UN-REDD+ assists countries to seize innovative opportunities to reduce greenhouse gas emissions from deforestation and forest degradation.

Reducing emissions from deforestation and forest degradation

Forests are a readily available, effective, and cost-efficient key nature-based solution that can provide up to a third of the mitigation required to keep global warming well below 2°C. Forests have a mitigation potential of over 5 GtCO₂e per year through halting forest loss and degradation and through sustainable forest management, conservation, and restoration (REDD+).

REDD+ is a climate change mitigation solution developed by Parties to the United Nations Framework Convention on Climate Change (UNFCCC).

Its framework, the Warsaw Framework, was adopted in 2013 at COP 19 in Warsaw and provides methodological and financing guidance for implementing REDD+ activities.

The Paris Climate Agreement recognises REDD+ and the central role of forests in Article 5.

REDD+ reduces deforestation through the conservation and sustainable management of forests and supports developing countries in turning their political commitments, as represented in their Nationally Determined Contributions, into action on the ground.

Forests mitigate climate change because of their capacity to remove carbon from the atmosphere and to store it in biomass and soils. When forests are cleared or degraded, they can become a source of greenhouse gas (GHG) emissions by releasing the stored carbon. It is estimated that deforestation and forest degradation account for approximately 11 per cent of global CO₂ emissions.

To date, 118 countries have included forest and land use in their Nationally Determined Contributions pledges. This represents 162 million hectares of restored, reforested and afforested land, which is in line with the Bonn Challenge and the New York Declaration on forests.

Since 2008, the UN-REDD Programme (led by United Nations Environment Programme (UNEP), Food and Agricultural Organization, and United Nations Development Programme) has supported 65 partner countries in their nationally led efforts to become “REDD+ ready” and qualify for results-based payments.

As of today, UN-REDD countries have submitted forest emissions reductions equal to taking 150 million cars off the road for a year. And UN-REDD has channelled and mobilised more than USD 1 billion since its inception.

Within the UN-REDD Programme, UNEP leads on private-sector engagement, safeguards, knowledge management, and communications.
