The environmental challenge

Europe extracts far more than it recycles

Every year, the EU extracts 5.2 billion tonnes of natural resources from its own territory (Eurostat, 2024) and generates 2.2 billion tonnes of waste (Eurostat, 2022). Only 41% of this waste is recycled, while 30% still ends up in landfill.

Raw material extraction and waste management have a considerable impact on climate change and biodiversity loss.
