Producers, Importers and Exporters of F-gases must report annually to the European Commission the production, imports and exports of F-gases, as well as the quantities recovered, recylced and destroyed. They must also identify sales in the main categories of applications:
The problem is that the same substance can be used in a variety of applications, so it will be difficult to be 100% accurate.
If you purchase or sell more than 1 tonne of F-gases in for example Switzerland, Norway, Ukraine or Turkey, then you will be considered an importer/exporter.
The reporting requirements are only mandatory for trade in the substances, equipment containing F-gases are exempted.
