The climate emergency should have a prominent place in all major social and business decision making processes now. If you’re not worried about the climate risk of decisions you make, you should be worried about future regulatory risk you could be exposed to as climate change forces legislation to change.
F-gas regulations have significantly reduced the GWP of available refrigerants using a combination of outright bans and price increases. This is set to continue under current regulation and, in all likelihood, regulations restricting the use of F-gas (of which synthetic refrigerants are a large part) are going to increase in severity as its use comes under increasing scrutiny.
There are three main aspects to consider here:
-F-gas – draw down continues but also as carbon footprints are reduced the proportion contributed by F-gas rises and will therefore be increasingly important.
-Toxicity – HFOs contain PFAS chemicals which are linked to environmental poisoning and high toxicity for the natural environment and are therefore likely to be subject to regulatory action.
-Availability now and in the future – a heat pump should have a 15 to 20 year life. Installing a high GWP refrigerant heat pump now carries a risk of becoming a stranded asset in the near future.
