Unchecked. The fluorochemical industry's scandalous HFC-23 by-product emissions amid the climate crisis.

Author(s) : EIA

Type of monograph: Report

Summary

Emissions of HFC-23, a potent greenhouse gas, reached a record high of 17,300 tonnes/year in 2019, equivalent to more than a quarter of a billion tonnes of carbon dioxide equivalent (254 MtCO2e). Since 2020, the Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer has required Parties to capture and destroy HFC-23, which is primarily produced and emitted as an unwanted by-product of HCFC-22, an ozone-depleting substance (ODS) controlled by the Montreal Protocol.
Although emissions decreased from 2019-22, they remain higher than anticipated, underscoring ongoing compliance issues and the need for effective monitoring and regulation of the fluorochemical industry. Cumulative HFC-23 emissions since the adoption of the Kigali Amendment in 2016 are almost 106,000 tonnes, equivalent to 1.56 billion tonnes of CO2. A strong response from the Parties to the Montreal Protocol is required.
