Emissions of carbon tetrafluoride CF₄, NF₃ and CHF₃ in east Asia have been calculated using atmospheric measurements and an atmospheric transport model. We calculate emissions of CF₄ to be quite constant between the years 2008 and 2015 for both China and South Korea, with 2015 emissions calculated at 4.33 ± 2.65 Gg yr^-1 and 0.36 ± 0.11 Gg yr^-1, respectively. Emission estimates of NF₃ from South Korea could be made with relatively small uncertainty at 0.6 ± 0.07 Gg yr^-1 in 2015.
