北京试点碳市场行业基准值研究——以供热行业为例

以北京试点碳市场的供热行业为例开展行业基准值研究,基于2013～2019年碳试点经核查的热力重点排放企业数据,采取4种基准线情景对北京市热力行业碳排放基准值进行分析,结果表明:随着北京市大气污染治理措施推进,供热行业燃煤清洁化改造基本完成,以2017年为分水岭,供热强度由快速下降过渡到平稳状态,适宜选择更近的历史年份作为分析的基准年,经综合评估基准线数值的先进性,行业配额的盈余程度和配额不足企业比例,建议北京市供热行业基准值取值为63.1kgCO₂/GJ,该基准值比已发布的北京市地方行业能耗限额标准严格,与已发布的北京市供热行业碳排放先进值具有较好一致性;北京市热力行业从历史强度法转变为基准线法后,通过划定统一的基准线,令行业整体配额处于不足状态,公平性相比历史强度法进一步提高,对实现全市双碳目标下热力系统重构具有积极促进作用.

Industry benchmark research of Beijing carbon trade pilot: A case study in thermal industry

This paper took carbon emissions industry benchmark of heating industry in Beijing pilot carbon market as an example. Based on the verified enterprises data of the heating industry from 2013 to 2019, this study analysed 4kinds of benchmark scenarios. Following the Beijing atmospheric pollution control, the clean transformation of the coal-fired heating industry was basically completed. Taking 2017 as the turning point, the heating intensity was transitioned from a rapid decline to a stable state, and it was appropriate to choose a more recent historical year as the base year for analysis. The benchmark value of the heating industry in Beijing should be set as 63.1kgCO₂/GJ after assessing the advancement of comprehensive evaluation benchmark value and comparing the proportion of the industry degree of surplus quota and quota insufficient enterprise. This benchmark value in this research was stricter than the published energy consumption limit standard for local heating industries in Beijing, and it was in good agreement with the published advanced carbon emission value of the Beijing heating industry. After the transformation of the heating industry in Beijing from the historical intensity method to the benchmark method, the fairness of this method was further improved compared with the historical intensity method, by drawing a uniform baseline and making the overall quota of the industry inadequate. This study has a positive role in promoting the reconstruction of thermal system under the urban carbon neutrality target.
