F-gas emissions from leaks from installations decreased after increasing in 2014-2016 in 2017 and 2018. Although emissions increased in 2019, according to the first data for 2020, emissions will reach the lowest value in the observed period. The gradual reduction of emissions from 2016 onwards indicates the successful implementation of measures in this area, which is reflected in the reduction of the amount of supplements for cooling systems and the change in the structure of substances in the direction of substances with lower greenhouse potential. The target value of the indicator from the Operational Programme for Reducing GHG Emissions until 2020 (OP GHG) is only indicative, as there have been several methodological changes since the adoption of the OP GHG. Improvements in the F-gas emissions inventory have shown that past emissions were underestimated during the preparation of the OP GHG, so exceeding the target does not necessarily indicate the non-implementation of measures. In addition, new legislation introducing new measures was adopted at the EU level in 2014.
