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.

GHG emissions Zudek avoided over the lifetime of 2021'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.
