OPINION: Your air conditioner could heat the planet 1,000s of times more than CO2, but these appliances can reduce the emission by up to 1,000%, writes Mary Grady, executive director of American Carbon Registry.

Recent heatwaves have led to thousands of deaths and captured headlines as we enter a dangerous new era of extreme heat contributing to dangerous wildfires and harming agriculture production. Yet, one of the quickest and most sought-after solutions to deal with extreme temperature, air conditioners, could rapidly increase global warming.

HFCs are a major climate concern due to their high global warming potential . GWP is a measure of the warming potential of 1 ton of a gas, once emitted into the atmosphere, relative to 1 ton of carbon dioxide in a given period of time. These high-GWP substances are also found within foam insulation and refrigeration appliances, which will also be increasingly called upon with extreme temperatures. These substances have been leaking for decades,contributing to nearly 10% of global warming emissions. It is expected their emissions will rise by a staggering 90% from 2017 levels by 2050. Introducing billions of more appliances over the next decade could easily push current climate goals out of reach.
