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.
A year of avoided emissions, made visible.
GHG emissions ZERO-C avoided over the lifetime of 2024's equipment placed in the market.
ZERO-C · 2024
873,000metric tons of CO₂e avoided.
Over the lifetime of 2024's equipment placed in the market. The comparisons that follow show what that volume actually looks like.
What it adds up to.
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.
Growth
Cumulative avoided CO₂e emissions over the years.
ZERO-C has been ATMO Approved since 2023, now 2 consecutive years of independently verified impact.

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.
