In northern countries with lower ambient temperatures, remote CO2 solutions are often more sustainable and provide higher energy efficiency. BAN ON HIGH GWP REFRIGERANTS From 1st January 2020 the EU F-gas regulation bans the sale of new refrigeration equipment that use F-gasses with a Global Warming Potential (GWP) of 2500 or above. The next phase down that takes effect 1st January 2022 bans refrigerants with a GWP above 150.
