Global warming is a common problem of mankind. According to IPPC inference, in the period of 1850-1899 and the period of 2001-2005, global average temperature has increased by 0.67 degrees, which is likely(greater than 90% chance) caused by human activities, greenhouse gas emissions. If human beings still keepthe existing level of greenhouse gas emissions, the trend of future global warming will accelerate. To the endof this century the average global temperature will likely continue to rise by 1.8 degrees to 4 degrees. Inorder to reduce global warming, to achieve the sustainable development of human society to control humanactivities, greenhouse gas emissions is the general consensus of mankind.
