Battery Passport Carbon Footprint Declaration Delayed

The EU battery passport’s 18 February 2027 deadline has not moved, but the carbon footprint methodology it depends on has: the delegated act needed to calculate and declare a battery’s carbon footprint was targeted for February 2025 and, as of this writing, is still in draft.

Why AuthiChain

• The passport’s other required fields — material composition, state-of-health, recycled content — do not wait on the carbon footprint methodology and can be structured into the signed record now
• The methodology follows the Product Environmental Footprint approach under ISO 14067, so a record built to receive a PEF-style carbon figure does not need re-architecting once the delegated act lands — only the number changes
• A delayed methodology delegated act does not delay the underlying implementing act for the declaration format either — both are still pending, and downstream deadlines move with them

How it works

Issue a unique identifier per unit, anchor its record on-chain for tamper-evidence, and let anyone verify it with a single scan. Plans start at $49/mo.

FAQ

Does the carbon footprint delay push back the February 2027 battery passport deadline?

Not on its own — 18 February 2027 remains the mandate date for the passport itself. The carbon footprint declaration is one required field inside it, and its methodology is what is delayed.

What should we do while the methodology is still in draft?

Structure the passport record now with the fields that are settled — composition, state-of-health, recycled content — and add the carbon footprint figure once the delegated act specifies how to calculate it.
