas Emissions in the 13th Five-Year Plan, issued by the State Council in October 2016;[15] China’s First Biennial Update Report on Climate Change, submitted to the UN Framework Convention on Climate Change in December 2016;[16] China’s Second Biennial Update Report on Climate Change, submitted to the UN Framework Convention on Climate Change in December 2018;[17] and China’s Third National Communication on Climate Change, submitted to the UN Framework Convention on Climate Change in December 2018[18] Several themes run through these documents, including strong commitments to low-carbon development, cutting coal use, scaling up clean energy sources, promoting sustainable urbanization and participating actively in climate diplomacy. Implementation is fundamental to any policy. This is especially true in China, where policy implementation can be a considerable challenge. Key ministries may fail to coordinate. Resources for enforcement may be lacking. Policies designed to achieve different objectives may conflict. The priorities of provincial leaders may not align with policies from Beijing. For these reasons and more, stated policies—while important—are just part of the picture when it comes to understanding the Chinese response to climate change. The organization of this Guide reflects that. Most chapters start with a section of background facts. This background provides context and can help in forming judgments on the impacts of policies to date and potential impacts of policies in the years ahead. Where implementation has been especially challenging or successful, that is highlighted. This Guide can be read in parts or as a whole. Individual chapters are designed to stand alone and provide readers with information on discrete topics. The Guide as a whole is designed to provide an understanding of China’s response to climate change and the implications of that response for China and the world. The Guide can be accessed in three ways: by purchasing it as a book on Amazon.com by visiting the Guide to Chinese Climate Policy website at https://chineseclimatepolicy.energypolicy.columbia.edu/, and by downloading it for free from the website above or the website of Columbia University’s Center on Global Energy Policy—http://energypolicy.columbia.edu/ This is a “living document.” Many of the facts and policies it describes will change in the months and years ahead. As that happens, this Guide will be updated. New editions of the Guide will be released regularly.

6. China-Pakistan Economic Corridor Power Projects: Insights into Environmental and Debt Sustainability

Center on Global Energy Policy
Abstract:
Pakistan is increasing its use of coal to generate electricity at a time when many other countries are reducing coal use in order to cut greenhouse gas emissions or pollution. China is helping Pakistan expand its coal-fired generation capacity through the financing and construction of coal power plants as part of the China-Pakistan Economic Corridor (CPEC). CPEC is a component of Chinese president Xi Jinping’s Belt and Road Initiative (BRI), which aims to forge greater global connectivity in part through infrastructure development. Nearly 75 percent of the generation capacity of CPEC power plants is coal-fired. Pakistan’s National Electric Power Regulatory Authority (NEPRA) expects that CPEC coal power plants will be largely responsible for the projected increase in the country’s coal-fired generation capacity from 3 percent as of June 30, 2017 (fewer than six months after the first CPEC coal plant began commercial operation), to 20 percent in 2025. As part of its series on the Belt and Road Initiative, Columbia University’s Center on Global Energy Policy initiated research into the CPEC power sector projects, which account for the majority of the cost of CPEC projects. This paper examines two of the key concerns critics have about the BRI: environmental sustainability and debt sustainability. Concerns about environmental sustainability center on the ways in which an expansion of the amount of electricity generated globally by fossil fuels, especially coal, will increase greenhouse gas emissions, making it more difficult if not impossible to meet the emissions targets in the Paris Agreement. Concerns about debt sustainability focus on whether China’s lending in support of infrastructure projects will lead to problematic increases in debt, with some analysts maintaining that Beijing is intentionally seeking to push countries into debt distress in an attempt to gain control over strategic assets or decision-making in borrowing countries. The main findings of this study are threefold. First, the heavy focus on coal in the new generation capacity added by the CPEC power projects stems from both “pull” factors from Pakistan and “push” factors from China: The CPEC coal power projects reflect Pakistan’s long-standing goal of diversifying its generation mix away from fuel oil toward domestic coal in an attempt to decrease generation costs and conserve foreign exchange. They also reflect the perception of the administration of former prime minister Nawaz Sharif, whose pledge to end power outages helped his party win the 2013 election, that coal was the best option to bring on a large amount of new capacity in the short term. Although Pakistan has vast renewable energy potential, solar and wind power were considered too expensive and difficult to integrate into electric grids. Meanwhile, Chinese companies had several reasons to sell coal power plants to Pakistan, including exporting rather than warehousing excess power generation equipment, financial incentives provided by Beijing and Islamabad, and the ability to execute projects fast enough to help Sharif eradicate the blackouts hurting Pakistan’s economy before he stood for reelection in 2018. Second, there is a mismatch between the dominance of coal in the CPEC power generation mix and Beijing’s recent emphasis on green development as an important feature of the BRI. This gap between Beijing’s rhetoric and the reality on the ground can be explained in large part by Pakistan’s preference for building coal-fired generation capacity. Ultimately, it is up to the host country to decide the composition of its electricity mix. The Chinese government has a long-standing reluctance to interfere in decisions of this type. Moreover, China regards some of the CPEC coal power plants as environmentally friendly because they use relatively modern technologies and are expected to emit fewer greenhouse gas emissions than the fuel oil plants Pakistan is replacing. Third, there is a risk that the CPEC power projects will add to Pakistan’s sovereign debt burden, but multiple factors indicate that any increase in sovereign debt from these projects is unlikely to be the result of a deliberate strategy on the part of China. Although the debt financing arrangements for CPEC power sector projects primarily involve loans from Chinese banks to project companies wholly or partly owned by Chinese firms, these projects may increase Pakistan’s debt because of sovereign guarantees issued by Islamabad to support CPEC power projects and the liquidity crisis in Pakistan’s power sector known as circular debt. That said, several aspects of the China-Pakistan relationship and the large stake that China’s government and companies have in the success of CPEC indicate that Chinese interests are better served by sustainable CPEC projects than unsustainable ones.

7. Low-Carbon Heat Solutions for Heavy Industry: Sources, Options, and Costs Today

Author:
Julio Friedman

Institution:
Center on Global Energy Policy
Abstract:
Recent studies indicate there is an urgent need to dramatically reduce the greenhouse gas emissions from heavy industrial applications (including cement, steel, petrochemicals, glass and ceramics, and refining). Heavy industry produces roughly 22 percent of global CO₂ emissions. Of these, roughly 40 percent (about 10 percent of total emissions) is the direct consequence of combustion to produce high-quality heat, almost entirely from the combustion of fossil fuels. This is chiefly because these fuels are relatively cheap, are widely available in large volumes, and produce high-temperature heat in great amounts. Many industrial processes require very large amounts of thermal energy at very high temperatures (more than 300°C and often more than 800°C). For example, conventional steel blast furnaces operate at about 1,100°C, and conventional cement kilns operate at about 1,400°C. In addition, many commercial industrial facilities require continuous operation or operation on demand. The nature of industrial markets creates challenges to the decarbonization of industrial heat. In some cases (e.g., steel, petrochemicals), global commodity markets govern product trade and price. Individual national action on the decarbonization of heavy industry can lead to trade disadvantage, which can be made acute for foundational domestic industries (in some cases, with national security implications). This can also lead to offshoring of production and assets, leading to carbon “leakage” as well as local job and revenue loss (with political consequences). In many cases, lack of options could lead to dramatic price increases for essential products (e.g., cement for concrete, an essential building material). Risk of carbon leakage, price escalation, and trade complexity limits the range of policy applications available to address this decarbonization need. To explore the topic of industrial heat decarbonization, the authors undertook an initial review of all options to supply high temperature, high flux, and high volume heat for a subset of major industrial applications: cement manufacturing, primary iron and steel production, methanol and ammonia synthesis, and glassmaking. From the initial comprehensive set of potential heat supply options, the authors selected a subset of high relevance and common consideration: Biomass and biofuel combustion Hydrogen combustion (including hydrogen produced from natural gas with 89 percent carbon capture (blue hydrogen) and hydrogen produced from electrolysis of water using renewable power (green hydrogen) Electrical heating (including electrical resistance heating and radiative heating (e.g., microwaves) Nuclear heat production (including conventional and advanced systems) The application of post-combustion carbon capture, use, and storage (CCUS) to industrial heat supply and to the entire facility, as a basis for comparison The authors focus on substitutions and retrofits to existing facilities and on four primary concerns: cost, availability, viability of retrofit/substitution, and life-cycle footprint. In short, the paper finds: All approaches have substantial limitations or challenges to commercial deployment. Some processes (e.g., steelmaking) will likely have difficulty accepting options for substitution. All options would substantially increase the production cost and wholesale price of industrial products. For many options (e.g., biomass or electrification), the life-cycle carbon footprint or efficiency of heat deposition are highly uncertain and cannot be resolved simply. This complicates crafting sound policy and assessing technical options and viability. Most substitute supply options for low-carbon heat appear more technically challenging and expensive than retrofits for CCUS. Even given the uncertainties around costs and documented complexities in applying CO₂ capture to industrial systems, it may prove simpler and cheaper to capture and store CO₂. CCUS would have the added benefit of capturing emissions from by-product industrial chemistry, which can represent 20–50 percent of facility emissions and would not be captured through heat substitution alone. Critically, CCUS is actionable today, providing additional GHG mitigation to industrial heat and process emissions as other options mature and become economically viable. Hydrogen combustion provided the readiest source of heat of all the options assessed, was the simplest to apply (including retrofit), and was the most tractable life-cycle basis. Today, hydrogen produced from reforming natural gas and decarbonized with CCUS (blue hydrogen) has the best cost profile for most applications and the most mature supply chain, and it would commonly add 10–50 percent to wholesale production costs. It also could provide a pathway to increase substitution with hydrogen produced by electrolysis of water from carbon-free electricity (green hydrogen), which today would increase costs 200–800 percent but would drop as low-carbon power supplies grow and electrolyzer costs drop. Hydrogen-based industrial heat provides an actionable pathway to start industrial decarbonization at once, particularly in the petrochemical, refining, and glass sectors, while over time reducing cost and contribution of fossil sources. However, substitution of hydrogen will prove more difficult or infeasible for steel and cement, which might require more comprehensive redesign and investment. Most of the other options appear to add substantially to final production costs—commonly twice that of blue hydrogen substitution or CCUS—and are more difficult to implement. However, all options show the potential for substantial cost reductions. An innovation agenda remains a central important undertaking and likely would yield near-term benefits in cost reduction, ease of implementation, and a lower life-cycle carbon footprint. Prior lack of focus on industrial heat supplies as a topic leave open many possibilities for improvement, and dedicated research, development, and demonstration (RD&D) programs could make substantial near-term progress. To avoid commercial and technical failure, government innovation programs should work closely with industry leaders at all levels of investigation. New policies specific to heavy industry heat and decarbonization are required to stimulate market adoption. Policies must address concerns about leakage and global commodity trade effects as well as the environmental consequences. These policies could include sets of incentives (e.g., government procurement mandates, tax credits, feed-in tariffs) large enough to overcome the trade and cost concerns. Alternatively, policies like border adjustment tariffs would help protect against leakage or trade impacts. Because all options suffer from multiple challenges or deficiencies, innovation policy (including programs that both create additional options and improve existing options) is essential to deliver rapid progress in industrial heat decarbonization and requires new programs and funding. As a complement to innovation policy and governance, more work is needed to gather and share fundamental technical and economic data around industrial heat sources, efficiency, use, and footprint.

8. An Assessment of the Energy Innovation and Carbon Dividend Act

Abstract:
Growing public concern about the social, economic, and environmental impacts of climate change, along with pressure for lawmakers to introduce policy proposals that reduce emissions, have brought carbon taxes to the center of policy discussions on Capitol Hill. Thus far in 2019, seven different carbon tax legislative proposals have been introduced in Congress. The proposal with the most cosponsors, totaling 64 Democrats and 1 Republican as of the end of September 2019, is the Energy Innovation and Carbon Dividend Act (EICDA), introduced in February 2019 by lead sponsor Ted Deutch (D-FL). This study assesses the potential impacts of EICDA on the US energy system, environment, and economy. EICDA establishes a fee on each ton of greenhouse gas (GHG) emissions. It covers over 80 percent of gross national emissions. The fee starts at $15 per metric ton and increases by $10 or $15 each year, depending on future emissions levels. Revenue raised by the carbon fee is used for “carbon dividends,” a rebate to every eligible US citizen or lawful resident. The bill also includes measures to protect US competitiveness and to reduce the risk that companies will relocate their operations to a different country with laxer climate laws. Through the carbon fee and additional regulations if necessary, EICDA targets 90 percent emissions reductions by 2050 compared to 2016 levels. This study is part of a joint effort by Columbia University’s Center on Global Energy Policy (CGEP) and Rhodium Group to help policymakers, journalists, and other stakeholders understand the important decisions associated with the design of carbon tax policies and the implications of these decisions. This analysis uses a version of the National Energy Modeling System maintained by the Rhodium Group (RHG-NEMS) to quantify the energy and environmental implications of EICDA, focusing on outcomes through 2030. Supplemental analyses provide insights on how EICDA would affect households, the economy, and government budgets. The following are key results: GHG emissions decline substantially. Compared to 2005 levels, implementing EICDA as a stand-alone policy leads to economy-wide net GHG emissions reductions of 32–33 percent by 2025 and 36–38 percent by 2030. These emissions reductions exceed the targets in the EICDA proposal through 2030 and exceed the US commitments to the Paris Agreement over this period. Most of the near-term emission reductions occur in the power sector, where emissions fall 82–84 percent by 2030. Air pollution also declines. EICDA reduces local air pollution from power plants. Sulfur dioxide (SO2) and mercury emissions from the power sector decline by more than 95 percent and emissions of oxides of nitrogen (NOx) decline by about 75 percent by 2030 relative to a current policy scenario. Electricity generation shifts to cleaner sources. The price on carbon causes the US economy to shift from carbon-intensive energy sources to low- and zero-carbon energy sources. Coal is nearly eliminated from the power sector by 2030, with solar, wind, nuclear, and natural gas with carbon capture and storage all providing significantly larger generation shares compared to a current policy scenario. Energy prices rise but do not skyrocket. The price on carbon causes energy prices to increase for all carbon-emitting fuels, which leads to significantly higher overall energy expenditures, though within the range of recent historical variation. Taking two prominent examples, results show EICDA causing national average gasoline prices to increase by about 12 cents per gallon in 2020 and 90 cents per gallon in 2030 and causing national average electricity prices to increase by about 1 and 3 cents per kilowatt hour in 2020 and 2030, respectively. EICDA causes per capita energy expenditures to increase by $200-$210 in 2020 and $1,160-$1,170 in 2030 compared to a current policy scenario. In all years, annual per capita energy expenditures remain below the recent historical peak during the commodities crisis in 2008. The carbon dividend cushions energy price impacts. EICDA generates substantial revenue that is distributed in the form of equal dividend payments. EICDA generates $72–$75 billion in carbon tax revenues in 2020 and $403–$422 billion in 2030. This translates into an annual dividend for eligible adults of $250-$260 in 2020 and $1,410-$1,470 in 2030, with half those amounts also paid to eligible children. On average, the carbon dividend payments are comparable to the changes in energy expenditures caused by EICDA. Because higher-income households purchase far more carbon-intensive goods and services, distributing dividends equally implies that average low- and middle-income households receive more in dividends than they pay in increased economy-wide prices for goods and services resulting from the carbon tax. Net government revenue declines slightly, at least initially. Carbon tax-and-dividend policies are often described as “revenue neutral,” but the impacts of EICDA on government revenue are uncertain and likely negative in the near term. We estimate that the net government revenues under EICDA decline by roughly 10 percent of the annual carbon tax revenue in the early years of the policy. This estimate considers government revenue gains from taxing emissions and dividends, dividend payouts, and government revenue losses from reduced income and payroll taxes from those who pay the carbon tax. However, the proposal will also affect government revenue in other ways that are beyond the scope of our analysis, so the overall impacts on net government revenue is uncertain.

Columbia University’s Center for Global Energy Policy is undertaking a multiyear study on the prospects for and timing of peak oil demand. An essential piece of the puzzle is understanding what happens to global oil demand in the passenger vehicle sector, since it is the sector with the largest oil demand use today. Policy makers in a growing number of countries are supporting passenger vehicle electrification or a phaseout of fossil fuel passenger vehicles to reduce greenhouse gas emissions and improve urban air quality. To understand the trajectory of oil demand in this sector, it is important to comprehend the magnitude and timing of electric vehicle (EV) penetration. The pace of demand growth matters. If the world doesn’t move off oil at a rapid rate, it is important that policy makers recognize the need for investment in new oil supplies to prevent supply shortages and accompanying oil price spikes. Numerous studies analyzing the impact of EVs on oil demand have been published. It is difficult to compare these studies because they do not define the passenger vehicle sector the same way or provide underlying assumptions on a comparable basis. Last year, the author conducted a survey of all available global electric passenger vehicle penetration forecasts to compare underlying assumptions and the impact on oil demand. The author conducted a similar survey in 2019 to understand how views on EV penetration are changing. This report describes the results from the 2019 survey and indicates how views have changed since last year. Rationale for Studying the Passenger Vehicle Sector As shown in figure 1, the passenger vehicle sector is the largest sector of oil use, representing about one-quarter of the oil demand barrel. The passenger vehicle sector is a target for policy makers because full penetration of EVs could ultimately take nearly 25 million barrels per day of oil use out of the market. However, it is important to understand the other 75 percent of the oil demand barrel before assessing the prospects of peak oil demand. It should be noted that the passenger vehicle sector gets a disproportionate amount of attention from policy makers and the media because of the current focus on electrification and the greater ease of electrifying passenger cars versus other modes of transportation. For example, it is easier to electrify a passenger car than a heavy-duty truck, where the large and costly batteries required will reduce cargo carrying capacity due to weight limits on roads. It is also more challenging to electrify airplanes than passenger cars.

Abstract:
In the United States, commercial and residential buildings produce roughly 12 percent of greenhouse gas emissions. Most of these emissions come from burning fossil fuels for space heating. These emissions must be significantly reduced or eliminated for the US to achieve deep decarbonization goals, including net zero emissions by midcentury. Air source heat pumps (ASHPs) are powered by electricity, using well-established technology to move heat from outdoor air to indoor air. When powered by zero-carbon electricity, ASHPs provide space heating with almost no greenhouse gas emissions. ASHPs are especially effective for space heating in mild climates. In 2015, roughly 10 percent of US households (mostly in the Southeast) used air source heat pumps as their primary heating source.[1] ASHPs account for roughly one-third of residential space heating in Japan. The world’s largest ASHP market is in China, where sales are growing rapidly. Prominent studies on decarbonization of the US energy system focus on deployment of air source heat pumps as the primary strategy for reducing emissions from space heating. Some studies show near-universal electrification of space heating, suggesting that ASHPs (with some backup from electric resistance heaters) can be almost a silver bullet solution for decarbonizing space heating. These studies start with the assumption that fossil fuel furnaces and boilers will be gradually phased out. Other studies assume that electric heating technologies such as ASHPs will continue to compete against fossil fuel burning furnaces and boilers in the decades ahead. These studies conclude that furnaces and boilers will retain a significant share in space heating markets, even with technological progress and strong policy support for ASHPs, but often fail to explain why. Do high costs or inferior performance limit market penetration in these studies? Or do other barriers limit ASHP deployment? The answer has important implications for policy makers shaping decarbonization strategies. To help answer these questions, we built a simple model of ASHP adoption that estimates the lifetime costs of space heating and cooling configurations in three US cities with markedly different climates and energy costs: Atlanta, Georgia; San Diego, California; and Fargo, North Dakota. The model analyzes the choices facing hypothetical consumers installing new heating and cooling equipment in residential buildings. The consumers have the option to purchase an ASHP for heating and cooling (with backup if needed) or a natural gas furnace and air conditioner. Based on the model results and related research, we conclude: Air source heat pumps are cost competitive today in places where electricity is cheap and the climate is mild. With climate policies consistent with rapid decarbonization and reasonably foreseeable technological progress, air source heat pumps are the low-cost option for typical residential buildings across much of the US by the mid-2030s. Even in the very cold climate of Fargo, North Dakota, the combination of a price on carbon emissions and steady innovation in ASHPs causes ASHPs (with an electric resistance heater as a backup) to be cost competitive with new natural gas furnaces and air conditioners by the 2030s. If the United States commits to the rapid decarbonization of space heating by midcentury, the costs and performance of ASHPs are unlikely to be major barriers to deployment. However, other important barriers may persist, including contractors’ and homeowners’ greater familiarity with incumbent fossil fuel technologies and the slow turnover of the building stock. As a result of these additional barriers, emissions pricing and technological progress alone may not lead to deployment of air source heat pumps in the United States sufficient to achieve deep decarbonization by midcentury. That would likely require additional policy instruments such as technology standards, emissions caps, or mandates. Other technologies can also contribute to decarbonizing space heating, including renewable natural gas, hydrogen produced with carbon capture and storage (CCS) or electrolysis, and centralized or district heating. Each of these options comes with challenges that will require policy support to overcome. This study does not point to a proper balance between ASHPs and other space heating decarbonization technologies. More research is needed to compare different approaches and strategies. In the meantime, our analysis suggests little if any downside to pursuing ambitious policies to promote deployment of ASHPs, prioritizing regions where heat pumps are currently most cost effective. A large-scale increase in ASHP deployments is likely to be an important part of any space heating decarbonization scenario.
