A project has begun in New Zealand for the refrigerants industry to tackle one of the most potent, but least known causes of climate change.The gases used in refrigerants – perfluorocarbons (PFC) and hydrofluorocarbons (HFC) – are rated among the most effective at trapping heat in the earth’s atmosphere; thousands of times more potent than carbon dioxide with respect to their global warming potential, says sustainability expert Darren Patterson. This, combined with their widespread use, makes them a high priority target for tackling climate change worldwide, he says.
