What Is the R404A Phase-Down?
The Australian Government is gradually reducing the import quota of high-GWP (Global Warming Potential) HFC refrigerants to cut emissions and encourage the transition to more environmentally sustainable refrigeration solutions. It is estimated that R404A imports will be reduced by 85%, making it crucial for businesses to plan for alternative refrigerants.
- R404A supply constraints are now being observed in the market.
- The 2026 import quota reduction has now come into effect, with total refrigerant imports decreasing and further reductions scheduled.
To better understand the potential impact on stores in Australia, we reviewed availability across several suppliers for both R404A and its commonly used retrofit alternatives, R448A and R452A.
Future-Proofing Supermarkets: Moving Beyond R404A with Confidence
The good news? There are clear and proven paths forward.
Step 1: Audit Your Current System Identify where R404A is still in use and assess system condition. Leak checks are now a regulatory requirement and with rising gas prices, they’re more critical than ever.
Step 2: Choose the Right Replacement Path Short-term retrofits like R448A or R452A may be viable. But long-term, CO₂ is the gold standard. It’s natural and future-proof with a GWP of just 1.
Step 3: Don’t Wait for Breakdown Upgrades should be planned proactively to avoid emergency replacements. CO₂ is already used successfully across Australian supermarkets – from independent stores to national chains – and is now viable even for smaller footprints.
