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 EQUANS Kältetechnik avoided over the lifetime of 2024's equipment.
Stage 1 · Scale check
1 metric ton of CO₂e is an 8-meter cube.
A petrol car emits roughly that much in six months.
What it adds up to.
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.
Growth
Cumulative avoided CO₂e emissions over the years.
EQUANS Kältetechnik has been ATMO Approved since 2023 — 2 consecutive years of independently verified impact.

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.
