British coal reduction and clean use of the characteristics of the climate change bill + carbon budget, taxes on climate change, emissions trading system in Germany and clean utilization of coal quantity-reducing characteristics, eliminate backward production capacity, the upgrading of energy efficiency, energy transformation and clean utilization of coal quantity-reducing characteristics of the United States Clean Air Act (regulation) to convert carbon dioxide into the pollutants, shale gas cleaning, power planThe experience of the four countries is compared with that of Britain and Germany, whose coal reduction measures are strengthened to make them able to cope with climate change;The United States pays more attention to clean use of coal through market means, and strict air quality standards restrain the growth of coal.Japan is still relying on coal to support its economy in the short term because of energy security concerns, delaying coal reductionTotal amount control model for China's coal consumption, to establish and enforce its strict air quality standard -- removing coal subsidies, competitive - the use of the international energy market, improve the energy change of the domestic energy structure, technology progress, improve the efficiency of energy utilization and realize clean use of coal consumption to power generation and metallurgical industry concentration, more efficient use of coal, energy supply security concerns, on the premise of meet the safety standards and environmental assessment exploitation of coal, on the premise of meet the emission standard clean use of coal
