Note: Iceland entered the ETS in 2013; skipped earlier data. ETS data for Aluminium plants also contains PFC emissions, which can't be calculated exactly from the Industrial Emissions Portal data. This explains the slight deviation from 2013 to 2018 (but not the much larger deviation from 2019 to 2022).

Note: The Industrial Emissions Portal reports a large release of SF₆ in 2011, but not in any other year.


Solvay SF₆ plant (Bad Wimpfen, Germany)

Emissions before 2011 where much higher, skipped them to keep plot readable.
