Science, Technology, and Public Policy

The Belfer Center began researching energy technology issues in the late 1990s. Its mission was “to determine and promote the adoption of effective strategies for developing and deploying cleaner and more efficient energy technologies that can reduce greenhouse gas emissions, reduce dependence on fossil fuels and stress on water resources, and improve economic development.”

In this issue, we look at the history and influence of the Center’s energy innovation efforts in the past two decades by focusing primarily on ETIP’s work in the U.S. and China.

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.

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."

"...[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."

"Although the country has successfully imported model environmental policies, it has yet to develop the complex institutional infrastructure needed to make them work, especially an independent judiciary, a capable bureaucracy, and effective co-operation between central and local governments."

"Biotechnology offers Africa a wider range of economic opportunities than the Green Revolution did. It is already being used to improve food production and establish or revive cotton production. Its economic impact is therefore likely to go well beyond the farm sector to include industrial development."
