Our most frequently asked questions 

What are Proba Impact Units?

Proba Impact Units are tradable certificates each representing one tonne of carbon dioxide equivalent (CO₂e) that is removed or reduced as a result of a sustainability project. We offer the opportunity for reporting companies to claim these credits in their sustainability report, using them to lower the Scope 3 emissions associated with the purchased products. For most companies, Scope 3 emissions represent more than 75% of their total emissions, meaning that reducing them is fundamental to any Net Zero strategy.

How do you create Proba Impact Units?

The process involves several key steps:

  • Companies achieve lower emissions than business as usual through sustainability projects.
  • These reductions are verified by an independent third party, based on the quantification protocols in our methodologies.
  • Verified reductions are then transformed into Proba Impact Units.
  • Supply chain partners can purchase these units and report reduction in their Scope 3 footprint.
Why do I need Proba Impact Units in the first place?

Proba Carbon Credits are crucial as they signify quantifiable and verified emissions reductions within the supply chain. They facilitate direct investment into sustainability projects, allowing companies to credibly reduce their Scope 3 emissions and support  decarbonization initiatives.

How does Proba ensure the integrity of Impact Units to avoid double counting?

To maintain the integrity and credibility of Proba Impact Units, Proba’s blockchain powered registry ensures that each Impact Unit is claimed only once, eliminating double counting. This rigorous tracking system guarantees that each unit of emission reduction is uniquely accounted for and prevents any possibility of double claiming.

Why is third-party verification crucial for Proba Impact Units?

Third-party verification, by accredited auditors, ensures that the emission reductions claimed through Proba Impact Units are real, measurable, and exceed baseline environmental performance. This validation process builds trust among all stakeholders using the Proba Insetting Service, ensuring the credits' authenticity and environmental impact.

How can companies benefit from purchasing Proba Impact Units?

Purchasing Proba Impact Units allows companies to directly invest in the decarbonization of their supply chain, reflecting a tangible commitment to sustainability. It enables them to meet their Scope 3 reduction targets more effectively, leveraging verified reductions achieved by their suppliers to enhance their own environmental credentials.

Can Proba Impact Units drive further decarbonization in the supply chain?

Absolutely. By facilitating the transaction of verified emissions reductions as Proba Impact Units, this incentivizes both suppliers and customers to engage in and scale further decarbonization efforts. Suppliers are motivated to implement sustainable practices, and customers can directly support these efforts, which helps to get us to a low-carbon economy quicker.

How do Proba Impact Units align with global climate goals and sustainability standards?

Proba Impact Units are designed to align with stringent global climate goals and the reporting standards of the GHG Protocol and SBTi. By ensuring that emissions reductions are real, verifiable, and impactful, Proba supports the global agenda to mitigate climate change, providing a credible and transparent tool for companies to contribute to a sustainable future.

What is the difference between offset credits and inset credits?

Offset credits and inset credits (sometimes referred to as Impact Units) offer two distinct pathways for companies to address their environmental impact, especially concerning greenhouse gas emissions. 

Offset credits allow for the compensation of unavoidable emissions by supporting external projects that reduce CO₂ or other GHGs. This can involve funding renewable energy initiatives, reforestation projects, or other endeavors aimed at absorbing GHGs. Typically, one carbon offset credit is equivalent to the reduction of one metric tonne of CO₂ or its GHG equivalent. 

On the other hand, inset credits focus on investments made within a company’s own value chain to decrease emissions. This approach emphasizes enhancing the efficiency and sustainability of internal processes, supply chains, and operations. Specifically, it targets the reduction of Scope 3 emissions, which encompass indirect emissions, such as those from the production of purchased goods and services, the life-cycle of products, and operations of investments not directly owned or controlled by the company.

Money: market price of Impact Units

How much do Impact Units cost and how much do they sell for?

The market price of Impact Units varies based on the market demand, the specific project from which the Impact Units are generated, and the volume of Impact Units being purchased. Prices are influenced by the complexity, location and impact of the emission reduction projects. If the Impact Units aren't sold directly to your supply chain partners, Proba can connect you with trusted market makers and brokers to ensure you get a fair price for them.

Market: buyers and the meaning of Impact Units

Who is going to buy the Impact Units, and what do they actually mean to these offtakers?

Proba Impact Units are primarily purchased by businesses seeking to meet their sustainability targets, especially those related to Scope 3 emissions. These buyers are active in your supply chain. For these offtakers, purchasing Proba Impact Units means they are directly contributing to tangible, verified emission reductions within their supply chain. This not only helps them meet regulatory requirements and corporate sustainability goals but also positions them as leaders in the global shift towards sustainability.

Credibility: trust and double-claiming

Can you trust your Impact Units? What about the risks of double-claiming? Is Proba credible?

Trust and credibility are the foundations of Proba's Insetting Service. We ensure the integrity of our Impact Units through rigorous, independent third-party verification processes that confirm the real-world impact of emission reductions. To mitigate the risk of double-claiming, we employ a robust tracking and auditing system that meticulously records the issuance, transfer, and retirement of Impact Units on a public blockchain. Proba's credibility is backed by adherence to international ISO standards and our commitment to transparency, including an independent advisory board, which governs our Standard. This ensures that stakeholders can confidently participate in our program.

Process: getting started with Proba Impact Units

Where do I start? What do I need? What needs to be done? Who is involved?

Step 1: Describe your GHG reduction initiatives
Provide details about your GHG reduction, removal, or avoidance initiatives, including their expected GHG impact. We'll assist in registering your project on our platform and the quantification of the impact based on our methodologies.
