Verra

Verra is a Washington, D.C.-based nonprofit standards body that develops and manages the world's leading certification programs for climate action and sustainable development. Its flagship program, the Verified Carbon Standard (VCS), is the most widely used voluntary greenhouse gas crediting program globally, with more than 2,579 registered projects across 132+ countries and over 1.3 billion Verified Carbon Units (VCUs) issued. Verra also operates the Climate, Community & Biodiversity Standards (CCB), the Sustainable Development Verified Impact Standard (SD VISta), the Plastic Waste Reduction Standard (PWRP), the Scope 3 Standard Program, and the Jurisdictional and Nested REDD+ (JNR) framework. The Verra Registry at registry.verra.org is the system of record for projects, methodologies, issuances, retirements, and the AFOLU pooled buffer account across these programs; project documentation, public comment periods, and credit-lifecycle records are all surfaced through that registry. Verra recently launched VCS Version 5, modernizing program operations, strengthening safeguards, and clarifying credit rights. Verra does not publish a public developer API, OpenAPI specification, SDK, or GitHub organization; programmatic data access is limited to the registry's web interface and filtered report exports, and there is no open-source code or machine-readable spec catalog associated with the organization.

Verra is profiled on the APIs.io network. Tagged areas include Carbon, Carbon Credits, Carbon Markets, Voluntary Carbon Market, and Carbon Registry.

Verra’s developer surface includes product news, YouTube channel, engineering blog, and 19 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/verra-org: open an issue to ask a question, or submit a pull request to add artifacts.
