Teravent
Nature-Based
Carbon Standard

Governing standard for nature-based carbon removal and avoidance projects - from afforestation and blue carbon to peatland restoration and improved forest management - registered under the Teravent Carbon Registry.

TNS-001-v1.0 Document Reference
8 Nature Pathways
8 Governing Modules
TCR Teravent Carbon Registry

TNS v1.0 governs nature-based carbon projects that sequester or avoid emissions through biological systems - forests, soils, wetlands, coastal ecosystems, and grasslands - at all scales from smallholder farms to jurisdictional landscapes.

This Standard is wholly independent. It does not incorporate by reference, adopt, or depend upon any external carbon crediting programme, registry, standard-setting body, or methodology framework. All requirements are self-contained within this document and its eight methodology Annexes.

TNS v1.0 issues Teravent Nature Credits (TNCs) - verified units representing one tonne of CO₂ equivalent removed from or not released to the atmosphere through a registered nature-based project.

Permanence Classification

Every Teravent Nature Credit (TNC) carries a permanence class encoding the expected durability of its biological carbon storage.

Class I
Biological
10 – 100 years

Soil organic carbon and short-rotation agricultural systems subject to natural decomposition cycles and management reversals.

Buffer: 20 – 40%
Agriculture & Soil Carbon · Agroforestry (short rotation)
Class II
Ecological
100 – 500 years

Forest biomass and long-lived ecosystem carbon stores subject to fire, drought, pest, and land-use-change risk over multi-decadal horizons.

Buffer: 10 – 30%
ARR · Ecosystem Restoration · IFM · Biodiversity Conservation · Blue Carbon · Peatland
All nature-based projects contribute to the Teravent Buffer Pool. Buffer contribution rates are determined by the project's Non-Permanence Risk Rating (NPRR), assessed by an accredited VVB at validation and each verification. Higher-risk projects (fire-prone, drought-vulnerable, or low-tenure-security) contribute more to the pool to protect buyers against reversal.
Standard Architecture

Eight Governing Modules

TNS v1.0 is structured across eight self-contained modules that together constitute a complete, wholly independent crediting framework for nature-based carbon removal and avoidance.

01

Governance & Scope

TSA issuing authority, eight-pathway eligibility table with Annex references, full 25-term definitions glossary including TNC definition, exclusions covering double counting, illegal activities, and FPIC failures.

TSA Authority TNC Definition Exclusions
02

Additionality & Baseline

Three-test additionality framework: regulatory surplus, financial additionality, and common practice. Baseline scenario selection, baseline carbon stock quantification, dynamic baseline update rules, crediting period table for all eight pathways, and permanence risk classification.

Regulatory Surplus Financial Additionality Dynamic Baselines
03

Quantification & MRV

Spatial accounting boundary requirements (5 m GPS accuracy), five-pool carbon assessment table, activity-shifting and market leakage frameworks, uncertainty deduction table (0–50% CI ranges), monitoring plan requirements, and VVB independence and rotation rules.

Five Carbon Pools Leakage Assessment VVB Independence
04

Carbon Durability & Non-Permanence

Two permanence classes (Biological and Ecological), Teravent Buffer Pool mechanics, buffer contribution rates by class and NPRR, reversal event notification within 30 days, force majeure provisions, and progressive buffer release for high-performing projects.

Class I / II Buffer Pool Reversal Protocol
05

Environmental & Social Safeguards

Do No Harm principle, Biodiversity Impact Assessment, native species preference, water and soil requirements, Free Prior and Informed Consent (FPIC), community benefit sharing, gender and equity provisions, labour standards, and independent grievance mechanism.

Biodiversity BIA FPIC Community Benefit
06

Validation & Certification

Eight-stage registration process from Project Concept Note through ongoing verification. Full PDD requirements including BIA, FPIC, and CBS mechanism. Three certification tiers: Standard, Premium, and Frontier. Small project grouping rules for under-200 ha portfolios.

8-Stage Process PDD Requirements Project Grouping
07

Credit Issuance & Labelling

TNC serial number structure with pathway code, country, project ID, and vintage. Net TNC issuance formula. Full credit metadata specification. Five co-benefit quality labels: Biodiversity+, Water+, Livelihoods+, Gender Equity+, and Indigenous Stewardship.

Serial Number Net TNC Formula Co-Benefit Labels

Registry, Retirement & Claims

Teravent Carbon Registry structure and public disclosure requirements, four account types, four permitted claim types including carbon neutral and net zero contribution, double counting prevention, standard review and versioning, and sanctions and independent appeals.
