Glossary

A field guide to the language.

The terms that recur across the hub, in plain English: how climate outcomes are measured, certified, financed and traded, with the most depth on carbon and nature-based MRV. Cross-linked into the directories.

Core concepts

10

Measurement, Reporting & Verification

MRV

The process of quantifying a project’s climate or nature outcome, documenting it, and having it independently checked. MRV is what turns activity on the ground into a credit a buyer can trust.

Digital MRV

dMRV

MRV built on continuous digital data (satellite, sensors, models, field apps) and software workflows rather than periodic manual reports. Straatos OS runs dMRV end to end, from field capture to registry submission.

Solutions

Operating system (for projects)

The software a developer runs a nature-based project on end to end: the spatial model, field and community monitoring, impact assessment, multi-standard registry submission and public reporting. It hosts data from many external tools rather than locking them in, and produces one verifiable record from the first GPS point to the issued credit.

Solutions

Host, don’t absorb

Straatos’s interoperability stance: reference and ingest data from many external tools rather than rebuilding or locking them in. The hub’s Solutions are the things a project hosts, integrates or connects to.

Solutions

Nature-based solutions

NbS

Actions that protect, restore or sustainably manage ecosystems (forests, mangroves, grasslands) to deliver climate, biodiversity and community benefits.

Nationally Determined Contribution

NDC

A country’s self-set climate pledge under the Paris Agreement, updated every five years. NDCs frame much of the climate finance and policy that reaches the Global South.

Portals

Mitigation & adaptation

The two halves of climate action: mitigation cuts or removes emissions; adaptation builds resilience to impacts already locked in. Much of the Global-South agenda is adaptation, historically the under-funded half.

Climate finance

The flow of capital into climate action, from multilateral funds and development banks to philanthropy and private investment. Its scale and where it lands are tracked closely and contested.

Funders

Just Energy Transition Partnership

JETP

A country-level deal in which wealthy economies pledge finance to help a coal-dependent developing country move to clean energy fairly. South Africa, Indonesia and Vietnam have signed early ones.

Advance market commitment

AMC

A pooled commitment by buyers to purchase a nascent climate good (often durable carbon removal) before it is cheap, to pull supply into existence. Frontier is the best-known carbon-removal AMC.

Buyers

Methods & metrics

9

Carbon Dioxide Removal

CDR

Pulling CO₂ out of the atmosphere and storing it, by nature (reforestation, soils) or engineering (direct air capture, biochar, enhanced weathering). Durable CDR is where much advance-market demand now sits.

Buyers

REDD+

Reducing Emissions from Deforestation and forest Degradation, plus conservation and sustainable management. Credits are earned by keeping carbon in standing forest against a baseline of expected loss.

Conservation projects

Afforestation, Reforestation & Revegetation

ARR

Regrowing forest or vegetation on degraded or non-forest land. Credits come from the carbon newly sequestered as biomass accumulates.

Blue carbon

Carbon captured by coastal and marine ecosystems, above all mangroves, seagrasses and tidal marshes, where much of the carbon is stored in waterlogged soils and is hard to measure.

Above-ground biomass

AGB

The mass of living vegetation above the soil, the main quantity forest-carbon MRV estimates. Measured with LiDAR, radar and optical models, calibrated against field plots.

Additionality

The test of whether a climate benefit would not have happened without the carbon finance. Non-additional credits do not represent real extra impact.

Leakage

When a project simply displaces emissions elsewhere, for example deforestation moving to the next valley. Credible MRV accounts for it.

Permanence & durability

How long the stored carbon stays out of the atmosphere. Forest carbon is reversible (fire, logging); durable removals like biochar are rated for centuries.

Pre-issuance assessment

Rating or screening a carbon project before any credits are issued, so weaknesses in integrity, delivery and price can be caught early. Raters pair the score with improvement actions, specific recommendations a developer can act on to lift quality and value ahead of issuance.

Ratings & data layer

Standards & rules

5

Validation & Verification Body

VVB

An accredited, independent third party that validates a carbon project’s design and verifies its claimed outcomes against a standard. The audit layer that lets a buyer trust a credit.

Providers

Verified Carbon Standard

VCS

The largest crediting standard and registry, run by Verra, dominant in nature-based credits. Defines methodologies and issues credits.

Verra

Jurisdictional REDD+

REDD+ accounted at the scale of a whole state or country rather than a single project, reducing leakage and baseline gaming. ART/TREES is the leading jurisdictional standard.

ART / TREES

Core Carbon Principles

CCP

The ICVCM’s integrity benchmark for high-quality credits. A CCP label signals a programme or methodology meets a common quality bar.

Article 6

The Paris Agreement provision letting countries trade emission reductions internationally. It requires rigorous accounting to avoid double counting, driving registry interoperability.

CAD Trust

Data & sensing

2

Synthetic aperture radar

SAR

A radar imaging technique that sees through cloud and at night, essential for monitoring the persistently cloudy tropics where optical satellites go blind.

Observe layer

Environmental DNA

eDNA

Genetic material shed by organisms into water, soil or air. Sampling it reveals which species are present without seeing or catching them, a fast route to biodiversity ground truth.

Community & equity

3

Free, Prior & Informed Consent

FPIC

The right of Indigenous peoples and local communities to give or withhold consent to projects affecting their land, on their own terms and before activities begin. Straatos records FPIC as evidence.

Benefit-sharing layer

Benefit-sharing (Cui Bono)

How the value of a credit is split with the communities who steward the land. Straatos’s Cui Bono model binds the split and the payment to the verifiable record.

Biodiversity credit

A unit representing a measurable gain or avoided loss in biodiversity, distinct from carbon. Methodologies range from species indicators to a basket of habitat metrics.
