Environmental Effects and Its Assessment for Shale Gas Large-Scale Development of China

Shale gas is a new kind of unconventional gas and can be used with a environmental acceptable way with high energy efficiency. The large-scale development of shale gas in china will contribute to energy structure referring both in supply and demand as well as promoting the extent of carbon emission reduction. However, because of special technique used in the process of shale gas development, environmental concerns gain much attention. It reported that practice of shale gas development can partly do harm to local air (atmospheric environment), water body environment, geology and ecological environment. Therefore, there is absolute negative impact of shale gas development on the environmental quality. To this point, shale gas development in china is facing opportunity and challenge.
