Abstract: Since the industrial revolution, the emission of greenhouse gases (GHGs) in energy field gradually becomes one of the major anthropogenic sources with the wide utilization of fossil fuel. The contradiction among energy, environment and the economic development also becomes the focus that the governments of all countries pay much more attention to in recent years. How to reduce the GHGs emission in energy field effectively has become the worldwide scientific problem in terms of environment, economy, politics, diplomacy and the like. In this paper, the situation of development and utilization of energy and the main sources of carbon dioxide, methane, nitrous oxide in energy field in China are reviewed and discussed. At last, some effective approaches with twin wins in greenhouse gases mitigation and sustainable exploitation and utilization of energy are proposed.Generally speaking, the way to mitigate the emissions of GHGs in energy field can be summarized as the following three kinds of measures. The first is the technology means, namely, quickening the exploitation of energy-saving technology, enhancing the utilization technology of renewable energy and clean energy, whatever, strengthening the cooperation with the developed countries in the field of the relative technology researches is also very important. The second means is the economical and financial means that refers to provide a series of the preferential policy including offer preferential tax revenue, public subsidy and low-interest loan and other preferences to the relevant enterprises. Thirdly, it is the administrative means, including strengthen and improve the macro-control mechanism and promote the construction of rules and laws on the exploitation and utilization of energy and environmental protection, establishing reasonable strategy of energy consumption and industrial development and increasing the fund input of science and technology in energy field and so on, at the same time, laying stress on the propaganda of energy-saving and environment protection is also very necessary.
