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 SRT avoided over the lifetime of 2025's equipment placed in the market.
SRT · 2025
43,200metric tons of CO₂e avoided.
Over the lifetime of 2025'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.
In the words of the people who built it.
SRT wants to become ATMO Approved because we share the same principles of sustainability and care for the planet, prioritizing the use of natural refrigerants and energy efficiency in all our projects.
