Carbon offsets are increasingly seen as a tool to support sustainable development goals and mitigate climate change, according to a MacArthur-supported report by MacArthur Award for Creative and Effective Institution recipient Forest Trends’ Ecosystem Marketplace. The report was based on responses to a 2015 survey of forest carbon project developers from around the world. Collectively, carbon offsets helped clarify land tenure for communities across 2.2 million hectares of land; preserved biodiversity by protecting the habitats of 141 vulnerable or abandoned species; and created nearly 8,000 jobs with training for more than 46,000 people in skills such as agroforestry and carbon accounting and monitoring. An online webinar reviews the report's findings.
