Why this matters

Most refrigeration runs on chemicals that warm the planet, or quietly poison it.

HFCs warm the atmosphere up to 14,000× more than CO₂. Their HFO replacements break down into TFA, a forever chemical now detectable in rain, ice, and human blood.

The answer

CO₂, ammonia, hydrocarbons. Proven for over a century. They don't warm the planet, and they don't leave a forever chemical behind.

Natural refrigerants avoid both.

Primary metric

A year of avoided emissions, made visible.

GHG emissions Vahterus avoided over the lifetime of 2024's equipment placed in the market.

Hidden pollutant

TFA: the forever chemical you haven't heard of.

Trifluoroacetic acid is an ultra-short-chain PFAS that forms as a breakdown product of synthetic refrigerants and accumulates in rainwater. Natural refrigerants don't break down into TFA.

Stage 1 · Emission

HFCs and HFOs leak from refrigeration systems.

Synthetic refrigerants escape over the lifetime of every system: installation, service, end-of-life. The leaks are small, but they add up across millions of installations worldwide.
