MARKET FUNDAMENTALS

One unit. Many different stories.

Understand the instrument before comparing the opportunity.

Start with the accounting unit.

A Verra Verified Carbon Unit represents one tonne of carbon dioxide equivalent reduced or removed. This common unit does not make all project types interchangeable.

REDUCTIONS & AVOIDANCE

A different emissions outcome

A project is assessed against a counterfactual baseline. Examine whether that baseline and the claimed additional impact are credible.

Review additionality
REMOVALS

Taking carbon out

Biological or engineered approaches remove CO₂. Assess storage duration, monitoring and the consequences of reversal.

Review permanence
USE & ELIGIBILITY

Purpose shapes the requirements

Voluntary procurement, international transfers and aviation requirements are different pathways. A label alone cannot establish eligibility for your use.

Read the source notes

From project activity to retirement

  1. Define & document

    Methodology, boundary, baseline and safeguards establish the project case.

  2. Validate & verify

    Independent assessment examines the activity and measured mitigation.

  3. Issue & transfer

    A registry records issued units and their ownership history.

  4. Retire & disclose

    Retirement records the use of a credit; the claim still needs its own justification.

Use registry documentation to check the actual project and units. [4] Gold Standard
