Accelerating Clean Cooling & Heating

01

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.

Hidden pollutant

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

Trifluoroacetic acid is an ultra-short-chain PFAS that leaks from synthetic refrigerants and accumulates in rainwater. Natural-refrigerant systems leak zero.

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.

Become ATMO Approved

Does your company use natural refrigerants?

The ATMO Approved label is independently verified — not self-declared, not marketing. If your equipment runs on CO₂, ammonia, hydrocarbons, or water, you may qualify.
