In recent years, our clean coal technology made some breakthrough by means of introduction, digestion, and innovation. But compared with the developed countries, the use of clean coal technology in our country is not common for the unsound policies and standards, the lack of market mechanism, insufficient capital investment, decentralize of trade management and so on. We can effectively promote the development of clean coal technology, promote our country's energy consumption to transform extensive to intensive consumption and gradually realize a coordinated development between the energy, economy and environment by completing the relevant policies, laws and regulations of technology, finance, taxation, environmental protection, perfecting the independent innovations and technology admittance mechanism, increasing financial investment, encouraging private investment and setting up specialized standard managing and setting body of clean coal technology.
