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.

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.

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.
