Forest carbon guides for Indonesia: practical how-tos on ARR, REDD+, blue carbon, dMRV, agroforestry, Article 6, biodiversity and project finance.
Our guides are practical, step-by-step explanations of how to plan, measure, finance and verify nature-based carbon projects in Indonesia and Southeast Asia. Each one answers a specific question a developer, buyer, exporter or government team actually faces, and links to the standards and rules behind it.
There are around 60 guides. This page helps you find the right one.
How the guides are written
Every guide starts with a direct answer, then explains the method, the Indonesian context, common mistakes and where to go next. We name the methodology, regulation or tool rather than speaking in generalities. Where a number or rule may have changed, we tell you where to check the current version.
Start here
If you are new to forest carbon, read these three in order:
- How forest carbon credits work: the core concepts.
- The carbon project lifecycle from idea to issuance: the steps and who does what.
- Removals vs avoidance credits: why buyers treat them differently.
Guides by task
Planning a tree-planting project. ARR project feasibility: a 10-point checklist, land eligibility, species selection, costs and ex-ante carbon estimation. Smallholder developers should read aggregating smallholders into one ARR project.
Protecting forest. Drivers of deforestation in Indonesia, the REDD+ baseline debate, peatland REDD+, improved forest management and nesting projects in jurisdictions.
Coastal projects. Mangrove restoration step by step, measuring mangrove soil carbon, aquaculture pond rehabilitation, seagrass and blue carbon policy.
Measuring and monitoring. Plot sampling design, mobile tree measurement, RTK GNSS, allometric equations, Sentinel-2, GEDI, drones, deforestation alerts, uncertainty deductions and building a dMRV data pipeline. Ground truth vs satellite explains why field plots still matter.
Smallholder landscapes and EUDR. Coffee, cocoa and rubber agroforestry, soil carbon on smallholder farms, farmer registration, FPIC and consent records and one field dataset for carbon and EUDR.
Markets, policy and finance. Compliance vs voluntary markets, Article 6.2 ITMOs, the Article 6.4 mechanism and authorisation letters. For buyers, avoiding greenwashing with nature claims.
Nature and biodiversity. Biodiversity credit methods, acoustic and eDNA monitoring, ecosystem service valuation, HCV and HCSA assessments, and TNFD for land-intensive companies.
Guides by reader
- Project developers should focus on feasibility, measurement and the project lifecycle.
- Corporate buyers should start with removals vs avoidance, avoiding greenwashing and compliance vs voluntary markets.
- Exporters should read one field dataset for carbon and EUDR, then the commodity pages in the EUDR hub.
- Government and NGO teams should pair the social forestry and community engagement guides with the regulation hub.
- Field teams should read the plot design, mobile measurement and RTK guides before their first campaign.
Guides and the rest of the site
Guides explain how to do something. Other sections cover the reference material:
- Standards for methodology and program rules.
- Indonesian regulation for laws and registries.
- EUDR for commodity-specific compliance pages.
- Comparisons for side-by-side choices.
- The glossary for definitions.
If you want to check your numbers as you read, our free tools include an ARR estimator, a tree CO2 calculator, an eligibility quiz and an EUDR readiness check. If your team needs structured learning, see our training service. All guides are listed below.
Frequently asked questions
Where should a beginner start?
Read How Forest Carbon Credits Work first, then The Carbon Project Lifecycle from Idea to Issuance. Together they explain the concepts and the steps every project goes through.
Are these guides specific to Indonesia?
Yes, where it matters. Each guide explains the general method and then the Indonesian or Southeast Asian context: land tenure, regulation, commodities, climate and field conditions.
Do the guides replace a feasibility study?
No. They help you ask the right questions and spot problems early. A real project still needs site data, tenure checks and a model built for your land.
