Global Adoption Trends: Why the World Is Choosing R-32
As the HVAC industry pivots toward low-GWP refrigerants, a clear global pattern has emerged—R-32 is rapidly becoming the preferred A2L refrigerant. From Asia to Europe and now gaining traction in North America, R-32’s combination of efficiency, serviceability, and moderate GWP makes it the dominant choice in residential and light commercial applications. This article explores why the world is choosing R-32, the countries leading the transition, and what this trend means for the future of HVAC systems.
The Global Refrigerant Transition at a Glance
Driven by international climate agreements such as the Kigali Amendment to the Montreal Protocol, nations around the world have committed to phasing down high-GWP refrigerants like R-410A. This has led to the accelerated adoption of A2L refrigerants with lower global warming potential.
R-32 stands out as a front-runner because of its:
-
GWP of 675 (vs. 2,088 for R-410A)
-
High energy efficiency
-
Established safety profile and service track record
Asia Leads the Way
Japan: The Birthplace of R-32 Adoption
Japan was the first country to widely adopt R-32, beginning in 2012 with Daikin’s split system AC units. According to Daikin Global, over 10 million units using R-32 had been sold in Japan within the first few years, setting a global precedent.
India and Southeast Asia
Energy efficiency programs across India, Thailand, and Malaysia have encouraged manufacturers and consumers to shift to R-32. The Indian government has explicitly supported R-32 through its energy labelling program, and major AC brands like Voltas and Blue Star now offer R-32 models as standard.
Europe’s Embrace of R-32
In alignment with the EU’s F-Gas Regulation, European countries began transitioning away from R-410A as early as 2015. R-32 quickly became the go-to replacement due to its better GWP rating and availability.
Brands like Panasonic, Mitsubishi Electric, and LG now ship nearly all of their residential units into the EU with R-32 pre-installed. As of 2023, more than 80% of new AC installations in Europe use R-32, according to EPEE.
Australia and New Zealand Follow Suit
Australia’s HVAC market has also pivoted toward R-32, supported by the Australian Refrigeration Council’s safety training initiatives. Local standards have adapted to allow larger refrigerant charges and improved technician guidelines for A2L systems.
North America’s Turning Point
Historically slower to adopt, the U.S. and Canada have begun embracing R-32 more widely due to:
-
State-level HFC phasedown laws (e.g., California’s AIM Act compliance)
-
EPA SNAP approvals for R-32 use in residential and light commercial AC
-
Widespread acceptance by OEMs like Carrier, LG, and Midea
While R-454B is also present in the North American market, R-32 is gaining favor due to its:
-
Superior efficiency
-
Global servicing infrastructure
-
Simpler chemical composition and better serviceability

Benefits of Global Harmonization
1. Streamlined Manufacturing
OEMs can build fewer product variants, reducing complexity and cost.
2. Unified Training and Certification
Technicians globally can be trained on one primary refrigerant, reducing the burden on training institutions and improving safety.
3. Regulatory Alignment
Global adoption of R-32 supports cross-border trade and makes compliance with international climate targets more achievable.
Final Thoughts
The numbers are in: with over 160 million units already in operation worldwide, R-32 is not just a viable alternative—it’s a proven leader in the refrigerant transition. For manufacturers, contractors, and regulators alike, following the global momentum behind R-32 ensures access to a stable, serviceable, and climate-conscious HVAC solution.
