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.

During a candid conversation at the Harvard Kennedy School, prominent women leaders in the science and media industries recently talked about their efforts to remedy this. They ignited a fervent discussion and identified achievable goals that both professional women and their male and female bosses can work toward. The event, “Sexism, Science, and Science Writing: Promoting Women Leaders in the Lab and the Newsroom,” drew a standing-room-only crowd of more than 100 women and men of all ages—from a female high school student to senior astrophysicists and science writers.

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.
