Fenagy — Impact report 2024

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 Fenagy avoided over the lifetime of 2023'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.

166k

homes / year

powered for a year on the same footprint

293k

petrol cars off the road

for one year of driving emissions avoided

5.4B

km not driven

distance equivalent never burned in a tank

Growth

Cumulative avoided CO₂e emissions over the years.

Fenagy has been ATMO Approved since 2022 — 2 consecutive years of independently verified impact.
