Battery passport

What is a battery passport?

As the race toward cleaner energy and electric mobility picks up speed, one thing is clear: batteries are no longer just a component, they’re a cornerstone. And as batteries take center stage in everything from electric vehicles to grid storage, the need for greater transparency, traceability, and sustainability across the battery supply chain has never been greater.

That’s where the battery passport comes in.

This digital tool is set to reshape how we understand and manage the entire lifecycle of a battery: from raw materials to end-of-life recycling. But what exactly is a battery passport in the context of its life cycle, and why does it matter?

Battery passport definition

A battery passport is a digital record that travels with a battery through its entire lifecycle. The battery passport collects and stores key data points about that battery; where its raw materials were sourced, how it was manufactured, how it's been used, and how it should be recycled.

Developed by the Global Battery Alliance and backed by the EU Battery Regulation, the battery passport is designed to:

• Increase transparency in battery supply chains
• Support compliance with environmental and human rights standards
• Enable better recycling and reuse of battery materials
• Reduce the carbon footprint of industrial batteries, including those used in electric vehicles

In essence, it functions like a digital ID for every battery, helping companies and regulators track and verify compliance across value chains.

Why battery passports matter

Modern batteries are built on complex supply chains that span continents. Materials like lithium, cobalt, and nickel often originate in one country, are refined in another, and assembled in a third. This complexity creates blind spots, especially around issues like responsible sourcing, carbon emissions, and end-of-life handling.

Battery passports aim to close these gaps by making key information visible, verifiable, and standardized.

The result? More reliable data, smarter regulation, and better outcomes for everyone involved - from manufacturers and recyclers to regulators and end users.

What information should the battery passport contain?

According to the Global Battery Alliance and EU guidelines, a battery passport will typically include:

• Manufacturing history (including date, location, and technical documentation)
• Carbon footprint data and performance class for the battery
• Material sourcing details, including country of origin and due diligence efforts
• Recycled content and raw materials used
• Usage and performance history, especially for EV batteries
• End-of-life instructions for responsible recycling

The goal is not just to gather data, but to create a standard digital format that can be accessed and interpreted across platforms and stakeholders.

When will battery passports be required?

The EU Battery Regulation introduces a phased implementation of the battery passport starting in 2026, but full technical requirements and operational readiness will evolve over time.

However, 2026 marks the beginning of the rollout - not a universal enforcement deadline. According to the Global Battery Alliance (GBA), the full indicator framework and ESG data guidelines will be published in 2026, while passport models and updates are expected to mature by 2027 and beyond.

The regulation applies to companies operating within or selling into the EU market, meaning global compliance will be critical for most major battery producers and automotive OEMs. The regulation also supports broader sustainability goals through collection targets, minimum recycled content, and carbon footprint disclosures — all of which the battery passport will help document.

How does the battery passport support compliance?

The digital battery passport is emerging as a core tool for ensuring companies meet tightening regulatory requirements. By offering a standardized format for reporting and documentation, it helps companies:

• Meet due diligence and human rights obligations
• Demonstrate alignment with carbon footprint reduction goals
• Prepare for audits and regulatory inspections
• Facilitate cross-border trade by complying with EU battery directive standards

For regulators, the passport provides a single source of truth to evaluate whether companies are meeting compliance benchmarks.

What does this mean for the battery industry?

This is more than a reporting tool. The battery passport signals a shift in how the battery industry operates. For decades, companies have optimized for performance, range, and cost. Now, sustainability and transparency are being added to the list.

With the battery passport in place, companies will need to:

• Map out and document their entire value chain
• Ensure responsible sourcing of critical materials
• Track emissions across the battery lifecycle
• Invest in digital infrastructure and data management

And for consumers? The battery passport could provide information about where their EV battery came from, how it was produced, and how to ensure responsible recycling at end of life.

It’s a big step toward a more transparent, circular economy for batteries.

What are the challenges to implementation?

Like any system-wide change, rolling out battery passports at scale will come with hurdles:

• Data standardization: Creating common formats that all manufacturers and platforms can adopt
• Data privacy: Balancing transparency with proprietary business information
• System integration: Linking multiple digital platforms across suppliers, manufacturers, and recyclers
• Cost and complexity: Especially for smaller players in the supply chain

Despite these hurdles, the direction is clear: digital product passports are coming. And batteries are just the beginning.

Final thoughts: the future of battery transparency

The battery passport isn’t just a compliance exercise. It’s a foundational shift in how we think about materials, data, carbon footprint performance classes and accountability in the global energy system.

By creating a clear and verifiable digital record for each battery, we can:

• Reduce environmental and social risks
• Enable responsible recycling and reuse
• Build trust between companies, consumers, and regulators

As the world moves toward electrification and renewable energy, the pressure on battery supply chains will only grow. Battery passports won’t solve every challenge, but they are a critical first step in making the industry more transparent, efficient, and sustainable, particularly in terms of the battery carbon footprint.

The companies that embrace this shift early will not only stay ahead of regulation - they’ll gain an edge in a market that increasingly values reliability, traceability, and impact. Learn more about sustainable investing with our CME Group webinar.
