A2L Refrigerant Market Projected to Reach $5.92 Billion by 2031
Key Facts
- The market is expected to grow at a CAGR of 8.1% from 2026 to 2031, reaching nearly $6 billion.
- Increasing adoption of low-GWP refrigerants like R-32 and R-454B in HVAC, refrigeration, and automotive applications is a key driver.
- Growing demand for A2L-compatible components, leak detection, and handling technologies supports industry expansion.
DELRAY BEACH, Florida — The global A2L refrigerant market is projected to grow from $4.02 billion in 2026 to $5.92 billion by 2031, according to a MarketsandMarkets report.
The market is expected to grow at a compound annual growth rate of 8.1% during the forecast period. The report attributes the growth to increasing demand for lower-global-warming-potential refrigerants as governments, original equipment manufacturers, and end users transition away from higher-GWP hydrofluorocarbons.
A2L refrigerants are gaining adoption across air conditioning, refrigeration, heat pumps, chillers, and automotive applications. R-32 is gaining adoption in residential and commercial air conditioning, while R-454B is increasingly being used as a lower-GWP alternative to R-410A in HVAC systems.
R-454B is expected to be the second-fastest-growing A2L refrigerant during the forecast period. MarketsandMarkets attributes that growth to demand for lower-GWP refrigerants in residential and commercial air conditioning and heat pump applications.
Air conditioning is projected to be the fastest-growing application segment. The residential segment is also expected to record the highest growth by end-use industry.
The report also points to growing demand for A2L-compatible equipment, components, charging systems, leak-detection technologies, and technician-handling capabilities. Because A2L refrigerants are mildly flammable, regulatory requirements and safety standards are influencing equipment design, installation, servicing, and technician training.
Heat pumps, data center cooling, commercial refrigeration upgrades, and replacement of aging HVAC equipment are also identified as sources of A2L refrigerant demand.
By region, Asia Pacific accounted for 47% of the A2L refrigerants market in 2025. The region is also expected to be the second-fastest-growing market during the forecast period.
MarketsandMarkets identified Chemours, Solstice Advanced Materials, Dongyue Group, Arkema, and Daikin Chemicals among the leading players in the A2L refrigerants market.
The report projects continued growth as the HVAC and refrigeration industry shifts toward lower-GWP refrigerants and equipment designed around new refrigerant requirements.
