Coal burning in Beijing attributes 22.4% of air pollution in Jing-Jin-Ji region, that in Tianjin attributes 27% and that in Shijiazhuang attributes 28.5%, according to source apportionment analysis for the area If coal burning pollution in rural areas during winter can be eliminated, PM2.5 concentration can be improved by 20% for Jing-Jin-Ji region, and 40% for Beijing alone, as estimated in a report published on Proceedings of the National Academy of Sciences of United States. As a matter of fact, coal burning contributes significantly to air pollution in Jing-Jin-Ji region and thus clean energy should be utilized widely as substitution of it, pushing relative policies to be designed and taken into effects.
For the sake of air quality improvement in Jing-Jin-Ji region，the Innovation Center for Clean-air Solutions (ICCS, Secretariat for Clean Air Alliance of China) and Beijing Municipal Research Institute of Environmental Protection are entrusted by Beijing Environmental Protection Bureau with the support of Energy Foundation to present policy recommendation about Transition to Clean Energy for Jing-Jin-Ji region on the basis of analyzing cost and emission reduction effects through typical cases. The preliminary plan has just been formed after heated-up discussion during Jing-Jin-Ji region clean-air transition seminar.
It is essential at first to investigate present policies, current energy use condition and the implementation of transition to clean energy, which includes total energy consumption, energy structure, coal consumption, energy use condition such as coal-fired boiler and household coal, range and progress of the transition, etc. Based on that, certain transition types should be selected for further case investigation. Finally, recommendation on policy making will be put forward with reference to experience of other regions in China and will be accomplished in June 2017. Two documents will be published, namely Typical Case Analysis and Policy Recommendation on Transition to Clean Energy for Jing-Jin-Ji Region and Technical Guidelines for Transition to Clean Energy, after which the guidelines will be promoted through Jing-Jin-Ji and the surrounding areas by air pollution prevention collaborative group.
