Questions people actually ask us.

Removal only. We do not list avoidance or reduction credits at all. Every tonne on the platform represents carbon physically taken out of the atmosphere and stored for a stated duration.

Biochar, enhanced rock weathering, direct air capture with geological storage, and native-species reforestation. We also work with blue carbon and bio-oil sequestration on a case-by-case basis.

Melbourne, with project sites across 24 countries.

Entirely pathway-dependent. Reforestation runs $45–95, biochar $120–180, enhanced weathering $180–320, direct air capture $380–600. Most buyers land on a blended portfolio in the $90–160 range. Multi-year offtake reduces those figures meaningfully.

Spot purchases start at 100 tonnes. Offtake agreements typically start at 1,000 tonnes per year, which is where the pricing and supply-security advantages actually appear. Below 100 tonnes we will usually point you somewhere better suited.

Yes — all of it, before you commit anything. Measurement data, methodology version, verifier attestation, and site details are public for every project. You can audit a project fully without talking to us.

Retirement records export in formats aligned with GHG Protocol and SBTi guidance, and our API pushes directly into most carbon accounting platforms. For custom stacks, the REST endpoints are documented and stable.

We hold a buffer pool funded by a percentage of every issuance across all pathways. If a confirmed reversal affects credits you have retired, replacements are drawn from the pool at no cost to you. The pool balance is published monthly.

Yes, and we encourage it. Every offtake agreement includes site access rights. We coordinate visits directly with developers and can arrange technical walkthroughs with the verifier who audits the site.

Nothing up front. Instrumentation, verification, and platform costs are recovered as a percentage of issuance — so we are only paid when you are. The percentage varies by pathway and volume, and we quote it before you commit to anything.

Median four weeks: three days for eligibility screening, about a week for methodology review, two weeks to install and calibrate instrumentation, then your first measured batch.

You own the operational data. Measurement data tied to issued credits is published — that is the whole point of the model, and it is stated plainly in the agreement. Nothing about your commercial terms, costs, or internal operations is ever published.

Yes, unless you have signed a specific exclusive offtake. Most developers run a mix. We only require that credits measured on our instrumentation are not also issued through another registry.

Common and not a barrier. What matters is that the removal mechanism is sound and measurable. We have onboarded projects at pilot scale and structured pre-payment to fund build-out.

Three filters: is the removal physically real and measurable, is it durable for a defined period, and are community and land-rights safeguards genuinely in place. We turn down more applications than we accept, and we tell you why.

We do, from a pooled fee collected at issuance. Developers never select or pay their own verifier, and verifiers rotate across projects. It is the same principle that separates auditors from the companies they audit — structural independence rather than a stated commitment.

Traditional registries record what developers submit. We generate the measurement ourselves through instrumentation we install and maintain, assign verifiers by rotation, and publish the raw data alongside every credit. The registry function is the last step, not the whole product.

Our methodologies are built against the ICVCM Core Carbon Principles and our claims guidance follows the VCMI Claims Code. We also structure retirement records to satisfy GHG Protocol reporting and the emerging EU CRCF framework.

Credits measured on our instrumentation cannot be issued through another registry — that is contractual with every developer. Retirement is permanent and public, so any attempt to resell a retired credit is visible to anyone checking.

As the science requires, typically once or twice a year per pathway. Every version is retained, and credits stay linked to the methodology version in force when they were issued.
