Scientists from three universities demonstrate that buying a product made in China causes significantly higher carbon dioxide emissions than purchasing the same product made elsewhere.

International trade has become the fastest growing driver of global carbon emissions, with large quantities of emissions embodied in exports from emerging economies. International trade with emerging economies poses a dilemma for climate and trade policy: to the extent emerging markets have comparative advantages in manufacturing, such trade is economically efficient and desirable. However, if carbon-intensive manufacturing in emerging countries such as China entails drastically more CO2 emissions than making the same product elsewhere, then trade increases global CO2 emissions.

China is the world's largest emitter of carbon dioxide, accounting for one-quarter of the global total in 2013. Although the country has successfully lowered the rate of emissions from industry in some cities through improved technology and energy-efficiency measures, rapid economic growth means that more emissions are being added than removed. Without mitigation, China's CO2 emissions will rise by more than 50% in the next 15 years.

The magnitude and growing annual rate of growth of China's carbon emissions make this country the major driver of global carbon emissions and thus a key focus for efforts in emissions mitigations. This report presents independent data on China's carbon emissions from 1950–2012, and provides a basis to support mitigation efforts and China's low-carbon development plan.

Each year, the Science, Technology, and Public Policy (STPP) Program at the Belfer Center for Science and International Affairs at the Harvard Kennedy School welcomes new pre- and post-doctoral fellows and visiting researchers to a select team of scholars exploring the critical role that science and technology play in everyday life.

This discussion paper examines the development of water markets as a solution to water scarcity in China, with particular focus on Water Rights Trading (WRT). Water scarcity is an issue of growing concern for China, particularly in the north, where a combination of limited water supplies, economic growth, and population increases are increasingly straining water resources. The Chinese government has moved enthusiastically toward an embrace of market mechanisms to address water scarcity, with WRT being the preferred policy instrument in the agricultural sector, which accounts for the majority of water use in China. This discussion paper proposes several policy recommendations to improve the development of water markets in China, in particular by lowering the transaction costs to establishing markets and improving policy coordination.

China committed itself to reduce the carbon intensity of its economy (the amount of CO2 emitted per unit of GDP) by 40–45% during 2005–2020. Yet, between 2002 and 2009, China experienced a 3% increase in carbon intensity, though trends differed greatly among its 30 provinces. Decomposition analysis shows that sectoral efficiency gains in nearly all provinces were offset by movement towards a more carbon-intensive economic structure.

"An ambitious deal might also stimulate more demand for innovations in clean technologies, in which China is emerging as a global leader. But because of the UN's decision-making process, in which all its members have to agree on a new deal, Xi Jinping is in the powerful position of being able to commit to only as much emission reductions as fit his domestic policy agenda."

China has ambitious goals for developing and deploying electric vehicles (EV). The stated intention is to “leapfrog” the auto industries of other countries and seize the emerging EV market. Since 2009, policies have included generous subsidies for consumers in certain locations, as well as strong pressure on local governments to purchase EVs. Yet four years into the program, progress has fallen far short of the intended targets. China has only about 40,000 EVs on the road, of which roughly 80% are public fleet vehicles such as buses and sanitation vehicles.

"...[U]ntil now, Beijing's response to unmet energy demand has focused primarily on securing resources overseas, and building infrastructure for imports. China now generates more electricity from imported coal than from nuclear, wind and solar combined. Without a strong, coordinated policy shift, the country will depend on fuel imports for most of its energy consumption by the time it becomes a developed country."
