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.
02
Primary metric
A year of avoided emissions, made visible.
GHG emissions Fenagy avoided over the lifetime of 2025'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.
In real-world terms
What it adds up to.
70k
homes / year
powered for a year on the same footprint
121k
petrol cars off the road
for one year of driving emissions avoided
2.2B
km not driven
distance equivalent never burned in a tank
03
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.

Growth
Cumulative avoided CO₂e emissions over the years.
Fenagy has been ATMO Approved since 2023 — 4 consecutive years of independently verified impact.

The company
Fenagy: company profile.
Fenagy is a leading manufacturer of industrial heat pumps and refrigeration systems, and their vision is to help the transformation of the energy system into a greener and more sustainable one. The company has two focus areas: the district heating sector, where its electrical heat pumps prevent the burning of fossil fuels, and the industry, where its combined heating and cooling systems can reuse all waste energy. Fenagy’s systems only use the natural refrigerants CO2 and hydrocarbons, and with these, they cover a broad range of applications.
