Science, Technology, and Public Policy

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.

"To harness the globally available technologies, African leaders will need to take into account the multisectoral dimension of African agriculture and pay particular attention to the urgency of investing in rural infrastructure, higher agricultural training and creation of regional markets."

"The rising concern over global food price volatility has put agriculture at the center of international diplomacy. But unlike the 1950s when food aid became a major tool in international relations, modern interactions among states are being defined by trade and knowledge transfer. A new field — agricultural diplomacy (AgroDiplomacy) — is emerging as countries learn more about their shared ecological experiences and agricultural trade interests. The prospects for building such relations are evident in the rise in cooperation between Africa and Latin America."

China's dependency on coal fuels the country's phenomenal economic growth but at a major cost to the country's air and water quality, ultimately threatening human health and the country's continued economic growth. The Chinese government's efforts to put China onto a cleaner, low carbon development path have been substantial; however China's pollution and greenhouse gas emissions continue to grow. In an attempt to develop its own advanced coal generation technologies to improve the country's air quality and energy efficiency, the Chinese government is investing heavily in gasification and other technologies that can be employed in carbon capture and sequestration (CCS) applications. This investment has turned China into a global laboratory for CCS pilot projects, attracting foreign governments, multilateral institutions, nongovernmental organizations, and business partners.

Carbon Capture and Storage (CCS), as an option in the portfolio of mitigation actions to combat climate change, is expected to have far-reaching implications for China. This paper (1) explores the strategic significance of CCS for China by making an extreme scenario analysis of Chinese power sector in 2030; (2) provides an overview of the recent CCS activities in China; and (3) identifies the major challenges with respect to CCS development in China and put forwards immediate strategies.

China's climate change policy expresses both continuity and change over time. Continuity is observed in China's active involvement in policy formation, both domestically and internationally. Changes are reflected both in China's institutional arrangements on climate change mitigation and adaptation and increasing flexibility in international negotiations. Both continuity and change can be attributed to international and domestic factors. Among China's foreign policy objectives are enhancing its international image, international engagement, sovereignty concerns, and solidarity with developing countries. Domestic objectives include the need for continued economic development, increased attention to environmental protection, and social learning effects.

"...it is a mistake to see high prices as a proxy for actual hunger. Most of the world's hungry citizens do not get their food from the world market, and most who rely on the world market are not poor or vulnerable to hunger."

China's Ministry of Science and Technology launched the China-Africa Science and Technology Partnership on November 24, 2009.  The ministry announced that technological cooperation will be enhanced in areas such as water management and conservation, sanitation, crop breeding, health, and renewable energy. One hundred joint research partnerships will be created, and 100 African scientists at the postdoctoral level will have the opportunity to conduct research at China's technology parks, research institutes, and private enterprises. Chinese scientists and engineers will also travel to African countries to provide technical guidance, and in order to increase the research capacities of African countries, China will also donate laboratory equipment.

Science, Technology, and Globalization Project Director Calestous Juma shared his insights into the history and future of Sino-African relations in a February 2008 interview with that's China columnist Jing Zhang.
