Scientific research by RIVM’s Guus Velders stood partly at the basis of the HFC global climate agreement.

Construction and demolition waste are being recycled on a large scale to use as a foundation for e.g. roads, but recycled building materials are hardly ever used in the construction of buildings.

Without global agreement on the use of HFCs, their contribution to the greenhouse effect may increase sharply to 10 percent of that of CO2 by 2050. The current contribution is less than 1 percent.

Hydrofluorocarbons (HFCs) are potent greenhouse gases used in refrigerators and air conditioners and are released primarily at the end of the life-span of these products.
