Establishment of HCFC-22 National–Provincial–Gridded Emission Inventories in China and the Analysis of Emission Reduction Potential

Abstract: Due to chlorodifluoromethane’s (CHClF2, HCFC-22) dual environmental impact on climate change and ozone depletion, its emissions have attracted international attention. In this study, a set of national–provincial–gridded (1° × 1°) emission estimation methods were built and applied to obtain the national, provincial, and gridded emission inventories in China in 1990–2019. In addition, the HCFC-22 emission reduction potential of different emission scenarios was analyzed. The results show that China’s HCFC-22 emis… Show more

“…Emissions of HCFCs derived using the tracer ratio method in this study compared with the reported estimates for northern China. 6,13,22,26,32,53,54 For example, the emissions of HCFC-141b and HCFC-142b from northern China in 2020− 2021 were 120 and 98% higher than those in 2019, respectively, as estimated by Yi et al 13 Although the reason for the increase is not clear, it may be attributed to the large amount of bank emissions that occur when an appliance reaches the end of its service life or the unreported HCFC production for dispersive uses. 55 Thus, it is necessary to further inspect and verify the actual productions and consumptions of HCFCs to explain the emission increase.…”

“…During 2015–2020, the HFC consumption in the MAC sector was stable, while the emissions continued to increase. Due to the “delay in emission” of the sectors covered, HFCs were stored in appliances as banks, leading to emissions of HFCs lagging behind the corresponding consumption. , In this study, HFC-134a made the largest contribution to the total HFC emissions (65%), and the MAC, CAC, and PU sectors accounted for 69%, 30%, and 1% of the cumulative HFC-134a emissions in 2000–2020, respectively.…”
