HFC Tax: Effective January 1, 2025

Context of the HFC Tax
The tax on hydrofluorocarbons (HFC), established in France by the General Tax Code (Code général des impôts) in Chapter VI, Article 302 bis F, aims to reduce greenhouse gas emissions with high global warming potential (GWP or PRG).
HFCs, used primarily in refrigeration, air conditioning, and heat pump systems, constitute an alternative to chlorofluorocarbons (CFCs) that degraded the ozone layer. However, their significant climate impact makes them a major environmental issue, requiring measures to limit their use.
Objectives of the HFC Tax
1. Reduction of climate emissions
Encourage the transition toward low environmental impact refrigerants.
2. Promotion of sustainable alternatives
Support the adoption of:
- Natural refrigerants (CO₂, ammonia, hydrocarbons)
- Synthetic refrigerants with low GWP
3. Compliance with climate commitments
Contribute to the objectives of:
- The Paris Agreement
- The requirements of the European F-GAS regulation
How the HFC Tax Works
The tax is calculated based on the global warming potential (GWP) of refrigerants and expressed in tonnes of CO₂ equivalent (tCO₂e).
Progressive schedule
The rate evolves progressively according to the following schedule:
| Year | Rate per tCO₂e |
|---|---|
| 2024 | 10 € |
| 2025 | 15 € |
| 2026 | 20 € |
| 2027 | 25 € |
| 2028 and beyond | 30 € |
Calculation Examples
Example tax for a refrigerant in 2025
Rate: 15 €/tCO₂e
| Refrigerant | GWP | Quantity | Calculation | Tax |
|---|---|---|---|---|
| R134a | 1430 | 10 kg | 10 kg × 1430 × 15 € / 1000 | 214.50 € |
| R410A | 2088 | 1 kg | 1 kg × 2088 × 15 € / 1000 | 31.32 € |
| R404A | 3922 | 5 kg | 5 kg × 3922 × 15 € / 1000 | 294.15 € |
Non-Taxed Alternatives
The following refrigerants are not subject to this tax, as they are not HFCs:
HFO Refrigerants
- R1234yf: GWP = 4
- R1234ze: GWP = 1
Natural Refrigerants
- R717 (NH₃): Ammonia
- R744 (CO₂): Carbon dioxide
- R290: Propane
These alternatives allow you to avoid the tax burden while reducing environmental impact.
Available Alternatives
To reduce environmental impact, several alternatives to HFCs are available:
1. Natural Refrigerants
CO₂ (R744)
- Application: Commercial refrigeration, heat pumps
- Advantages: GWP = 1, non-toxic, non-flammable
- Disadvantages: High operating pressure
Ammonia (R717)
- Application: Industrial refrigeration
- Advantages: GWP = 0, excellent thermodynamic properties
- Disadvantages: Toxicity, requires specific equipment
Hydrocarbons (R290, R600a)
- Application: Commercial, domestic refrigeration
- Advantages: Negligible GWP, high energy efficiency
- Disadvantages: Flammability, usage restrictions
2. HFO Refrigerants
R1234yf
- Application: Automotive air conditioning
- Advantages: GWP = 4, compatibility with existing systems
- Disadvantages: Higher cost
R1234ze
- Application: Commercial refrigeration, heat pumps
- Advantages: GWP = 1, low environmental impact
- Disadvantages: Reduced cooling capacity
3. Transition Blends
Hybrid refrigerants combining HFC and HFO to facilitate the transition while reducing climate impact.
Clarifications on HFOs
Although HFO refrigerants are interesting alternatives due to their low GWP, their atmospheric degradation can produce trifluoroacetic acids (TFA), whose environmental effects require further study.
