This scoping review, commissioned by the Global SDG Synthesis Coalition, systematically assesses available evidence from systematic reviews and United Nations evaluation reports related to the Planet Pillar of the Sustainable Development Goals (SDGs). It identifies the strength and distribution of evidence across intervention types and SDG target areas, including WASH, sustainable forest management, climate change resilience, and more. The review aims to inform the development of future living syntheses for catalytic action where progress is lacking.
