Refrigerant regulations and the accompanying HFC phase-down will have—and have already had—far-reaching effects on the cooling industry. The regulations aim to heavily reduce F-gas emissions, which can be achieved in three ways:
Refrigerant leaks are a significant environmental challenge, contributing extensively to greenhouse gas emissions worldwide. In 2019 alone, mobile air conditioning systems released over 420 million tonnes of CO₂-equivalent emissions, with nearly a third of this impact attributed to refrigerant leakage (IEA, 2019). The International Energy Agency (IEA) and the United Nations Environment Programme (UNEP) estimate that better refrigerant management and transitioning to low-global-warming-potential (GWP) refrigerants could prevent up to 460 gigatonnes of CO₂-equivalent emissions over the next 40 years (IEA & UNEP, 2020).
As an HVACR technology and solutions provider, we are committed to designing and producing high-quality components that prevent refrigerant leakage. We also actively support the refrigerant transition by offering a full range of low-GWP refrigerant solutions. Let’s take a closer look at refrigerant lifecycle management and the role installers play in managing refrigerants already in the market.

Depending on geography, different regulations apply. But in general, operators, technicians, and installers in the cooling industry must ensure that the recovery of refrigerants is carried out by certified staff, and the refrigerants are either recycled, reclaimed, or destroyed.
Danfoss supports end-of-life refrigerant recovery, a critical step in responsible refrigerant management. For example, in Australia, only 20% of refrigerant in retiring equipment is successfully reclaimed (Refrigerant Leak Study – A Data-Driven Insight from Australia, 2024, by Refrigerants Australia & Expert Group).
Recovering refrigerant offers several advantages:
The strongest argument for recovery is clearly the environmental one. If refrigerants and the contaminants they contain, such as oil, are properly recovered, they can’t pollute. It’s in all our interests to make sure refrigerant is properly stored and not released into the atmosphere, where it can pollute and potentially harm both the environment and people.
There is an additional safety aspect to refrigerant recovery. Part of the refrigerant transition involves using more low- and ultra-low-GWP refrigerants, which are more flammable than HFCs. When it comes time to decommission equipment containing these refrigerants, it’s critical that they aren’t just vented into the air—where there’s risk they could ignite—but are recovered properly.
As the HFC and HFO phase-down continues, the amount on the market will decrease. This means that the HFC and HFO refrigerants already on the market will increase in value. Every amount of these types of refrigerants you recover can potentially be reused in another installation.
Once the refrigerant is recovered, you have three options: recycle, reclaim, or destroy.
When deciding which option to choose, it’s important to understand that recycled refrigerants are uncertified products, designed to be re-used on-site. If you want to reintroduce the refrigerant into the market, it needs to be reclaimed, where it can be purified, certified (according to the appropriate regulatory standards), and guaranteed by a licensed facility.
Refrigerant recycling primarily focuses on cleaning used refrigerants to make them suitable for reuse within the same system from which they were extracted.
Recycling is a simple cleaning process that removes impurities, moisture, and contaminants. The goal is to restore the refrigerant to its original specifications, so it can be safely reintroduced into the same HVAC or refrigeration system without harming its performance. Recycling is typically done on-site or by service technicians during routine maintenance or system repairs. Recycling aligns with EU circularity goals and is resource effective when done properly.
Benefits:
Reclamation is more complex. It focuses on restoring used refrigerants—e.g., from systems that have been taken out of service—to their original performance standards, but with a broader perspective. The goal is to prepare the refrigerant for reuse in any system, not necessarily the same system from which it was recovered; essentially being used as a brand new refrigerant. This requires specialized equipment and a laboratory analysis to confirm the quality. Reclamation is normally done by dedicated, certified providers with the necessary expertise and infrastructure to carry out the process, who then guarantee the final product. Similarly, the guarantee of the equipment manufacturers is also maintained. Refrigerant reclamation companies can also help with the third option—destruction—for refrigerants that can’t be reused.
Reclaiming used refrigerants aligns with the EU's circular economy action plan, which seeks to reduce waste and keep valuable resources in the EU economy. By recovering and reclaiming refrigerant, you ensure it can be used again, reducing the amount that needs to be produced or imported. You make the most of a valuable—and increasingly rare—resource. And from a business perspective, you ensure the continued use of refrigerants best suited for the equipment or application you’re working with.
Effective refrigerant lifecycle management is dependent on robust leak detection and monitoring, and sensors, such as the DST G-series by Danfoss Sensing Solutions, play a critical role in this process. Sensors enable continuous or periodic monitoring for refrigerant leaks, ensuring that emissions are detected early and can be addressed promptly. This capability is vital during the operational phase, but also relevant at installation, maintenance, and decommissioning.
Sensor-generated data supports compliance with regulations, informs maintenance schedules, and underpins best-practice refrigerant management. From verifying system integrity at installation, to monitoring during operation, to ensuring complete recovery at end-of-life, sensors are essential for minimizing emissions at every stage.
As digitalization and automation increase, sensor data will become even more central to predictive maintenance, automated leak detection, and integrated refrigerant management systems.
Reducing refrigerant leaks isn’t just good for the environment—it’s good for business. With rising refrigerant costs, industry leaders are seeing firsthand how leak reduction and recycling can cut expenses.
