Disclosures
Voluntary carbon market disclosures.
Published in accordance with California's Voluntary Carbon Market Disclosures Act (AB 1305, Health & Safety Code §§ 44475–44475.2). This page sets out what we sell, what we don't claim, and the full record of every offset batch we retire.
Policy statements last updated June 9, 2026. The project record below updates automatically as batches are retired, and is reviewed at least annually.
Scope
Two products. Only one is a carbon offset.
The distinction matters legally and practically, so we state it plainly before anything else.
Offsets
A voluntary carbon offset. AB 1305 applies.
We purchase verified carbon credits and retire them in a public registry on the subscriber's behalf. Retirement means the credit is permanently withdrawn and cannot be resold or counted again. Every batch is disclosed in the project record below.
Frontier
Not a carbon offset. No credit is issued.
Frontier contributions fund early-stage energy transition projects. They do not generate, convey, or represent a carbon credit, and they confer no ownership, equity, or financial return. Frontier contributions are not carbon offsets and must not be treated as an emissions reduction claim.
Claims
Claims we do not make.
Terrasition does not claim that it, its operations, or its products are carbon neutral, net zero, or have achieved significant reductions in greenhouse gas emissions. We make no such claim about ourselves, and we do not sell one.
A subscriber who purchases Offsets receives documentation of verified credits retired on their behalf, and may rely on that public registry record for their own reporting. Any claim a subscriber chooses to make is their claim, supported by the registry, not a claim Terrasition makes for them.
Because we make no net zero, carbon neutral, or emissions reduction claim about our own entity or products, the disclosure requirements in Health & Safety Code §§ 44475.1 and 44475.2 are not triggered. This page is published under § 44475, which applies to us as a seller of voluntary carbon offsets.
How our offsets work
Sourcing, verification, durability, and reversals.
Standard and registry
We source credits issued under the Gold Standard, a voluntary carbon standard maintained by an independent non-profit foundation. Credits are held and retired in that registry's public system of record. The registry entry — not this website — is the authoritative record of each retirement.
Third-party validation and verification
Projects are validated and their emissions reductions or removals verified by accredited third-party bodies under the standard's own rules, independently of Terrasition. We do not self-verify, self-certify, or estimate reductions ourselves. Where the verifying body is recorded for a batch, it is named in the project record below.
Credit types
Our pool contains both avoided emissions and carbon removals. The two are not interchangeable: an avoided emission prevents a release that would otherwise have occurred, while a removal takes carbon out of the atmosphere and stores it. Each batch in the project record states which category it falls into.
Durability and reversal risk
Avoided emissions have no durability period in the conventional sense — the emission does not occur, so there is no stored carbon that can later be released. Carbon removals can be reversed if stored carbon returns to the atmosphere. Where a batch carries a durability period, it is stated in the project record.
Accountability for reversals
Two measures apply. First, the registry maintains its own buffer and compliance mechanisms designed to cover reversals across its portfolio. Second, as our own backstop, if a credit retired on a subscriber's behalf is later invalidated or reversed and is not made whole by those registry mechanisms, Terrasition will purchase and retire a replacement credit of equivalent quantity at our own cost. The subscriber is not asked to pay again.
Pooling and attribution
Contributions are pooled and credits retired in batches rather than one transaction at a time, which is how small contributions reach the minimum volumes registries transact in. Each subscriber receives documentation showing their attributed share of a specific batch, traceable to that batch's registry entry.
Project record
Every batch we have retired.
For each batch: the project, its location and type, the protocol used to quantify reductions or removals, the credit category, the project timeline, any durability period, and the registry reference. This record is generated from our retirement data and updates as each new batch is retired.
