Environmental Impact

Cutting Greenhouse Gas Emissions

A2L refrigerants are doing wonders for our planet by slashing greenhouse gas emissions. What’s extra cool is their lower Global Warming Potential (GWP) compared to the usual Hydrofluorocarbons (HFCs). The United States made that a goal when it signed the Kigali Agreement in September 2022. The aim? To ditch HFCs and cut their use by a whopping 80-85% by the 2040s in developed countries.

Now get this—the EPA’s HFC Allocation Program could chop off as much as 4.6 billion metric tons of carbon dioxide from 2022 to 2050. That’s like wiping out three whole years’ worth of emissions from the entire U.S. power sector as of 2019. If we phase out HFCs globally, we might dodge up to 0.5°C of global warming by 2100.

Year Range	Projected Emission Reduction (Billion Metric Tons CO2)	Equivalent Power Sector Emissions (Years)
2022-2050	4.6	3

The Role of A2L in Phasing Out HFCs

A2L refrigerants are the real MVPs in reducing HFCs. Thanks to the American Innovation & Manufacturing (AIM) Act of 2020, the EPA set a rule to cut HFCs by 85% over the next 15 years. This plan should prevent 900 million metric tons of CO2-equivalent emissions by 2035 and could shave off up to 0.5°C of warming by 2100 (ICC).

It’s not just about the planet; it’s also about the wallet. The EPA says we could see net benefits of $269.9 billion from 2022 through 2050. These benefits include climate advantages worth up to $50.4 billion in today’s cash.

And there’s more—the EPA has another rule in the pipeline for emission reduction and reclamation, expected to prevent about 142 million metric tons of CO2-equivalent in HFC emissions between 2025 and 2050. This move could save us at least $6.1 billion over that period (EPA).
