Description:

Trichlorofluoromethane (CFC-11, CFCl 3) is a major anthropogenic ozone-depleting substance and greenhouse gas, and its production and consumption are controlled under the Montreal Protocol. However, recent studies show that CFC-11 emissions increased during 2014–2017 relative to 2008–2012. In this study, we use a chemistry-climate model to investigate the stratospheric impacts of potential CFC-11 emissions continuing into the future. As a sensitivity test, we use a high CFC-11 scenario in which the inferred 2013–2016 average emissions of 72.5 Gg/yr is sustained to year 2100. This increases equivalent effective stratospheric chlorine by 15% in 2100, relative to the WMO (2018) baseline scenario
