As the effects of climate change become more widespread and alarming, U.N. Secretary-General António Guterres has called on nations to step up their plans for cutting greenhouse gas emissions. Every country has a part to play, but if the world’s largest emitters fail to meet their commitments, the goal of holding global warming to a manageable level will remain out of reach.
U.S. carbon dioxide emissions are on the rise after several years of decline, due in part to the Trump administration’s repeal or delay of Obama administration policies. In contrast, China – the world largest emitter – appears to be honoring its climate targets under the 2015 Paris Agreement, as we documented in a recent article with colleagues.
We study many aspects of China’s energy and climate policy, including industrial energy efficiency and reforestration. Our analysis indicates that if China fully executes existing policies and finishes reforming its electric power sector into a market-based system, its carbon dioxide emissions are likely to peak well before its 2030 target.

China’s climate portfolio
Over the last decade China has positioned itself as a global leader on climate action through aggressive investments and a bold mix of climate, renewable energy, energy efficiency and economic policies. As one of us (Kelly Sims Gallagher) documents in the recent book “Titans of the Climate,” China has implemented more than 100 policies related to lowering its energy use and greenhouse gas emissions.
Notable examples include a feed-in-tariff policy for renewable energy generators, which offers them a guaranteed price for their power; energy efficiency standards for power plants, motor vehicles, buildings and equipment; targets for energy production from non-fossil sources; and mandated caps on coal consumption.
China has added vast wind and solar installations to its grid and developed large domestic industries to manufacture solar panels, batteries and electric vehicles. In late 2017 it launched a national emissions trading system, which creates a market for buying and selling carbon dioxide emissions allowances. This was a profoundly symbolic step, given that the United States still has not adopted a national market-based climate policy.

Most of these policies will produce additional benefits, such as improving China’s energy security, promoting economic reform and reducing ground-level air pollution. The only major program explicitly aimed at reducing carbon dioxide is the emissions trading system.
Major challenges and policy gaps
Under the Paris Agreement, China committed to start reducing its carbon dioxide emissions and derive 20% of its energy from non-fossil fuels by around 2030. But when Chinese emissions rose in 2018, international observers feared that Beijing might fail to meet its targets. We analyzed China’s actions to assess that risk.
In our review, we found that the policies with the greatest influence over China’s projected emissions in 2030 were power sector reform, industrial transformation, industrial efficiency, emissions trading and light-duty vehicle efficiency.
Reforming the electric power sector is an essential step. Traditionally, electricity pricing schemes in China were determined by the National Development and Reform Commission, which leads the country’s macroeconomic planning. They favored existing power producers, particularly coal plants, not the cleanest or most efficient sources.
China committed to electric power reform, including emission reductions and greater use of renewables, in 2015. Converting to a process under which grid managers buy electricity from generators starting with the lowest-cost sources should facilitate installation and use of renewables, since renewable electricity has almost zero marginal costs. Meanwhile, renewable energy projects across China, especially solar, have become cheaper than grid electricity.
Even as China made big investments in wind and solar power in recent years, it also kept building coal plants. Power sector reform will help reduce the resulting overcapacity by stopping planned additions and encouraging market competition.
But success is not guaranteed. The affected companies are giant state-owned enterprises. There is political resistance from owners of existing coal-fired power plants and from provinces that produce and use a lot of coal. The current U.S.-China trade war is slowing China’s economic growth and spurring rising concerns about employment, which could further complicate the reform process.
China’s emissions trading system has had a very modest impact so far because it set a low initial price on carbon dioxide emissions: US$7 per ton, increasing by 3% annually through 2030. But our analysis found that emissions trading, which allows low-carbon generators to make money by selling emissions allowances that they don’t need, could become influential over the longer term if it can sustain a much higher price. If China reduces its cap on total carbon dioxide emissions after 2025, which will increase the price of emissions allowances, this policy could become a major driver for emission reductions in the power sector.
Energy efficiency standards, particularly for coal-fired power plants, factories and motor vehicles, will also be very important over the coming decade. To continue driving progress, China will need to update these standards continuously.
Finally, there are some important gaps in China’s climate policies. Currently they only target carbon dioxide emissions, although China also generates significant quantities of other greenhouse gases, including methane and black carbon.
And China is contributing to emissions outside of its borders by exporting coal equipment and directly financing overseas coal plants through its Belt and Road Initiative. No nation, including China, currently reports emissions generated abroad in its national emissions inventory.
The biggest challenge China faces in achieving its Paris targets is making sure that business and local governments comply with policies and regulations that the government has already put in place. In the past, China has sometimes struggled with environmental enforcement at the local level when provincial and city governments prioritized economic development over the environment.
Assuming that China does carry out its existing and announced climate and energy policies, we think its carbon dioxide emissions could likely peak well before 2030. In our view, Chinese leaders should focus on completing power sector reform as soon as possible, implementing and strengthening emissions trading, making energy efficiency standards more stringent in the future and developing new carbon pricing policies for sectors such as iron, steel and transportation.
If they succeed, U.S. politicians will no longer have “But what about China?” as an excuse for opposing climate policies at home.

Climate Leviathan: A Political Theory of Our Planetary Future
by Joel Wainwright and Geoff Mann
How climate change will affect our political theory—for better and worse. Despite the science and the summits, leading capitalist states have not achieved anything close to an adequate level of carbon mitigation. There is now simply no way to prevent the planet breaching the threshold of two degrees Celsius set by the Intergovernmental Panel on Climate Change. What are the likely political and economic outcomes of this? Where is the overheating world heading? Available On Amazon
Upheaval: Turning Points for Nations in Crisis
by Jared Diamond
Adding a psychological dimension to the in-depth history, geography, biology, and anthropology that mark all of Diamond's books, Upheaval reveals factors influencing how both whole nations and individual people can respond to big challenges. The result is a book epic in scope, but also his most personal book yet. Available On Amazon
Global Commons, Domestic Decisions: The Comparative Politics of Climate Change
by Kathryn Harrison et al
Comparative case studies and analyses of the influence of domestic politics on countries' climate change policies and Kyoto ratification decisions. Climate change represents a “tragedy of the commons” on a global scale, requiring the cooperation of nations that do not necessarily put the Earth's well-being above their own national interests. And yet international efforts to address global warming have met with some success; the Kyoto Protocol, in which industrialized countries committed to reducing their collective emissions, took effect in 2005 (although without the participation of the United States).
