The Global Refrigerant Transition Is Accelerating — Here’s What Australian Businesses Need to Know

The way we cool food is changing — and changing fast. Around the world, major retailers, food producers, and hospitality operators are moving away from traditional high global warming potential (GWP) refrigerants like hydrofluorocarbons (HFCs) toward more environmentally responsible alternatives. In the United States, discount supermarket giant Aldi has been singled out by the Environmental Investigation Agency (EIA) as a leader in this transition, making significant strides in phasing out HFC-based refrigeration systems across its store network.

While that story is unfolding in America, it carries a very clear message for businesses right here in Australia: the refrigerant transition is not a future problem. It is a present reality. Whether you run a busy café in Melbourne, a pub in Brisbane, a supermarket in Perth, or a food production facility in regional New South Wales, the refrigerants powering your cold rooms, display cases, and commercial fridges are increasingly coming under scrutiny — from regulators, from sustainability-conscious customers, and from your own bottom line.

Understanding where the industry is heading, and what steps you can take now to stay ahead of the curve, could save your business a significant amount of money, reduce your environmental footprint, and ensure you’re not caught scrambling when regulatory deadlines hit. Let’s break it all down.

What Are HFCs and Why Are They Being Phased Out?

Hydrofluorocarbons — better known as HFCs — became the go-to refrigerant for commercial and industrial cooling systems after the phase-out of ozone-depleting substances like CFCs and HCFCs in the late 1980s and 1990s. At the time, they were considered a safer, more environmentally friendly alternative. The problem? We now know that while HFCs don’t damage the ozone layer, they are extremely potent greenhouse gases. Some common HFC refrigerants have global warming potential values hundreds or even thousands of times greater than carbon dioxide.

For context, one of the most widely used HFC refrigerants — R-404A — has a GWP of approximately 3,922. That means one kilogram of R-404A leaking into the atmosphere has the same warming effect as nearly 4,000 kilograms of CO2. For a typical commercial refrigeration system, even small leaks add up to a substantial environmental impact over time. It’s a sobering figure, and it goes a long way toward explaining why governments and international bodies have been working to restrict and ultimately phase down HFCs globally.

The Kigali Amendment to the Montreal Protocol, which Australia ratified, commits signatory nations to a significant phase-down of HFC consumption. In practical terms, this means the availability of high-GWP HFC refrigerants will continue to decline, and their cost will continue to rise as supply tightens. Businesses still relying heavily on HFC-based systems should be planning their transition strategy now rather than waiting until they have no choice.

Australia’s Regulatory Landscape for Refrigerants

Australia has been progressively tightening its regulations around synthetic refrigerants through the Ozone Protection and Synthetic Greenhouse Gas Management Act and its associated regulations. The Australian Government’s phase-down schedule for HFCs is structured to reduce consumption significantly over the coming years, aligning with our international commitments under the Kigali Amendment.

For Australian businesses, this translates into a few very practical realities. Firstly, the cost of servicing and recharging HFC-based systems is already rising, and this trend is expected to continue. As the supply of high-GWP refrigerants decreases in line with phase-down quotas, the price per kilogram climbs. Businesses that have ageing HFC systems and are regularly topping them up due to leaks are already feeling this pinch — and it will only get worse before it gets better.

Secondly, Australian regulations require that anyone handling refrigerants holds the appropriate ARCtick licence, and that equipment containing certain amounts of refrigerant is subject to regular leak checks. Compliance obligations are real
