摘要: 我国是全球二氟一氯甲烷(HCFC-22)的主要生产国,在HCFC-22的生产过程中,会产生大量的温室气体——三氟甲烷(HFC-23)。通过分析我国11个HFC-23减排清洁发展机制(CDM)项目的监测数据,确定HFC-23的排放因子,估算我国2000—2010年HFC-23的排放量,并预测了2011—2020年HFC-23的排放量和减排潜力。预计到2020年,我国HFC-23的排放量将达到2.3亿t CO2当量。如果HCFC-22企业能够实现自主减排,那么将为我国2020年CO2排放强度下降40%~45%的减排目标贡献3.2%~3.6%。

Abstract: China is the major producer of chlorodifluoromethane (HCFC-22) in the world. Large amount of fluoroform (HFC-23) was emitted during the production of HCFC-22. Emission factors of HFC-23 were calculated in accordance with the monitoring reports of eleven HFC-23 clean development mechanism (CDM) projects in China and the HFC-23 emissions in 2000-2010 as well as that in 2011-2020 were estimated and projected, respectively. It is expected that, by the end of 2020, emission of HFC-23 in China would be as much as 230 million t CO2 equivalent. If HCFC-22 producers could voluntarily reduce HFC-23 emissions, it will contribute 3.2%-3.6% to the national CO2 emission reduction target for 2020.

Key words: greenhouse gas, HFC-23, emission reduction potential
