ARR &
Nature-Based Solutions

Afforestation, reforestation, and revegetation programmes represent the most established segment of the voluntary carbon market. Teravent applies strict additionality and baseline requirements - ensuring that only genuinely additional forest carbon removal is credited, in the regions where it matters most.

Overview

How this pathway works

ARR (Afforestation, Reforestation, Revegetation) and REDD+ projects protect and restore forests, grasslands, and degraded lands. These ecosystems absorb CO₂ from the atmosphere into woody biomass, roots, litter, and soils.

Teravent's ARR methodology framework requires continuous satellite monitoring (Teravent MRP-01) and periodic permanent sample plot audits (Teravent MRP-02) for all registered projects. We require IPCC Tier 3 biomass estimation approaches wherever sufficient allometric data exist.

Africa and Latin America hold the greatest opportunity for high-integrity ARR and REDD+ projects - combining large areas of degraded or threatened forest with significant co-benefits for rural communities. Teravent's governance structures are designed to place project communities at the centre of benefit-sharing arrangements.

Supported Sub-Types

Project types accepted

The following variants of the ARR & Forests pathway are currently eligible for registration in the Teravent Registry.

Afforestation on previously unforested or long-degraded land

Reforestation of cleared, burned or degraded forest areas

Community-led revegetation and land restoration programmes

REDD+ reduced deforestation and forest degradation

Improved Forest Management (IFM) - extending rotations, reducing harvest impact

Agroforestry systems integration with existing smallholder farms

Peatland and wetland forest restoration

MRV Confidence

Measurement, reporting
& verification

Teravent's Science Advisory Board assesses each pathway against four MRV dimensions. These scores reflect the current state of measurement science and are updated as methodology evolves.

🔬 Science & Measurement Note

Forest carbon estimation requires allometric equations validated for the specific tree species and regional conditions. Teravent requires Tier 3 biomass estimation (local equations) or Tier 2 (IPCC regional defaults) with conservative discounting applied per MRP-06.

Eligibility Requirements

Key registration criteria

Projects must meet all of the following minimum requirements to be considered for registration under the ARR & Forests pathway. Additional requirements may apply depending on project size, geography, and specific methodology version.

✓

Land has been without forest cover for a minimum of 10 years at project start

✓

Additionality demonstrated using approved baseline methodology

✓

Leakage risk assessed and quantified - displacement buffer applied where necessary

✓

FPIC obtained; community benefit-sharing agreement in place

✓

Buffer pool contribution determined via Teravent risk assessment matrix

Co-Benefits & SDGs

Sustainable Development
Goal alignment

All Teravent-registered ARR & Forests projects must complete an SDG impact assessment at registration and at each verification period. 9 SDGs are tracked for this pathway.
