In last year's Copenhagen Climate Change Conference, China announced its carbon emission targets and a series plans to achiev e the goal. This paper investigates the potential impacts on China's current fast economic growth and the feasibility of the country to realise the country' s promise. The emission-economic relationship is confirmed after reviewing theoretical frameworks including both to p-d own and bottom-up approach es. Carbon emissions will in crease if a country's output l ev el grows, unless the economy reaches a structural change. On the other side, economic growth will be affected by a restrictive emissions control policy. W ith such an impact, the feasibility of China's emissions target is necessary to be examined. By exploring China's existing and po tential technology and policy to ols, which focus on energy development and conserv atio n, China's effo rts suggest a h igh possibility to realize its promise with minor damages on the economic develo pment. Statistical projections on China's future emissions are integrated to provide an estimate about the po ssibility of achieving the target Though C hina's implemented technology and policy to ols are not as so phisti cated as d eveloped countri e s, fo recasts have shown that China is able to achiev e its emissions target by 2020, w ith continues growth in both economic and emission levels.
