The automotive industry is undergoing a major transformation in its thermal energy management, as regulatory restrictions on PFAS tighten under the EU Reach framework. Earlier used in mobile air conditioning systems, traditional fluorinated refrigerants are becoming increasingly out of alignment with both long-term sustainability goals and regulatory expectations. As a result, natural refrigerants, especially those based on CO2, are being considered the most viable option for future growth. In addition to being compliant with regulations, natural refrigerants provide an opportunity for Original Equipment Manufacturers (OEM’s) to protect their vehicles from future regulations, reduce their risk of being subject to new regulations, and align themselves with the European Union’s overall climate and circular economy objectives.
The Real Challenges Behind Adopting Natural Refrigerants
Although momentum continues to build toward using natural refrigerants instead of fluorinated refrigerants, numerous technological, regulatory, and commercial issues remain. CO2-based refrigerants require higher operating pressures than traditional fluorinated refrigerants, necessitating different design features in OEM components and tighter integration between systems, raising questions about manufacturing costs, performance, and scalability. In addition, inconsistent enforcement of regulations across European nations creates uncertainty about the timeline for adopting new refrigerant technologies. Additional challenges include differences in supplier capabilities, each country’s infrastructure readiness, and internal engineering maturity, which could delay investment and implementation of natural refrigerants.
Strategic Pathways to Unlock Adoption and Market Advantage
Forward-looking companies are striving to develop their natural refrigerant initiatives by prioritizing regulation-based market segments over broad technology rollouts. Targeting high-impact vehicle segments, aligning development roadmaps with regulatory timelines, and focusing on regions with stronger OEM concentration and market readiness can significantly improve outcomes. Tracking competitor activity, pilot deployments, and partnership models helps sharpen positioning and avoid crowded bets. A phased approach that includes focused R&D, early collaboration with OEMs, and use-case-driven deployment will enable a company to develop a structured growth opportunity from regulatory pressure, rather than being reactive.
