压减燃煤：电厂减煤优先还是民用散煤淘汰优先？--以北京市为例的费用效益分析

o cope with the serious air pollution, in particular the widely concerned haze problem, the Chinese State Council issued the National Action Plan on Air Pollution Prevention and Control which requires that Beijing- Tianjin-Hebei region should achieve a negative growth of total coal consumption by 2017. Coal reduction and substitution has been chosen as a key strategy to control air pollution and its ultimate goal should be to efficiently protect the public health. This study calculates the costs and benefits of coal reduction and substitution interventions for coal fired power plants and the residential coal consumption in Beijing with 2011 as the base year. The result of the social net benefits per ton of coal reduced suggests that the coal reduction in residential sector is more efficient than that in coal fired power plants. The net benefit/cost and benefit/cost ratios show a more significant superiority in residential sector. This analysis indicates that the current coal consumption reduction plan in Beijing with the priority in coal fired power plants higher than that in residential sector will realize limited environmental and health benefits, and may induce huge social cost in the long run. Reevaluate and adjustment of this policy is urgently needed
