With this paper, Eurovent provides its feedback following the online stakeholder workshop for the revision of the F-Gas Regulation, held by DG CLIMA on 06 May 2021. In short, the proposed modelling presents a serious lack of granularity, does not consider the current state-of-the-art nor future technological trends, and does not consider the barriers related to safety standards, European Union legislation, and building codes. The potential future share of F-gases in new equipment must therefore be reassessed and the future policy options must be revised accordingly.
