The document discusses the circular economy concept and policies supporting the transition to a circular economy in Europe. It defines a circular economy as an economic system of closed loops that aims to keep resources in use for as long as possible. The European Commission has adopted an ambitious action plan to stimulate Europe's transition, with goals like recycling 65% of household waste by 2030. Important EU policies include the Circular Economy Package and strategies on plastics and zero waste. However, further international policies are still needed to develop standards, share knowledge, and build coalitions to accelerate the global transition to circularity.
