Fossil energy is the prime culprit for huge GHGs emission, covering almost 90 percent of the total amount. There has been a great deal of discussion about reducing GHGs in China, however, the biomass energy which is of carbon zero-emission characteristic has not been paid much attention. Furthermore, biomass's unique function of carbon negative emission is far from being recognized. This paper describes the mechanism of biomass's carbon negative emission and its theoretical potentials to China and the world. Several real practical and feasible ways, particularly the way of reducing biomass-derived methane, for carbon negative emission are probed. It is discovered that biomass-derived carbon sequestration is far superior to geological CO₂ storage, and highly feasible as well. The world climate change circle pays much attention to the biomass's function of GHGs emission and to the effects of its unique carbon negative emission in particular. Someone even calls it the last prospect for realizing the global 1.5℃ scenario. The situation of severely ignoring biomass's great effects on GHGs reduction should be shifted as soon as possible.
