摘要
CO_(2)排放清单是推动城市低碳发展的重要基础工作。文中采用自下而上和自上而下相结合的方法测算了2017年北京市CO_(2)排放清单。自下而上方面,基于近13000座锅炉数据核算了CO_(2)排放量。自上而下方面,利用改编后的北京市分行业分品种能源消费表对自下而上核算的分行业能源消费数据进行校验,从宏观上控制核算数据的系统误差。研究发现,尽管实施了去煤化一系列政策,北京市中心城区仍然是碳排放最密集、强度最大的区域。北京市制定下一阶段的低碳发展政策,需更加重视控制道路交通、商业楼宇和居民生活产生的碳排放。
Different from the traditional bottom-up approach,a combination of bottom-up and top-down methods was used to measure the Beijing high spatial resolution CO_(2) emission inventory.From the bottom-up approach,based on the data of nearly 13000 facilities(power station boilers,industrial kilns,heating boilers),the fossil energy consumption and carbon dioxide emissions of fixed sources were calculated.From the top-down approach,the energy consumption of boilers in different industries were verified using the energy consumption sheet by sectors,thus the systematic errors of the emission inventory were controlled at a macro level.It’s found that the central urban area was still the region with the highest carbon density and intensity.To formulate a low-carbon policy for the next stage,Beijing needs to pay more attention to carbon emissions from road traffic,commercial buildings and residents’lives.
