Environment & Climate Change

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.

Cambridge, MA – The Belfer Center for Science and International Affairs has named Daniel Schrag, Sturgis Hooper Professor of Geology and Director of the Center for the Environment at Harvard University, to lead its Science, Technology, and Public Policy program. STPP, one of Harvard's most collaborative and cross-disciplinary programs, is renowned world-wide for its cutting-edge research on technology innovation, nuclear non-proliferation and safety, climate science and policy, cybersecurity, and globalization and development.

The New Harvest argues that Africa can feed itself in a generation and help contribute to global food security despite its history of persistent food shortages and the rising threat of climate change. This new edition provides ideas on how to place agriculture at the center of the continent's long-term economic transformation. It demonstrates how policy coordination can help realize agriculture's full potential as a motherboard for other economic activities.

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.
