A circular economy lies at the heart of climate action. Standards and conformity assessment are part of the solution. A circular process covers tangible and intangible requirements, including sustainability of the global value chain based on aspects such as trade, economic factors, corporate responsibility, labour, health and human rights. This brochure outlines how conformity assessment provides assurance on specific aspects such as safety, efficiency, repairability, durability, upgradability, recyclability and reusability – all of which contribute to the robustness of the circle.
