OUR INTEGRITY STANDARDS

How we curate every credit.

We’re an aggregator and reseller — not a registry. We source verified credits at wholesale, screen each project against the ICVCM Core Carbon Principles and independent ratings, retire them on the source registry, and give you a certificate you can verify yourself.

SOURCE · SCREEN · RETIRE · CERTIFY
01
Source

We buy verified credits at wholesale from established exchanges and developers — we never originate or issue credits ourselves.

02
Screen

Each project is checked against the ICVCM Core Carbon Principles and independent third-party ratings before it enters our catalogue.

03
Retire

We formally retire credits on the source registry, which generates an immutable public serial number in your name (or ours, for pool retirement).

04
Certify

You receive a branded certificate with a public verification page that links straight to the registry record — verifiable without us.

STANDARDS WE ACCEPT

Registry-issued, independently verified.

Every credit we sell is issued by one of these established standards and carries a public, traceable serial number on its registry.

HOW WE SCREEN FOR QUALITY

The registry label is the start, not the end.

A serial number proves a credit exists; it doesn’t prove it’s high quality. So we layer independent checks on top before a project enters our catalogue.

ICVCM Core Carbon Principles

A cross-registry benchmark for high-integrity credits. We screen every project against it — it’s a floor, not a ceiling.

BeZero Carbon

Independent, like-for-like carbon-credit ratings used to compare quality across projects.

Sylvera

Independent project ratings and satellite-based monitoring, especially for nature and forestry.

WHERE WE SOURCE

Wholesale, from established markets.

We buy in bulk from recognised exchanges, marketplaces, and vetted developers — then retire on your behalf. You never need a registry account or a broker.

Carbonmark

Carbon-credit marketplace

Patch

Programmatic carbon API & marketplace

Xpansiv (CBL)

The largest spot exchange for environmental commodities

Direct developers

Selected, vetted project developers

WHAT WE WON’T LIST

Our screening criteria.

A project is excluded from our catalogue if it meets any of these criteria:

01 Vintage older than 36 months
02 No public registry serial trail
03 Projects flagged by ratings agencies for over-crediting
04 Avoided-deforestation baselines we can’t independently verify
05 Methodologies not assessed under the ICVCM Core Carbon Principles
VERIFY, DON’T TRUST

You don’t have to take our word for it.

We don’t issue credits and we don’t run a registry — so the integrity of what you buy doesn’t rest on our say-so. Every credit is issued by an established standard, screened against the ICVCM Core Carbon Principles and independent ratings, and retired on the source registry.

Each retirement produces an immutable public serial number, and every certificate links to a public verification page showing the registry record. Look it up yourself — that’s the point.

STANDARDS — FREQUENTLY ASKED

Questions about our credits.

Which carbon registries do you accept?

We sell credits issued by Verra (VCS), Gold Standard, Puro.earth, the American Carbon Registry (ACR), the Climate Action Reserve (CAR), Isometric, the International Carbon Registry (ICR), Regen Registry, Thailand’s T-VER, and the Universal Carbon Registry (UCR), among others. We also screen every project against the ICVCM Core Carbon Principles, a cross-registry quality benchmark.

Do you issue your own carbon credits?

No. We are an aggregator and reseller, not a registry. We source verified credits at wholesale, curate them, retire them on the source registry, and issue you a certificate — but the credits themselves are issued and tracked by the standards above.

How do you check credit quality?

On top of the registry label, we screen each project against the ICVCM Core Carbon Principles and independent third-party ratings such as BeZero and Sylvera before it enters our catalogue.

Where do you source credits?

We buy at wholesale from established marketplaces and exchanges — Carbonmark, Patch, and Xpansiv (CBL) — and from selected, vetted project developers.

How can I verify a credit was retired?

Every retirement generates an immutable public serial number on the source registry, and every certificate links to a public verification page showing that record. You can confirm it independently, without us.
