Experts and the international community agree on the need to transitioning from a linear “take-make-dispose” economy to a circular economy as a way to address environmental planetary crisis. A circular economy – where materials and products are reused and regenerated – can also foster socio-economic development. The transition to a circular economy may create new trade opportunities and risks, including for trading partners.  The shift towards a circular economy raises important questions, such as: How to design circular regulations (e.g., definitions, objectives, types of measures)?  How can domestic circular economy initiatives be coordinated at a bilateral or multilateral level to avoid trade disruptions? How can trade policies and regulations enable an inclusive transition that leaves no one behind?
