We are officially in a new era for environmental and carbon emissions reporting. As of early 2026, the European Union Batteries Regulation (EUBR) has transitioned from a legislative roadmap to a rigorous enforcement reality. For manufacturers and industrial operators, carbon emissions are no longer a peripheral ESG metric; they are now a mandatory passport to the European market. With the introduction of the verified carbon footprint declaration, the EU is moving past simple estimates toward a high-fidelity data standard that requires site-specific primary data for every battery model and production plant.
The implications for global supply chains are immediate and profound. Starting in 2026, all rechargeable industrial batteries with a capacity greater than 2 kWh must provide a verified carbon footprint. This is the first domino in a sequence that leads to the 2027 Digital Battery Passport, which will require real-time synchronization between Battery Management Systems (BMS) and reporting platforms. For companies accustomed to industry average emission factors and spend-based data, the new mandate represents a massive shift in how they need to consider carbon emissions as part of the license to operate. The automotive industry in particular is impacted by this regulation as it shifts to EVs given compliance now requires data from Tier 3+ suppliers, the deep-tier partners where the majority of embodied carbon often hides.
At Muir, we see this regulatory shift not just as a compliance hurdle, but as a strategic inflection point. The companies already managing the transition in this new landscape will be the organizations that move beyond manual reporting to automating product intelligence through high-fidelity supply chain mapping and folding in strategic design decisions. By centralizing carbon data today, manufacturers can treat compliance as a "moat," ensuring their products are compliant while optimizing their operations for a low-carbon future. With EUBR, the era of best guesses is over; the era of granular, verifiable carbon intelligence is here.
