Nesting Projects within Jurisdictional REDD+

Updated 2026-11-02 · 4 min read · By the akar.earth specialist team

REDD nesting explained: how projects fit inside provincial and national REDD+ programmes, how baselines are allocated, and what nesting means in Indonesia.

Nesting means fitting a REDD+ project inside a jurisdictional programme, such as a province or country, so that the project’s baseline and credits are carved out of the jurisdiction’s total and the same avoided emissions are not counted twice. It is now the direction of travel for REDD+, through Verra’s VM0048 baseline allocation, the Jurisdictional and Nested REDD+ (JNR) framework, and host-country rules like Indonesia’s.

Why nesting emerged

Projects and governments both claim forest emission reductions. A province may receive results-based payments for lower deforestation while a project inside it sells credits for the same hectares. Without coordination, that is double counting. Project baselines set independently can also add up to more avoided deforestation than the jurisdiction actually achieved. See the REDD+ baseline debate.

How nesting works

Different frameworks handle details differently:

• Verra VM0048 uses jurisdictional-scale activity data and risk maps to allocate baselines to projects. See VM0048 jurisdictional allocation.
• Verra JNR allows jurisdictional programmes and nested projects under one framework. See JNR framework.
• ART TREES credits jurisdictions directly with serialised 1 tCO2e credits; projects sit within government benefit-sharing rather than earning ART credits themselves. See ART TREES.

Nesting in Indonesia

Indonesia has taken a sovereign approach to forest carbon. Its national FOLU Net Sink 2030 target, its NDC and its domestic carbon trading framework (Perpres 110/2025, building on Perpres 98/2021) frame how projects relate to national accounting. Forestry carbon trading procedures are set out in ministerial regulations, with Permenhut 6/2026 the latest, naming social forestry, customary forests and communities as legitimate participants.

Indonesia also has jurisdictional programmes, including provincial programmes with World Bank funds. FCPF and ISFL credits can move into the ART registry from the World Bank’s CATS registry, which links Indonesian provincial programmes with international crediting routes.

Practical points for projects:

1. Register domestically. Exchange-traded units must be in SRUK, which replaces SRN-PPI.
2. Check authorisation if credits will be transferred abroad or used for compliance, and whether a corresponding adjustment is needed.
3. Align baselines with national and provincial reference levels.
4. Clarify benefit-sharing with the government and communities.
5. Plan for reconciliation if the jurisdiction’s performance affects project credits.

See FOLU Net Sink 2030 and Indonesia’s NDC.

Step-by-step nesting readiness

1. Map your project against provincial and national programme boundaries.
2. Identify which reference level applies and how allocation works.
3. Compare your current baseline with the likely allocated baseline.
4. Review legal requirements for registration, authorisation and benefit-sharing.
5. Align monitoring data formats and forest definitions with national systems.
6. Model the financial effect of allocation and possible haircuts.
7. Engage early with provincial and national authorities.

Benefits of nesting for projects

Nesting is not only a constraint. A nested project gains legal clarity, a baseline that buyers trust more, and a clearer route to authorisation for Article 6 or compliance uses. It can also access jurisdictional data and monitoring systems. The trade-off is less control over baseline volume and dependence on government performance. For many Indonesian projects, the credibility gain outweighs the volume risk, especially as buyers screen for double-counting risk.

Data alignment in practice

Use the same forest definition, land-cover classes and minimum mapping unit as the national system where possible, or document a clear crosswalk. Keep forest change maps reproducible so they can be compared with provincial and national monitoring. Discrepancies discovered late are expensive to resolve.

Common mistakes

• Assuming an international registry listing is enough without national registration.
• Treating jurisdictional reference levels as irrelevant to a voluntary project.
• Using different forest definitions or maps from the national system.
• Not budgeting for reduced volumes after allocation.

What good evidence looks like

For a VVB and buyer: evidence of national registration and any authorisation; documentation of how the baseline aligns with or is allocated from the jurisdictional reference level; monitoring data consistent with jurisdictional maps; and benefit-sharing agreements. Buyers will also check that no other entity claims the same reductions.
