Environment & Climate Change

By 2099 the nature of democratic politics could change in costly ways for politicians because of climate change, according to Nick Obradovich, research fellow with Harvard Kennedy School’s Science, Technology, and Public Policy program. Leveraging a century’s worth of political science research, he predicts in an article in Springer’s journal Climatic Change that voters’ disgruntlement about the societal effects of climatic extremes and weather-related disasters they experience will translate into more frequent turnover of political parties elected in and out of office, and will keep politicians of especially warmer, poorer countries more on their toes than is currently the case.

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.
