This synthesis report summarizes lessons from the UNEP Green Economy and Trade Opportunities Project, which identified, assessed and harnessed trade opportunities arising from the transition to a green economy. The authors combine international research with case studies from around the world - describing sustainability standards for farming in Chile, organic agriculture in South Africa, biotrade in Peru, solar energy in Ghana and fisheries in Viet Nam. The case studies reveal how trade can drive sustainable development, promote social inclusion and reduce poverty. They also highlight a range of opportunities, from sustainable agriculture and value chains for native biodiversity, to enhanced solar energy production for export and improved international certification in aquaculture.
