What are Impact Units?

Unlike carbon credits, Impact Units specifically track and verify greenhouse gas (GHG) reductions or removals within a company's value chain for accurate Scope 3 emissions reporting.

Proba Impact Units

Using our Proba Standard as a guideline, we make sure that the Impact Units we issue on behalf of our customers represent the accurately stated climate impact and the sustainability claims resulting from them. Our focus is always about quality and ensuring integrity.

The Proba Standard ensures the greenhouse gas impact of a climate project is real, additional, independently verified, unique, not counted or claimed already, and doesn't have negative side effects to the environment and community.

Every Proba Impact Unit is unique and traces back to the real world asset representing 1 tonne of CO₂e (1.000 kg) removed, reduced or avoided.

The Proba Registry manages the ownership and the claims of the Impact Units and supports the required validation and verification workflows. We keep track of the data proving that the sustainability claims are real. 

Our system of assurance is built on a foundation of internationally recognized standards, ensuring credibility and reliability:

  • ISO 14064 - Greenhouse GasesThis standard is integral to our platform as it provides the framework for quantifying, monitoring, reporting and verifying greenhouse gas emissions and removals. By adhering to ISO 14064, we ensure that the carbon reduction, removal and avoidance efforts and the resulting Impact Units generated through Proba are accurate, consistent, transparent, and in line with international best practices.

  • ISO 22095 - Chain of Custody: A framework that standardizes chain of custody implementation, defines protected characteristics, imposes requirements on commercial parties, and outlines different models for supply chain actors

  • ICROA and ICVCM: At Proba, we are dedicated to upholding the highest standards for Impact Units. Our stringent quality criteria guarantee that each unit represents a genuine and verifiable reduction or removal of CO2e. The ICROA Code of Best Practice and the Core Carbon Principles of the ICVCM serve as independent governing bodies for the Voluntary Carbon Market.
