The EU Batteries Regulation Is Changing: What Battery Manufacturers Need to Know About Their Products
As the EU Batteries Regulation phases in carbon-footprint declarations, performance classes, and digital battery passports, manufacturers selling into Europe will need life cycle data — not just performance specs — to stay compliant and competitive.
by Amos Ncube, Senior Sustainability Advisor
For years, battery manufacturers have been asked increasingly detailed questions about the environmental impacts of their products. What is the carbon footprint of the battery? Where do the materials come from? How much recycled material does it contain? What happens to the battery at the end of its useful life?
Under the European Union's Batteries Regulation, Regulation (EU) 2023/1542, many of these questions are moving from voluntary sustainability reporting toward regulatory requirements for batteries placed on the EU market.
For manufacturers selling batteries into Europe, this means environmental data is becoming part of doing business.
From battery performance to life cycle performance
Historically, battery manufacturers have understandably focused on characteristics such as capacity, safety, durability, charging performance and cost. The EU Batteries Regulation adds another important dimension: life cycle environmental performance.
For electric vehicle batteries, rechargeable industrial batteries above 2 kWh and light means of transport (LMT) batteries, the Regulation introduces carbon-footprint requirements that are being phased in according to battery category and the adoption of supporting EU legislation. The required declaration includes the battery's carbon footprint expressed as kg CO?e per kWh of total energy provided over its expected service life, as well as carbon-footprint results differentiated by life-cycle stage.
That distinction matters.
Understanding the carbon footprint of a battery requires looking beyond the factory gate. Raw material extraction and processing, battery manufacturing, distribution, use and end-of-life can all influence the final result. In other words, manufacturers increasingly need to understand the life cycle of their batteries not simply the emissions from their own facilities.
Carbon footprint is only part of the story
The carbon footprint requirements are not based on an arbitrary corporate carbon accounting method. The EU Batteries Regulation establishes a life cycle-based approach aligned with the European Commission's Product Environmental Footprint (PEF) methodology. The climate change impact is calculated using the applicable Environmental Footprint characterization method and reported as kg CO?-equivalent per kWh of total energy delivered by the battery over its expected service life. This requires manufacturers to understand not only their own manufacturing emissions, but also materials, energy, supply-chain activities, distribution and end-of-life processes. Depending on battery type and timing, requirements also include carbon-footprint declarations and performance classes, recycled-content information, labelling and QR-code requirements, and a digital battery passport.
From 18 February 2027, each EV battery, LMT battery and industrial battery with a capacity greater than 2 kWh placed on the market or put into service must have an electronic battery passport.
The passport creates a mechanism for communicating information associated with the battery throughout its life cycle. Depending on the battery category and applicable requirements, that can include identification and technical information, performance and durability information, and information supporting repair, reuse, recycling and circularity.
For manufacturers, this creates an important practical question: Do you have the data needed to describe the environmental performance of your battery?
The challenge may be the data, not the calculation
Life cycle assessment practitioners know that calculating a carbon footprint is only one part of the exercise. The more difficult task can be developing the underlying inventory.
A battery manufacturer may need information from cathode and anode material suppliers, cell manufacturers, component suppliers, logistics providers and recycling operations. Some information may be readily available. Other data may need to be estimated, modeled or requested from suppliers.
Manufacturers therefore should not necessarily wait until a compliance deadline to begin thinking about LCA.
Building an appropriate life cycle inventory takes time, particularly when information must be collected across a complex global supply chain.
An early assessment can also identify something more valuable than a compliance number: where the carbon footprint actually comes from.
Is it the electricity used during cell manufacturing? The cathode active material? Aluminum? Transportation? Battery lifetime? Recycling assumptions?
Many hotspots are also cost centers—reduce the impacts, reduce the cost. Once the hotspots are understood, manufacturers can begin evaluating realistic opportunities for improvement.
Regulation can become an opportunity
It is easy to look at another environmental regulation simply as another compliance obligation. But good life cycle information can provide value beyond compliance.
The same analysis used to understand regulatory carbon-footprint requirements can help companies compare suppliers, evaluate manufacturing locations and electricity sources, investigate recycled materials, assess design alternatives and identify environmental hotspots.
And as carbon-footprint performance requirements become more developed, understanding those drivers early may become increasingly important for competitiveness in the European market.
The Regulation already establishes a pathway from carbon-footprint declarations, to carbon-footprint performance classes, and eventually to maximum life-cycle carbon-footprint thresholds for specified battery categories, with application dates dependent in part on the adoption and entry into force of the relevant delegated and implementing acts.
So the question may increasingly shift from: "What is our battery's carbon footprint?"
to: "How can we reduce it?"
How EarthShift Global can help
At EarthShift Global, life cycle assessment has been at the core of our work for decades.
For battery manufacturers preparing for the EU Batteries Regulation, we can support the technical work needed to understand and document product environmental performance, including:
- Life Cycle Assessment (LCA) and battery carbon-footprint modeling
- Life Cycle Inventory development and supplier-data strategies
- Identification of environmental hotspots across the battery value chain
- Scenario and sensitivity analysis for materials, manufacturing, electricity, transportation and end-of-life assumptions
- Assessment of recycled-content and circularity strategies
- Technical documentation and interpretation of results to support regulatory preparation
- Independent review and quality assurance of LCA studies
The EU Batteries Regulation represents an important shift in how environmental performance is incorporated into product requirements.
For companies already conducting robust LCAs, much of the thinking behind these requirements will be familiar. For companies beginning this journey, the important thing is to start developing the data, models and internal knowledge needed to understand their products from a life-cycle perspective.
If you manufacture batteries that are sold or may eventually be sold in the European Union, now is a good time to understand what these requirements could mean for your products. EarthShift Global is happy to help you navigate the LCA and carbon-footprint aspects of that journey.
