摘要

In response to severe haze pollution,the Chinese government has announced a series of policies focusing on controlling emissions from coal consumption."Ultra-low emission"(ULE)technologies have the potential to dramatically reduce emissions from coal-fired power plants,and have been deployed at some facilities in recent years.This paper estimated the potential environmental benefits of the widespread adoption of ULE in the Jing-Jin-Ji Region.Atmospheric modeling scenarios were analyzed for three cases:a"standard"scenario assuming no ULE deployment,a"best case"scenario assuming complete adoption of ULE across all power plants in the region,and a"natural gas"scenario,assuming emissions factors consistent with natural gas-fired power generation.The simulations show that the widespread adoption of ULE technologies can be an effective and economically competitive option for reducing the impacts of coal-fired power generation on air quality.
