Abstract: The opportunities about speeding up natural gas utilization and business development were analyzed from three aspects：economic and environmental factors of natural gas utilization，shale gas development，and technology progress when China is entering low carbon era. The opportunities of speeding up natural gas business development would have matured. The importance of natural gas utilization for optimization of transportation fuel structure and improvement of environmental quality was discussed from energy consumption and environmental protection，and the natural gas business development status of PetroChina was introduced. In order to promote China’s natural gas industry quality and benefits，relevant suggestions on natural gas utilization were put forward，China should make great efforts to cultivate LNG downstream market with scale economy，speed up layout and construction of LNG liquefaction plant and filling stations，improve natural gas downstream industry chain，accelerate comprehensive utilization of coastal LNG，develop distributed energy of natural gas，and at the same time，lay emphasis on shale gas exploration and mining technology development.
