  • 摘要:面对国家碳达峰、碳中和战略目标,“十四五”时期,北京市提出推进大气污染物和温室气体排放协同控制,因此,开展协同控制效果评估对于持续改善空气质量和减少碳排放具有重要意义.本研究在减排措施筛选和减排量测算的基础上,分析了主要大气污染物和CO2的减排潜力,采用协同控制效应坐标系法、协同控制交叉弹性分析法和协同评估指数法,对减排措施主要大气污染物SO2、NOx、PM10、VOCs和温室气体CO2的协同控制效果进行评估.结果表明,减排措施对于SO2、NOx的减排潜力均在20%以上,对于CO2的减排潜力约为7%.各项措施对NOx、PM10、VOCs和CO2排放具有协同控制效果.从坐标系法和评估指数法分析结果来看,浅山区煤改清洁能源和压减本地火力发电量对SO2和CO2的协同控制效果较好,而推广新能源车对NOx、PM10、VOCs和CO2的协同控制效应为最佳;从交叉弹性分析法结果来看,推广超低能耗建筑、推广可再生能源供热、推广节能燃气壁挂炉、淘汰更新高排放车辆和降低机动车使用强可等比例减少SO2和CO2排放、NOx和CO2排放或PM10和CO2排放,措施协同程度较高.分别从开展全生命周期评估研究、规范评估方法、拓宽研究领域和区域的角度提出协同控制相关建议,以期为协同控制后续的研究提供方向借鉴,并为北京市大气污染物和温室气体协同控制工作提供技术支撑.
  • Abstract:It is significance to carry out co-control effects assessment for improving air quality and reducing carbon emissions under the national strategic objectives of carbon peaking and carbon neutrality. In this study, the co-control effects coordinate system, co-control cross-elasticity analysis and synergy evaluation index methods are used to evaluate the benefits of co-control for SO2, NOx, PM10, VOCs and CO2 base on emission reduction measures screening and emission reduction calculation. The results show that the emission reduction potential of SO2 and NOx is more than 20%, and the emission reduction potential of CO2 is about 7%. All the emission reduction measures are able to achieve co-reduction of NOx, PM10, VOCs and CO2 emissions. The analytical results of co-control effects coordinate system and synergy evaluation index analysis show that replacing coal-fired with clean energy and reducing local thermal power generation obtain the higher co-benefits of SO2 and CO2, and promoting new energy vehicles has the highest co-benefits of NOx, PM10, VOCs and CO2; the analytical results of co-control cross-elasticity analysis shows that promoting ultra-low energy buildings, renewable energy for heating, energy-saving gas wall hanging furnace, phasing out and upgrading high-emission vehicles and reducing vehicle use intensity could reduce SO2 and CO2 emissions equally or NOx and CO2 emissions equally or PM10 and CO2 emissions equally, with a high degree of coordination. Therefore, the co-control suggestions from the perspectives of life cycle assessment investigation has been proposed which could provide reference for the future research of co-control and the technical support for the management decision of air pollution control and low carbon development in Beijing.
