This could range from harmonising sustainability standards, or at least of methodologies, to the liberalisation of green goods and services. The latter, however, is easier said than done, it has languished with the rest of the Doha results in the WTO context, and is proving difficult to effect at the plurilateral level among like-minded countries. Asia-Pacific Economic Cooperation (APEC) members managed to conclude an agreement of this sort, cutting tariffs on a slim list of 54 goods to 5 per cent as of 2015. The real prize in this respect is non-tariff barriers, as well as services. It is hoped that the current plurilateral efforts to negotiate an Environmental Goods Agreement will eventually lead to such broader commitments.
