Based on historical HFCs consumption in each sector, here we estimated historical HFCs emissions with a bottom-up method, and projected the consumption baseline and schedule for HFCs phase-down in China under the KA and the corresponding potential for emission reduction. Results showed that China's HFCs consumption and emissions in 2017 were 164,000 t (311 Mt C 2_eq) and 108 Mt C02-eq, respectively. HFCs consumption baseline was projected to be (724 ± 18) Mt C 2-eq in 2024, and China should take measures to phase-down HFCs by 2029, at the latest, to meet the requirements of the KA. HFCs consumption in 2050 under KA would reach the level of 2012 2013. Cumulative reduced consumption was estimated at 10.8 (10.1 11.6) Gt C 02-eq, and cumulative reduced emissions were estimated at 5.38 (4.90 5.64) Gt C 02-eq by 2050.展开更多
