HCFC-142b emission inventory in North China plain and environmental impact analysis
The North China plain was selected as research region,the emission factor method was used to establish the HCFC-142b emission inventory from 2000 to 2060,its spatial distribution characteristics were discussed,and the sensitivity analysis of emission results was carried out for different sectors.The results showed that the cumulative emissions of HCFC-142b from 2000 to 2019 were 34.0kt in this region.Jiangsu,Shandong and Henan had the largest emissions,with cumulative emissions of 595.1t,267.6t and 196.5t,respectively.Emissions from XPS was largest,followed by ICR.The most sensitive factors were initial emission factor and equipment disposed rate in XPS and ICR sector,respectively.The projected emissions show that under the control of the Montreal Protocol,the cumulative emission reduction potential of North China will reach 151.9kt(9.9kt CFC-11-eq;350.9mt CO2-eq)from 2020 to 2060.
