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.

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.

Energy technology innovation is the key to driving the technological changes that are necessary to meet the challenge of mitigating energy-related greenhouse gas emissions to avoid 'dangerous climate change.' Success in innovation requires the enhancement of public investment in the innovation process, the creation of markets for low-carbon technologies through stronger climate policies, and a continued focus on energy access and equity.

Probabilistic estimates of the cost and performance of future nuclear energy systems under different scenarios of government research, development, and demonstration (RD&D) spending were obtained from 30 U.S. and 30 European nuclear technology experts. The majority expected that such RD&D would have only a modest effect on cost, but would improve performance in other areas, such as safety, waste management, and uranium resource utilization. The U.S. and E.U. experts were in relative agreement regarding how government RD&D funds should be allocated, placing particular focus on very high temperature reactors, sodium-cooled fast reactors, fuels and materials, and fuel cycle technologies.

By analyzing the institutions that have been created to stimulate energy technology innovation in the United States, the United Kingdom, and China—three countries with very different sizes, political systems and cultures, natural resources, and histories of involvement in the energy sector—this article highlights how variations in national objectives and industrial and political environments have translated into variations in policy.

The key findings derived from this study improve the understanding of the effects of China's domestic investment on its energy consumption expansion and reflect the fact that China's rapid urbanization and industrialization processes are among the main reasons for the large amount of energy consumption in China. The authors provide some quantitative information for further determining the energy-saving potentials of China's economy during these processes.

Using the bidding prices of participants in China's national wind project concession programs from 2003 to 2007, this paper built up a learning curve model to estimate the joint learning from learning-by-doing and learning-by-searching, with a novel knowledge stock metric based on technology adoption in China through both domestic technology development and international technology transfer. The paper describes, for the first time, the evolution of the price of wind power in China, and provides estimates of how technology adoption, experience building wind farm projects, wind turbine manufacturing localization, and wind farm economies of scale have influenced the price of wind power.

An integrated carbon dioxide (CO2) capture and storage (CCS) system requires safe and cost-efficient solutions for transportation of the CO2 from the capturing facility to the location of storage. While growing efforts in China are underway to understand CO2 capture and storage, comparatively less attention has been paid to CO2 transportation issues. Also, to the best of our knowledge, there are no publicly available China-specific cost models for CO2 pipeline transportation that have been published in peer-reviewed journals. This paper has been developed to determine a first-order estimate of China's cost of onshore CO2 pipeline transportation.

The authors of this article propose, summarize, and present strategic ideas as policy implications for China's decision-makers. In conclusion, they determine that China should enhance strategic planning and regulation from a life cycle viewpoint of the whole society, prioritize energy saving, continuously improve incumbent energy, and rationally develop alternative energy.
