Batteries are often discussed in the context of electric vehicles, but their role in the future economy extends far beyond mobility. Batteries are the heart of future energy systems. They store renewable energy, help balance electricity grids, provide backup power for critical infrastructure and support the electrification of transport, buildings and industry.
This unique ability to connect the transport, energy and building sectors makes batteries a key enabler of safe, sustainable and resilient energy systems.
The European Commission sees the build-up of a European battery industry as one of its strategic priorities for Europe’s clean and digital transition. In support of this ambition, the Commission launched the Battery Booster Facility, a program designed to support the expansion of battery cell production in Europe.
The trajectory is clear: batteries are becoming a critical technology for Europe’s energy transition, industrial competitiveness and strategic autonomy. But sustainable growth in the battery sector depends not only on the availability of batteries. It also depends on how batteries are manufactured, used, collected, recycled and integrated into circular value chains.
What companies need to know about the EU Battery Regulation
The EU Battery Regulation (EU) 2023/1542 creates a harmonized framework for batteries placed on the European market, whether they are produced in the EU or imported. The regulation applies throughout the battery value chain. It affects battery manufacturers, cell and module suppliers, automotive and EV manufacturers, industrial battery producers, electronics manufacturers, importers, distributors, recyclers and upstream material suppliers.
It also affects non-EU companies that place batteries or battery-containing products on the EU market. For example, suppliers of battery cells and modules may need to provide battery manufacturers with the documentation and data required for carbon footprint calculations, battery passport information and future reporting obligations.
The EU Battery Regulation replaces the previous Batteries Directive and introduces a broader framework for batteries and waste batteries. Key sustainability requirements include:
- restrictions on hazardous substances, including cadmium, lead and mercury
- carbon footprint declarations, performance classes and future maximum thresholds
- recycled content requirements
- extended producer responsibility
- collection and recycling targets
- material recovery targets for key battery materials
- digital battery passport requirements for certain battery categories
The regulation is being phased in over time. Some requirements already apply, while others depend on delegated or implementing acts before they become fully operational. This phased structure makes readiness planning especially important for companies managing multiple products, production sites or suppliers.
What are the EU Battery Regulation carbon footprint requirements under Article 7
Article 7 introduces carbon footprint requirements for certain battery categories. These requirements are expected to evolve in phases, moving from carbon footprint declarations to performance classes and eventually maximum carbon footprint thresholds.
A draft version of the delegated act for the carbon footprint of electric vehicle batteries was published by the European Commission in 2024. However, a final version has not yet been adopted. The draft has been discussed by stakeholders, particularly around electricity modeling, treatment of electricity contracting instruments and alignment with other regulatory approaches.
For companies, this is not simply a reporting exercise. Battery carbon footprint calculations require reliable data, consistent methodology and documentation that can support verification and future reporting obligations.
Companies will likely need to manage:
- product-specific and site-specific production data
- supplier and upstream material data
- energy and process data
- transport and logistics information
- life cycle inventory data
- end-of-life assumptions
- methodological documentation
- quality checks and verification-ready reporting
Because battery carbon footprint results can be sensitive to methodological choices, companies should begin identifying data gaps and calculation risks early.
Why companies should prepare despite uncertainty
Some of the final calculation details are still under discussion. Key areas of debate include electricity modeling, the use of power purchase agreements and guarantees of origin, alignment with other regulatory approaches and practical implementation challenges.
At the same time, there is little doubt about the overall direction. Carbon footprint reporting is clearly set in the regulation for applicable batteries. The question is less whether companies will need to prepare and more how quickly they can build the required data, modeling and reporting capabilities.
The JRC carbon footprint rules for electric vehicle batteries and the current draft methodology provide a useful basis for preparation. Companies can use this time to build internal capability, test data availability, create repeatable LCA workflows and prepare documentation processes.
Waiting until every detail is finalized may leave too little time to operationalize compliance. Early preparation can help companies reduce rework, improve audit readiness and respond more confidently as final requirements are published.
How the battery passport connects to carbon footprint reporting
The digital battery passport is another major requirement under the EU Battery Regulation. It is expected to apply from February 18, 2027, for electric vehicle batteries, light means of transport batteries and rechargeable industrial batteries above 2 kWh.
The battery passport is designed to increase transparency across the battery life cycle by making key product, sustainability and traceability information accessible in digital form. Carbon footprint information is one of the data points connected to this broader transparency framework.
For companies, this means carbon footprint reporting and battery passport preparation should not be treated as separate workstreams. Both require structured product data, supplier information, documentation and governance. Building these foundations early can support both regulatory readiness and long-term product sustainability management.
Companies preparing for battery passport requirements may also need to consider how battery-related data connects to broader Digital Product Passport and ESPR readiness.
How companies can prepare now
Companies can take practical steps now, even while final calculation rules continue to evolve.
Assess product and market exposure
Start by identifying which batteries, battery systems or battery-containing products are placed on the EU market. Map the relevant battery categories, production sites, suppliers and business units that may be affected.
Build a reliable data foundation
Battery carbon footprint calculations depend on high-quality data. Companies should assess whether they can access production data, energy data, material inputs, supplier information and life cycle inventory data. Where data is missing, they should define a plan for supplier engagement or data improvement.
Prepare scalable LCA workflows
Manual, one-off calculations may not scale across multiple products, plants or reporting cycles. Companies should develop repeatable LCA workflows that can be updated as methodology evolves and applied across battery portfolios.
This is where Sphera’s Product Sustainability experts can help companies move from ad hoc calculations to structured, defensible and repeatable reporting processes.
Identify methodological risks early
Battery carbon footprint results can be influenced by system boundaries, allocation rules, electricity modeling, recycled content assumptions and end-of-life treatment. Early review of these methodological issues can help avoid costly rework later.
Create audit-ready documentation
Compliance will require more than a final carbon footprint number. Companies need documentation that explains data sources, assumptions, calculation methods, quality checks and responsibilities.
Align carbon footprint and battery passport readiness
Carbon footprint data will form part of a broader digital product data landscape. Companies should align Article 7 preparation with digital battery passport planning, supplier data governance and internal sustainability data processes.
