REDD+

Examples of issues addressed by REDD+ in tropical forest landscapes: large-scale deforestation visible from space (top), conversion of carbon-rich peat forests for agriculture such as oil-palm (left), and community-based efforts to reduce forest degradation by creating income incentives for conservation (right).

REDD+ is a voluntary climate change mitigation framework developed under the United Nations Framework Convention on Climate Change (UNFCCC). It aims to encourage developing countries to reduce greenhouse gas emissions from deforestation and forest degradation, and to promote conservation, sustainable forest management, and enhancement of forest carbon stocks through financial incentives and policy support. The acronym is commonly expanded as "reducing emissions from deforestation and forest degradation in developing countries", and the "+" denotes the additional forest conservation and enhancement activities included in the UNFCCC scope.

UNFCCC decisions describe REDD+ as a phased approach, beginning with "readiness" activities (planning, capacity-building and institutional development), moving to implementation of national policies and measures, and evolving toward results-based actions that are fully measured, reported and verified. Countries undertaking REDD+ are expected to develop a national strategy or action plan, establish a forest reference (emission) level (FREL/FRL) as a benchmark for assessing performance, and build a national forest monitoring system to support monitoring, reporting and verification (MRV). UNFCCC decisions also include social and environmental safeguards (often referred to as the CancĂșn safeguards) and require countries seeking results-based payments to provide information on how safeguards are addressed and respected.

REDD+ is supported through a mix of multilateral and bilateral channels and can receive results-based finance when reported results meet UNFCCC methodological and transparency requirements under the Warsaw Framework on REDD-plus. A 2024 multi-country impact evaluation reported modest average forest outcomes and limited average welfare effects, with impacts not always sustained over time. Reviews and methodological assessments highlight uncertainties in baselines (reference levels), additionality, leakage, non-permanence and measurement capacity, especially for forest degradation and carbon pools that are harder to quantify. Criticisms and controversies also focus on governance and equity issues, including land tenure and carbon rights, benefit sharing, and the participation and consent of Indigenous peoples and local communities, alongside broader debates over the role of forest offsets in climate policy.

REDD+ remains an active part of the UNFCCC and Paris Agreement architecture. Most of the core UNFCCC decisions that define REDD+ were adopted between 2010 and 2015, including the Warsaw Framework on REDD-plus (2013). Countries continue to report REDD+ results through technical annexes to developing-country reports, including under the Paris Agreement's enhanced transparency framework via technical annexes to biennial transparency reports (BTRs). Results-based finance also continues through multilateral channels such as the Green Climate Fund's REDD+ results-based payments window.
