Electric vehicles (EVs) are playing an increasingly vital role in the shift towards a decentralized, renewable energy system. A substantial portion of CO2 emissions is generated during the use phase of these vehicles. To effectively reduce this impact, enhancing the transparency of charging sessions is essential. Achieving this goal requires close collaboration between various companies and industries to ensure a sustainable and efficient transition.
Over the course of our six-month co-innovation project, we have collaborated with experts from the energy and mobility sectors to enhance the transparency of carbon emissions accounting for EVs. Building on the foundation laid by the first phase of the project, REVEAL CO2 1.0, we conducted biweekly workshops and interviews with selected industry partners. These insights helped us develop our green charging registry, Greenistry, addressing one of the key challenges in the area of public charging and emission accounting.
Currently, there is a lack of transparency on the renewable electricity used during public charging sessions of electric vehicles. To provide regulators and customers with insights, fleet operators and OEMs purchase guarantees of origin proving the amount of renewable electricity that is charged without CO2 emissions. At the same time, CPOs also purchase respective documents to declare the amount of renewable electricity used at their charging stations.
We developed a market-based approach that provides transparency on the procurement of renewable electricity. A service provider collects the respective documents from CPOs and provides OEMs and fleet operators with a verified brand-specific certificate on the share of renewable electricity.
Data Collection:
Collecting verified documents on the procurement of renewable electricity from Charge Point Operators (CPOs) to build the registry.
Matching:
Matching OEM charging records with CPO entries and calculating the EU-wide share of energy that is backed by entries in the green charging registry.
Reporting:
The service provider evaluates the data and generates brand-specific reports on the certified share of market-based renewable energy, which can be integrated into your sustainability reporting.
Remuneration:
The OEM pays the service provider a fee for collecting and evaluating the documents in a certified process. The CPO receives remuneration from the service provider for uploading their certificates and updating the status regularly.
Register as an OEM or EMSP and choose from our services in your account:
Green Index: Verifiable proof of how many public charging stations across the EU are already powered by green electricity.
Green Matching: Match charging sessions to CPOs and receive a report on your fleet’s share of green electricity.
Green Navigator: Use our CPO database to guide drivers and fleets straight to charging stations powered by 100% renewable energy.
Upload your certificates securely through our verified process:
1. Register on our platform for green CPOs.
2. Upload proof that you purchase green electricity.
3. We review and confirm your documents.
4. You receive compensation and help reduce charging emissions.
