Abstract: Global warming has been becoming a world wide issue in which anthropogenic emission of greenhouse gases (CO 2, CH 2, N 2O) plays a main role. According to the analysis of international study on it since 1990’s, this paper summarized the main contents and the methods of international research on the impacts of human activities on carbon emission. The main contents are: ① energy consumption and carbon emission, including the transform of the structure of energy consumption and the construction of low emission supply system (LESS) ; ② economic development and carbon emission, which focus on the relationship between the different economic development style and carbon emission, including economic development stage, economic structure, and economic development speed; ③ agriculture and carbon cycle, including the relationship between land use/land cover change and carbon cycle, impacts of management of agricultural land and restoration of degraded land on carbon cycle, and the influence of agricultural development level and structure’s change on carbon emission; ④ the economic cost of CO 2 emission limits and the strategies for optimal CO 2 emission abatement. Because carbon emission process caused by human activities is very complicated, more and more synthetical models, based on a vast amount of data, such as carbon emission/energy model, economic model of energy consumption and carbon emission limitation, DIAM model, etc., are used for analysis besides the traditional regression analysis and regional contrast analysis. Meanwhile, several issues on carbon cycle research that must be emphasized in China were analyzed.

Key words: Carbon emission, human activities, international latest development
