State Key Joint Laboratory for Environmental Simulation and Pollution Control, College of Environmental Sciences and Engineering, , HFC-23) is one of the hydrofluorocarbons (HFCs) regulated under the Kyoto Protocol with a global warming potential (GWP) of 14 800 (100-year). China’s past, present, and future HFC-23 emissions are of considerable interest to researchers and policymakers involved in climate change. In this study, we compiled a comprehensive historical inventory (1980–2012) and a projection (2013–2050) of HFC-23 production, abatements, and emissions in China. Results show that HFC-23 production in China increased from 0.08 ± 0.05 Gg/yr in 1980 to 15.4 ± 2.1 Gg/yr (228 ± 31 Tg/yr CO -eq) in 2008 and 2009. Under the examined business-as-usual (BAU) scenario, the cumulative emissions of HFC-23 in China over the period 2013–2050 are projected to be 609 Gg (9015 Tg CO emissions). Currently, China’s annual HFC-23 emissions are much higher than those from the developed countries, while it is estimated that by year 2027, China’s historic contribution to the global atmospheric burden of HFC-23 will have surpassed that of the developed nations under the BAU scenario. Uncertainties of components in assembling an inventory of HFC-23 emissions are shown in Table S1. Individual coproduction ratios of HFC-23/HCFC-22 in China and other countries are presented in Figure S1. Annual amounts of HFC-23 involved in the CDM HFC-23 emission abatement projects are provided in Figure S2. The correlation between the standardized domestic HCFC-22 feedstock production and the standardized GDP in China are shown in Figure S3.

China’s past and future HFC emissions are of great interest because … , HFC-23), with a 100-year global warming potential (GWP) of 12400, is regulated under the Kyoto Protocol. HFC-23 emissions in East Asia, especially in China, are currently thought to represent the majority of global HFC-23 … ) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, SF Recent Trends in Global Emissions of Hydrochlorofluorocarbons and Hydrofluorocarbons: Reflecting on the 2007 Adjustments to the Montreal Protocol Global-scale atmospheric measurements are used to investigate the effectiveness of recent adjustments to production and consumption controls on hydrochlorofluorocarbons (HCFCs) under the Montreal Protocol on Substances that Deplete the Ozone Layer (… Source.
