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 Enns Refrigeration 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.
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.
Enns Refrigeration has been ATMO Approved since 2025 — 2 consecutive years of independently verified impact.

This system has effectively supported our operations for the past 1.5 years and continues to meet our expectations. It is recognized for its safety and high energy efficiency. While it is still too early to provide a comprehensive review - given Canada’s diverse climatic conditions - the system has generally performed well, delivering great outputs.
I would rate the equipment 4 out of 5. Unlike other systems, it requires some time to adjust to operational changes, demand fluctuations, and external factors. As a result, we have occasionally observed alerts, which may be due to initial bugs or system adjustments. Importantly, no breakdowns or recurring issues have been observed.
Yes, the supplier complies with all applicable safety requirements, ensuring that both the system and its products are safe to operate. The system is continuously monitored for alerts and major issues, with minimal response time to resolve any problems, supporting smooth operations and maintaining safety.
