Protocols

One method per intervention.

A protocol says exactly how a type of project is measured, verified and certified. Public, versioned, and reviewed by independent experts.

02In short

What a protocol is for.

To speed up the adoption of climate and environmental solutions, the market created an incentive: the certificate. Its value rests on the protocol behind it, the accounting standard for the impact.A certificate is worth only the protocol behind it: the accounting standard for the impact.

  1. A protocol fixes what is measured, how, and the evidence required.
  2. Without a robust protocol, no credible certificate.
  3. Without a credible certificate, no easy access to the market.

03A key to the market

Voluntary standards open the market.

A recognised method makes your impact comparable and verifiable. Buyers, funders and regulators then speak your language: protocols become a key to the market.A recognised method makes your impact comparable, verifiable and fundable.

  1. Project developers and ecotechs. Proof that holds up, to sell, raise funds or answer a tender.
  2. Companies. Comparable volumes, ready for their water strategy and reporting.
  3. Funders. A verified impact, easier for sustainable finance to fund.

Credible by design.

Built on the references auditors, regulators and funders already use. Nothing that matters is self-declared.

06Structure

Same structure, every time.

Every protocol follows the same six steps, in the same order: a buyer, a funder or a verifier always knows where to look.

  4. 04Calculation

07How a protocol is made

Reviewed before it is published.

  1. 01Drafted by Veracity's normative team.
  2. 02Reviewed by domain experts before publication and at every revision.
  3. 03Opened to public consultation for integrity changes.
  4. 04Versioned: a certificate always names the version it used.

+Questions

Which projects qualify?

Measurable projects that go beyond business as usual and legal duty. Each protocol sets its own eligibility rules.

What if my project type is not listed?

Become a founding pilot. Founding pilots shape new protocols with us.

Who writes the protocols?

Veracity's normative team drafts them; domain experts review them before publication and at every revision.

What happens when a protocol changes?

A new version is published. Each certificate names the version it used, so past results stay valid and traceable.

What does “Public consultation” mean?

The draft protocol is open for public comment before it is published. Protocols dated Q1 2027 or Q3 2027 are being finalised with founding pilots until then.
