Although circular trade is a key enabler of a global circular economy, a range of regulatory and technical challenges are inhibiting its advancement. These include a lack of mutually recognized definitions, classifications, interoperable standards, regulations and conformity procedures concerning circular economic activities or goods. Furthermore, as an emerging area of activity, the circular economy has itself only been embedded to a limited degree in bilateral, regional and plurilateral trade and economic cooperation agreements. This restricts the scope and potential for collaboration around transboundary issues such as illegal waste, supply-chain transparency and traceability, investment or the issues pertaining to mutual recognition, technical barriers to trade, and trade facilitation.
