Phase-Down and Phase-Out of Synthetic Refrigerants
The EU has initiated a comprehensive phase-out of synthetic refrigerants to reduce emissions of climate-damaging CFCs. These regulations bring important changes for companies in the EU:
- Price development: The prices of synthetic refrigerants have risen drastically since 2014. In addition, their production will be reduced by 79% compared to 2015, which will further exacerbate the cost problem.
- Bans on use: Specifically, certain refrigerants may no longer be used from 2030. Examples:
- R404A: This refrigerant has been banned for many applications since 2020.
- R134a: In the EU, its use in new plants will be severely restricted from 2025.
- R407C and R410A: These will also be affected in the EU from 2030.
For more information, see our summary of the F-Gas Regulation EU 2024/573.
Benefits of switching to natural refrigerants
- Cost savings: Natural refrigerants reduce your operating costs in the long term through higher efficiency and less maintenance.
- Environmental benefits: With a low global warming potential, they minimize environmental impact and support sustainable business practices.
- Regulatory compliance: They make it easier to comply with environmental regulations and protect against potential fines.
- Future-proof investments: Investing in natural refrigerants makes your business more resilient to future market and environmental changes.
