2026 Battery Passport Pilots

 

2026 BATTERY PASSPORT OPERATIONAL TRIALS

“Transparency is the expectation of tomorrow. We’re providing it today”.

 

The GBA Battery Passport is the global framework for transparent and resilient battery value chains, providing industry, buyers, investors and regulators with the information they need to manage risk, strengthen supply chain resilience, support procurement decisions and demonstrate readiness for evolving market expectations. For civil society stakeholders and rights defenders, the Battery Passport is a groundbreaking accountability tool with whole-of-supply chain coverage. Our alliance works to ensure that the clean energy transition is also a just transition.

Rising to the transparency challenge, seventeen supply chain partnerships formed in early 2026 for the GBA Battery Passport Operational Trials. The cell manufacturers in these partnerships account for 80% of global production – a true industry-wide mobilisation.

Over the second half of 2026, we will be examining case studies of these Operational Trials partnerships, publishing dashboards of 3rd-party verified data on battery supply chain sustainability, presenting our partners’ achievements and seeing their preparations to deploy battery passports at scale.

About the Battery Passport and Operational Trials

The GBA Battery Passport is a sustainability certification building on digital product passport technology. Through the scheme, battery manufacturers and their upstream suppliers report against a harmonised framework for assessing responsible production and sourcing practices, known as the Battery Benchmarks , and calculate product carbon footprints according to the Greenhouse Gas Rulebook .

When that supply chain data is put together at the point of battery production, a digital battery passport is born.

Companies participate in the Operational Trials with a variety of goals. For some, a key motivation is supply chain mapping and supplier engagement, ensuring risk resilience in a complex global sourcing environment. Another key motivation is preparedness for the coming into force of the EU Batteries Regulation in 2027, which mandates robust supply chain due diligence for a range of battery minerals, and carbon disclosures.

Many participants are exploring emerging digital product passport technologies for data authentication and exchange, underpinned by the UN Transparency Protocol and a GBA partnership with the International Trade Centre , and supported by a range of digital providers trialling innovative commercial solutions.

For all participants, a unifying goal is sustainability leadership. Companies recognise the powerful potential of the GBA Battery Passport to demonstrate their commitment to responsible production and sourcing, while address multiple operational challenges simultaneously in a single, integrated digital package.

The Operational Trials build on two previous Battery Passport piloting rounds, in 2023 and 2024 . Each round marks a leap forward in the development of the Battery Passport, in preparation for launch in 2027. New elements in this year’s Operational Trials include:

  • Reporting against the newly-launched GBA Battery Benchmarks – a comprehensive multistakeholder assessment framework for companies’ sustainability management systems, that cross-recognises existing voluntary standards attained by participating facilities. A groundbreaking document for harmonised sustainability reporting in battery supply chains.
  • Full implementation of Digital Product Passport technology, to authenticate and securely exchange reported data, using a decentralised architecture aligned to the United Nations Transparency Protocol and sensitive to commercial companies’ data sharing constraints.
  • Increasingly mature assurance architecture, with a formal Verification Handbook to guide 3rd-party verification bodies, working closely with facilities in the supply chain to ensure data integrity. In an era of green claims scepticism, the Battery Passport puts trust front and centre.
  • Prototype sustainability certification for batteries, based on attainment parameters developed in a multistakeholder environment. Eligibility for sustainability certification rests on management systems for responsible production and sourcing, deployed throughout the upstream supply chain, with suppliers selected for 3rd party verification of claims through risk-based sampling. The parameters and assurance methodology will be assessed for robustness and refined throughout 2026, leading to a full certification scheme launched in 2027.
