The Green Customs Initiative (GCI) enhances the capacity of customs and border control officers to enforce and foster compliance to trade-related conventions, MEAs, and corresponding national legislation. GCI focuses on commodities such as ozone-depleting substances, toxic chemicals, hazardous wastes, endangered species, and living-modified organisms. The initiative is a forum for coordinated and cost-effective development of tools, delivery of training, and awareness-raising of customs officers and border control officers, through leveraging its partners’ resources and expertise. It complements and enhances existing customs training efforts under the respective agreements. For some of the MEAs involved, GCI is the structured means of interaction with the customs community.
