GWP, ODP and CO2 Equivalent of Refrigerants

Choose the type that best describes the equipment. The type decides which service bans and prohibitions apply:

• Refrigeration system (stationary) – refrigeration and freezer systems built on site, e.g. supermarket refrigeration, cold rooms and industrial refrigeration.
• Self-contained refrigeration (plug-in) – factory-built refrigerated and freezer cabinets with a built-in unit that plug into a socket, e.g. ice cream and drinks coolers.
• Chiller – units that cool a liquid (water or brine) for comfort or process cooling.
• Air conditioning / heat pump – stationary air conditioners and heat pumps, e.g. split, VRF and air-to-water heat pumps.
• Transport refrigeration (truck, trailer, container) – refrigeration units on trucks, trailers, light vehicles, reefer containers and railway wagons. Covered by the leak checks in the EU.
• Vehicle air conditioning (car, bus) – air conditioning in cars, vans and buses. Not covered by the leak checks of the F-gas Regulation but by its own rules (in the EU the MAC Directive 2006/40/EC).

What the circuit is used for. It decides which refrigerants are suggested as replacements and starred (*) in the comparison:

• Freezer – freezers and freezer rooms for frozen goods (about −18 °C and colder).
• Chiller cabinet / cold room – refrigerated cabinets, cold rooms and process cooling for chilled goods (about 0 to +10 °C).
• AC / heat pump / liquid chilling – air conditioning, heat pumps and liquid chillers.
• Industrial process refrigeration – refrigeration in industrial processes (e.g. chemicals, food production). In the USA the leak rate trigger is 30 % per year.
• Other – other use; all common replacements are shown.

The EU annex IV distinguishes split systems (indoor and outdoor unit with refrigerant lines) from monoblocks (the whole refrigerant circuit in one casing). Air-to-air splits heat or cool air, air-to-water splits heat water.

Choose the country where the system is installed and used. The rule set decides which GWP values are legally binding and which requirements are worked out:

• EU – Regulation (EU) 2024/573 – Applies in the EU member states.
• United Kingdom (GB) – F-gas Regulation 517/2014 (retained) – Applies in England, Scotland and Wales: (EU) 517/2014 as retained. Leak checks as in the EU; service ban for GWP ≥ 2500 from 40 t CO₂e since 2020. DEFRA is not changing the rules in 2026; the quota goes from 31 % to 24 % on 1 January 2027 (status October 2026). Northern Ireland follows (EU) 2024/573: choose EU.
• Norway (EEA) – Regulation (EU) 517/2014, Product Regulations – Norway applies (EU) 517/2014 through the EEA Agreement. (EU) 2024/573 is not yet part of the EEA Agreement: check the current status.
• Switzerland – ChemRRV (SR 814.81) annex 2.10 – Own rules, stricter than the EU. The amended annex 2.10 (AS 2025 747) applies from 1 January 2027: bans on new plants by use, capacity and GWP, refilling restrictions and leak checks.
• Türkiye – Florlu Sera Gazları Yönetmeliği (2024) – Published in Resmî Gazete on 15 October 2024 (no. 32693). Leak checks as in the EU (madde 12). The regulation restricts servicing with refrigerants of GWP ≥ 2500; check dates and thresholds in the legal text.
• USA – EPA, Clean Air Act §608 and AIM Act – Limits in pounds (lb). Leaks must be repaired when the annual leak rate exceeds 10 % (comfort cooling), 20 % (commercial refrigeration) or 30 % (industrial process refrigeration). No fixed check intervals as in the EU.
• Canada – SOR/2016-137 (Halocarbon Alternatives Regulations) – HFC phase-down by 85 % by 2036 and GWP limits for new equipment (Schedule 1.1). Leak checks and certification are provincial. Safety standard CSA B52. GWP per AR4.
• Australia – Ozone Protection and Synthetic Greenhouse Gas Management Act 1989 – HFC imports under quotas, down to 15 % of the baseline in 2036. Import ban on small AC (≤ 2.6 kg, GWP > 750). ARC licence to handle and trade refrigerants. Safety standard AS/NZS 5149. GWP per AR4.
• New Zealand – Ozone Layer Protection Act 1996 – Bulk HFC imports need an EPA permit since 1 January 2020 under the Kigali schedule. Safety standard AS/NZS 5149. GWP per AR4.
• Japan – Fluorocarbons Act (フロン排出抑制法) – Simple inspection every 3 months for all commercial units; periodic inspection by compressor rated output. HFOs and natural refrigerants are not covered.
• China – ODS Regulation 2024 (HFC quotas) – The revised ODS Regulation (since 1 March 2024) brings HFCs into the quota system. Kigali Article 5 group 1. GWP per AR4.
• Hong Kong – Ozone Layer Protection Ordinance (Cap. 403) – Import and export controls for 18 HFCs since 1 December 2025: import quota and a licence for each consignment; consumption to fall by 85 % from the baseline by 2036 (the Kigali schedule for non-Article 5 parties, not China's). GWP per AR4. Authority: EPD.
• South Korea – Ozone Layer Protection Act and Clean Air Conservation Act – HFC phase-down since 2023 (Kigali Article 5 group 1). Refrigerant management under the Clean Air Conservation Act from 20 RT (≈ 70 kW). GWP per AR4.
• Singapore – EPMA Part 10A (NEA) – GWP limits for new equipment since 1 October 2022: household air conditioners 750, household refrigerators and water-cooled chillers 15. From 1 July 2027 centralised commercial refrigeration 150, from 1 July 2028 car air conditioning 150 (GHG Regulations 2022). GWP per AR5.
• India – Kigali Article 5 group 2 – HFC freeze on 1 January 2028 (baseline 2024–2026), then step by step to −85 % in 2047. GWP per AR4.
• Other countries – Kigali Article 5 group 1 (Latin America, Africa, South-East Asia etc.) – The app calculates GWP, ODP and CO₂e and shows the Kigali phase-down for group 1 and national HFC rules for some countries. Always check the country's own rules.
• Other countries – Kigali Article 5 group 2 (Gulf states, Iran, Iraq, Pakistan) – Bahrain, Iran, Iraq, Kuwait, Oman, Pakistan, Qatar, Saudi Arabia and the United Arab Emirates (and India): freeze in 2028. No national requirements in the app.
• Other countries – Kigali, non-Article 5 (developed countries not in the list) – Developed countries without their own choice in the list: phase-down since 2019 to −85 % in 2036. No national requirements in the app.

Choose which GWP values are shown in the tables and the chart. The legal requirements always use the rule set's values, whatever you choose here.

• The rule set's values (legally binding) – Choose this for anything legal: leak checks, labelling of units, logbooks and reports to the authorities. These are the values the authority of the chosen country uses (in the EU: AR4 for HFCs and AR6 for HFOs).
• IPCC AR4 (2007) – IPCC Fourth Assessment Report (2007). The values of the EU's older F-gas Regulation and on most labels and data sheets; also used in the UK, the USA, Japan and the Kigali Amendment. Choose it to compare with older documents or US and Japanese data.
• IPCC AR5 (2013) – IPCC Fifth Assessment Report (2013). Used in national climate reporting under the Paris Agreement and in some environmental product declarations (EPD) and carbon accounts. Not legally binding for refrigerants in the EU.
• IPCC AR6 (2021) – IPCC's latest report (2021): today's best estimate of the climate impact. Choose it for carbon accounts and sustainability reports that ask for the latest values. Not legally binding for refrigerants in the EU; HFCs mostly get higher values than with AR4.
