Chemours Backs Automotive Industry's Call for Extended Transition Period

The Chemours Company (NYSE: CC), a leading global chemical firm, has declared its support for the automotive sector's demand for a prolonged transition period concerning fluorinated gases (F-gases) in mobile air conditioning units (MAC). This transition period is pertinent to the new PFAS restrictions proposed by the European Union.

During a public consultation process, various industry organizations, including the European Automobile Manufacturers Association (ACEA), the Japan Automobile Manufacturers Association (JAMA), and the German Association of the Automotive Industry (VDA), highlighted the necessity of extending the transition framework. They argue for a transition period of at least 13 years for light electric vehicles and 20 years for other vehicle types. A critical reason provided was the absence of a direct substitute for the current refrigerant used in MAC, R-1234yf.

Joseph Martinko, president of Chemours' Thermal & Specialized Solutions division, reinforced the company's backing, stating, “Chemours supports representatives from the entire automotive value chain in their demand for a practical, scientifically-based timeline for transitioning vehicle air conditioning systems to ensure consumers have access to safe, efficient, and sustainable vehicle cooling.”

Martinko elaborated on the complex nature of this transition, citing that the development, validation, integration, and large-scale implementation of next-generation refrigerant solutions need significant time. For context, the last major refrigerant shift, from R-134a to R-1234yf — a nearly direct substitute — spanned over 15 years. Therefore, a minimum 13-year exemption aligns with the reality of such a multifaceted transition.

Currently, only two PFAS-free refrigerants, propane (R-290) and CO₂ (R-744), are being evaluated for MAC applications. However, significant hurdles remain. For instance, propane, while a viable option, presents substantial safety concerns due to its high flammability and regulatory barriers in key markets, including the U.S. These challenges necessitate new system designs, safety protocols, validation procedures, and manufacturing adjustments before a broader application of propane could be feasible.

Likewise, the CO₂ systems require completely different system architectures and high-pressure components, especially in warmer climates. This may increase energy consumption, reduce vehicle range, and elevate production costs and complexities, as noted by the German Association of the Automotive Industry. Each alternative would necessitate comprehensive redesign and validation cycles, indicating they are not “drop-in” solutions but instead critically influence system architecture, vehicle integration, safety requirements, and overall system performance.

Taken together, these technical, safety-related, regulatory, and manufacturing considerations underline the need for an extended transition period that aligns with the automotive industry's design, validation, and production cycles.

Moreover, the automotive industry has identified practical measures to be pursued during the exemption period to further reduce emissions. A report released earlier this year by a technical working group highlighted that incremental emissions control measures, including maximum leakage rates, mandatory inspections, and refrigerant recovery protocols, could lead to a potential reduction of up to 60% in annual emissions.

Chemours is committed to continuing its collaboration across the automotive value chain to advance low-emission, high-performance cooling solutions. Through its Opteon™ portfolio and ongoing investments in refrigerant innovation, the company supports solutions that meet the evolving demands of the automotive sector while promoting European objectives concerning climate, safety, and mobility.
