Drawdown: the most comprehensive plan ever devised to reverse global warming
is a review not just of green energy sources but all the other human activities that effect our carbon footprint. This includes building design, transport efficiency, recycling, population control and food use. A total of 80 actions are analysed for their potential to reduce carbon emissions.
I found the number one concern surprising – refrigeration. The coolants that refrigerators use are hydrofluorocarbons(HFCs). Their capacity to warm the atmosphere is one to nine thousand times greater than carbon dioxide. An international agreement (the Kigali accord) is in hand to phase out HFCs by 2028. However, in the meantime disposal of old refrigerator units represents a great threat to global warming and the process of safe disposal is expensive.
Surely this is one area where the polluter ought to pay. Refrigerator manufacturers should have to receive and recycle old fridges. Refrigerator costs will rise but we will all be better off.
