Circular economy policies and initiatives largely take place domestically, and yet they have important interlinkages with international trade. This report explores how to make circular economy policies and trade policies mutually supportive by mapping out potential misalignments and identifying opportunities to align and strengthen both policy areas. The report highlights the various interlinkages between international trade and circular economy, and examines the interactions between trade and circular economy at the policy level, focussing on the multilateral trade regime and regional trade agreements, as well as specific policies to promote the circular economy, such as extended producer responsibility and product stewardship schemes, taxes and subsidies, green public procurement, environmental labelling schemes, and standards.
