Government environmental control measures on CO2 emission during the 2014 Youth Olympic Games in Nanjing:Perspectives from a top-down approach
文献摘要：
Strict air pollution control measures were conducted during the Youth Olympic Games(YOG) period at Nanjing city and surrounding areas in August 2014.This event provides a unique chance to evaluate the effect of government control measures on regional atmo-spheric pollution and greenhouse gas emissions.Many previous studies have observed sig-nificant reductions of atmospheric pollution species and improvement in air quality,while no study has quantified its synergism on anthropogenic CO2 emissions,which can be co-reduced with air pollutants.To better understand to what extent these pollution control measures have reduced anthropogenic CO2 emissions,we conducted atmospheric CO2 mea-surements at the suburban site in Nanjing city from 1st July to 30th September 2014 and 1st August to 31st August 2015,obvious decrease in atmospheric CO2 was observed between YOG and the rest period.By coupling the a prioriemission inventory with atmospheric trans-port model,we applied the scale factor Bayesian inversion approach to derive the posteri-oriCO2 emissions in YOG period and regular period.Results indicate CO2 emissions from power industry decreased by 45％,and other categories also decreased by 16％ for manu-facturing combusting,and 37％ for non-metallic mineral production.Monthly total anthro-pogenic CO2 emissions were 9.8 (±3.6) × 109 kg/month CO2 for regular period and decreased to 6.2 (±1.9) × 109 kg/month during the YOG period in Nanjing city,with a 36.7％ reduc-tion.When scaling up to whole Jiangsu Province,anthropogenic CO2 emissions were 7.1 (±2.4) × 1010 kg/month CO2 for regular period and decreased to 4.4 (±1.2) × 1010 kg/month CO2 during the YOG period,yielding a 38.0％ reduction.
