The implementing Regulations of the original Regulation remain in force and continue to apply until new acts are adopted.The current Regulation strengthened the previous measures and introduced far-reaching changes by: 1. Limiting the total amount of the most important F-gases that can be sold in the EU from 2015 onwards and phasing them down in steps to one-fifth of 2014...
