As of 2011, buildings accounted for 28% of China’s energy consumption. Upward pressures on building energy use include population and economic growth, urbanization, and rising living standards.
China has adopted a series of domestic policies, including building energy codes, policies and incentives based on green building ratings, and building retrofit programs, to increase the energy efficiency of buildings.
China’s building codes could reduce building energy use by 13-22% and CO2 emissions by 14-20% from business-as-usual by the end of this century, depending on their stringency and coverage.
China’s nationally determined contribution for the Paris Agreement and 13th Five Year Plan indicate stronger action on building energy efficiency.
Building efficiency policies have created a market in China for energy-efficient materials and products, which U.S. companies are poised to help supply.
Q: How have the joint U.S.-China announcements helped create momentum for global climate action?
Q: What steps is China taking toward its goals? A: China has been taking action to strengthen all the building blocks of its low-carbon strategy, and continues to do so.
Q: Do we have reason to believe that China will follow through on its commitments? A: Yes. China has already made progress on its energy and emissions targets and has strong reasons of national interest to build on its current efforts.
Q: What is the benefit of the U.S. and China, and many other countries, taking action together?
Q: With countries acting together, each can have confidence its actions are part of a global effort to address climate change. Moving forward together yields increasing opportunities for all.
As of 2015, China got 12% of its total primary energy from non-fossil sources. China’s 13th Five Year Plan aims to increase the share of primary energy from non-fossil sources to 15% in 2020. As part of its nationally determined contribution (NDC) to the Paris Agreement, China committed to increase the non-fossil share to around 20% by 2030.
Wind Power: China ranks first in the world in installed wind power capacity, with 139 GW by the end of 2015.
Solar Power: China has surpassed Germany to become the world leader in installed solar power, with 50 GW of solar capacity installed by the end of 2015.
China is the world’s leading installer of solar and wind power, with world records for capacity installation in 2015 and targets for 100 GW of solar and 200 GW of wind installed by 2020.
Investment: For the fourth straight year, China was the number one investor in renewable energy in 2015 with $102.9 billion, accounting for over a third of global investment.
As of 2014, China got 11.2% of its total primary energy from non-fossil sources. Official targets aim to increase the share of primary energy from non-fossil sources to at least 11.4% by the end of 2015 and 15% in 2020. China’s contribution to the anticipated international climate agreement includes a target to increase the non-fossil share to around 20% by 2030.
Wind Power: China ranks first in the world in installed wind power capacity, with about 110 GW by the end of 2014. China is also the world’s fastest growing installer of wind power, and it aims to have 200 GW installed by 2020.
Solar Power: China had nearly 33 GW of solar power capacity installed by the end of 2014, and is attempting to dramatically scale up, planning to install an additional 17.8 GW of solar projects in 2015 and a total of 100 GW by 2020.
Investment: China was the number one investor in renewable energy in 2014, accounting for nearly a third of global investment.
The U.S.-China Renewable Energy Partnership (USCREP) aims to advance the viability of renewable energy by addressing barriers to deployment and grid integration.
The USCREP promotes policy, planning, and coordination for renewable energy; supports efficient grid integration for renewable generation; participates in efforts to develop international standards for the quality of wind and solar technology; and promotes the deployment of distributed solar generation and concentrated solar power.
Opportunities for U.S. clean technologies through USCREP-fostered cooperation lead to potential job creation and expanding exports.
China has been experimenting with many different policies to control carbon and energy intensity
By updating building codes to international best practices, China could save in 20 years an equivalent of the amount of CO2 that would be emitted by 15 large coal fired power plants over 20 years.
If China continues to improve fuel efficiency standards at its current rate, it will save the equivalent of the amount of CO2 that would be emitted by 10 large coal fired power plants over 20 years.
By expanding from pilots to a national level policy, the use of environmental priorities in selecting what electricity sources to use to respond to increased demand could significantly reduce coal use in the power sector.

A U.S.-Chinese team led by the Harvard China Project has developed a comprehensive framework for evaluating the economic and environmental costs and benefits of national policies to control air pollution and CO2 emissions in China.
Contrary to some perceptions of Chinese inaction on air pollution, China’s SO2 control policy of 2006-2010 may have been one of the most swiftly successful air pollution policies on record judged by key criteria: sulfur emissions fell sharply and prevented as many as 74,000 premature deaths from fine particle (PM2.5) air pollution in 2010 alone, all at little economic cost.
Looking to the future, a modest tax on carbon dioxide, starting small and rising to about $6.50 per ton in 2020 (in 2007 dollars), could lead to a 19% reduction in China’s CO2 emissions in 2020 compared to a scenario with no tax, with little effect on GDP growth and consumption over the long run.
Such a carbon tax would also deliver powerful ancillary benefits: reduced concentrations of an array of domestic air pollutants and prevention of as many as 89,000 premature deaths a year by 2020.
