REDD+ stands for reducing emissions from deforestation and forest degradation, with the plus covering conservation, sustainable forest management and enhancement of forest carbon stocks. In plain English, a REDD+ project earns credits by proving that a forest is being protected from a credible threat and that emissions are lower than they would have been without the intervention.

That makes REDD+ very different from reforestation and afforestation credits. ARR projects usually create removals by growing new biomass. REDD+ projects usually create emission reductions by stopping forest carbon from being released in the first place.

The core logic

A REDD+ project has to show four things clearly: what forest area is being protected, what deforestation would likely happen without the project, what actually happened during the monitoring period, and how leakage and reversal risk are handled. The credit volume is the difference between the credible baseline and monitored project emissions, after deductions.

Project, jurisdictional and nested REDD+

One reason REDD+ is complicated is that forest loss is not always best measured one project at a time. Some buyers and standards increasingly prefer jurisdictional or nested approaches, where individual projects are aligned with a larger regional or national accounting framework. That can reduce double counting and inflated baseline risk, but it also means project developers need to understand the host country and jurisdiction rules before assuming a standalone project can be credited.

Verra's VM0048 REDD methodology is designed for project-level REDD activities within a jurisdictional context. ART's TREES standard focuses on jurisdictional and national scale REDD+ accounting.

Why buyers scrutinise REDD+

REDD+ can protect very large areas and finance valuable conservation work, but it is also one of the most scrutinised credit types in the market. Buyers worry about overstated baselines, weak land rights, unclear benefit sharing, leakage and political risk. A good REDD+ project therefore needs more than a carbon model. It needs a defensible theory of change, transparent land tenure, credible monitoring and a story that holds up outside the registry paperwork.

Use this as a first pass to compare REDD+, ARR and other nature-based routes before building a deeper feasibility model.

Once the route looks plausible, move into feasibility modelling so the credit volume, price assumptions and verification costs are tested together.
