This report has been prepared by the Trade, Policy and Planning Unit of the United Nations Environment Programme. It is a key component of the Green Economy and Trade Opportunities Project. It aims to identify a range of international trade opportunities in various key economic sectors associated with the transition to a green economy, identify policies and measures that may act as facilitators and overcome hindrances to seizing trade opportunities arising from the transition to a green economy, and assist governments, the private sector and other stakeholders to build capacity to take advantage of sustainable trade opportunities at the national, regional or international level.
