Carbon credits and the Sustainable Development Goals.

A carbon credit does more than cancel a tonne of CO₂. The best projects also deliver clean water, health, jobs and biodiversity — measurable progress against the United Nations’ 17 Sustainable Development Goals. This is the complete reference: how credits map to the SDGs, the project types and mechanisms behind them, and the standards and registries that keep them honest.

THE FOUNDATION

What is sustainable development?

Sustainable development means meeting today’s needs without compromising the ability of future generations to meet theirs — balancing climate, nature, and human well-being. In 2015 every UN member state adopted 17 Sustainable Development Goals (SDGs) as a shared 2030 blueprint. Carbon credits are one of the few mechanisms that channel private finance directly toward several of these goals at once: they put a price on a tonne of avoided or removed CO₂, and the projects that earn them often improve health, water, energy access and livelihoods in the same place.

MECHANISM

Avoidance vs removal.

The two fundamental ways a credit reduces atmospheric carbon. Both matter; for net-zero claims the mix matters most.

Avoidance (reduction)

Prevents emissions that would otherwise have happened — protecting a standing forest, capturing landfill gas, or switching a household from wood to a clean stove. The tonne never enters the atmosphere.

REDD+ · clean cooking · renewable energy · landfill gas · refrigerant destruction
Removal (sequestration)

Physically takes CO₂ that is already in the atmosphere and stores it in trees, soil, rock or geological storage. Durable removals are what credible corporate net-zero claims require for residual emissions.

reforestation · blue carbon · biochar · soil carbon · direct air capture

CO-BENEFITS & CHARACTERISTICS

The signals buyers screen for.

Beyond carbon, projects carry characteristics that signal extra environmental and social value — and higher integrity.

Biodiversity

The project measurably protects or restores species and habitats alongside carbon.

Blue carbon

Carbon stored in coastal and marine ecosystems such as mangroves and seagrass.

Restoration

Actively rebuilding a degraded ecosystem (vs simply preserving an intact one).

Preservation

Protecting an intact, at-risk ecosystem from conversion or degradation.

Sustainable water

The project safeguards water quality, supply or catchment health.

Plastic

Linked to verified plastic collection or recycling outcomes.

CCB Standards

Climate, Community & Biodiversity Standards — a label for strong social and ecological co-benefits.

CORSIA-eligible

Approved for the aviation industry’s international offsetting scheme — a high-integrity bar.

STANDARDS & REGISTRIES

Who certifies and tracks a credit.

A standard is the rulebook a project is certified against. A registry is the public database that issues serialized credits, tracks ownership, and records retirements so each tonne is only ever counted once. These are the bodies operating across the global carbon market — see how we vet and which we accept →

SUSTAINABILITY & SDGs — FREQUENTLY ASKED

Common questions.

What are the UN Sustainable Development Goals (SDGs)?

The Sustainable Development Goals are 17 global goals adopted by all UN member states in 2015 as part of the 2030 Agenda — a shared blueprint to end poverty, protect the planet and ensure prosperity for all. They range from No Poverty (SDG 1) and Clean Water (SDG 6) to Climate Action (SDG 13) and Life on Land (SDG 15).

How do carbon credits support the SDGs?

Every high-quality carbon credit advances SDG 13 (Climate Action) by avoiding or removing a tonne of CO₂e. Beyond that, projects deliver "co-benefits" mapped to other SDGs: clean cookstoves improve health (SDG 3) and gender equality (SDG 5); renewable energy delivers affordable clean energy (SDG 7); forestry protects life on land (SDG 15); and blue-carbon projects protect life below water (SDG 14).

What is the difference between carbon avoidance and carbon removal?

Avoidance (or reduction) prevents emissions that would otherwise occur — for example protecting a forest or capturing landfill gas. Removal physically takes CO₂ already in the atmosphere and stores it — for example reforestation, biochar or direct air capture. Credible corporate net-zero claims require durable removals for residual emissions.

What is the difference between a carbon standard and a registry?

A standard (such as Verra’s VCS or Gold Standard) is the rulebook and methodology a project is certified against. A registry is the database that issues serialized credits, tracks ownership, and records retirements so a credit can only be used once. Some organisations operate both.

What are co-benefits in a carbon project?

Co-benefits are the social and environmental outcomes a project delivers in addition to reducing carbon — biodiversity protection, clean water, local jobs, gender equality and health improvements. They are how a single carbon project contributes to multiple SDGs, and are often verified under labels like the CCB Standards.

Are carbon credits aligned with ESG and corporate net-zero goals?

Yes. Many businesses use SDG-aligned carbon credits as part of their ESG and net-zero strategies. For science-based net-zero, avoidance credits address the journey while durable removals address residual emissions; CORSIA-eligible and CCB-labelled credits carry higher-integrity signals for ESG reporting.

How do I choose a carbon project that matches the SDGs I care about?

Each methodology in our shop is tagged with the SDGs and co-benefits it supports, so you can pick by impact — for example clean cooking for health and gender equality, reforestation for life on land, or blue carbon for ocean ecosystems. Browse the offset shop and filter by what matters to you.

Turn the goals into action.

Calculate your footprint, then offset it with a project matched to the Sustainable Development Goals you care about — retired on a public registry, certified in your name.
