The amount of harm from refrigerants, the chemicals used in cooling systems to move heat around, is vastly underappreciated so its good to see it mentioned.
"HFCs trap between 1,000 and 9,000 times as much heat as the same amount of CO2, meaning they are much more potent causes of global warming. On this basis, Paul Hawken of Project Drawdown, a think-tank, calculates that improving air-conditioners could do more than anything else to reduce greenhouse gases."
- Tharkun 8y agoThere are heat pumps which use CO2 as their refrigerant. Apparently they are more efficient (and less potentially hazardous for people and climate) than most alternatives.
- thinkcontext 8y agoFrom what I've seen it's used in water heater heat pumps, not space heating and cooling. Perhaps with tighter regulations on HFCs CO2 will be more widely used.
