Automotive Compliance 2026: Battery Passport and CSRD — A Complete Guide for Suppliers
European automotive suppliers face a dual regulatory shock in 2026-2027: the battery passport (February 2027) and CSRD sustainability reporting. Learn how to prepare, align data collection, and automate compliance across both frameworks.
TL;DR: The European automotive industry faces an unprecedented regulatory convergence in 2026-2027. The battery passport (Regulation EU 2023/1542) becomes mandatory in February 2027, while CSRD sustainability reporting is already rolling out across the supply chain. Both frameworks demand the same underlying data: carbon footprint, material origin, recyclability, and supplier compliance. This guide shows you how to tackle them simultaneously rather than doubling your workload.
The Dual Regulatory Shock Facing Automotive Suppliers
The 2026-2027 horizon marks a turning point without precedent for the European automotive industry. Two major obligations are coming into force within months of each other:
| Regulation | Deadline | Scope |
|---|---|---|
| Battery Passport (EU 2023/1542) | February 2027 | Every battery > 2 kWh placed on the EU market |
| CSRD (2022/2464) | 2025-2028 (staggered) | Sustainability reporting for large enterprises and their value chains |
Although distinct, these two regulations impose enhanced traceability of data across the entire supply chain. The same datasets — composition, carbon footprint, material origin — serve both obligations. Smart suppliers are building unified data platforms rather than siloed compliance projects.
CSRD 2026: What Automotive Suppliers Must Report
The Corporate Sustainability Reporting Directive (CSRD) applies progressively:
- 2025: Companies already subject to NFRD (> 500 employees) — reporting on 2024 data
- 2026: Large enterprises (> 250 employees, > €50M turnover or > €25M balance sheet) — reporting on 2025 data
- 2027: Listed SMEs — reporting on 2026 data
Tier-1 and Tier-2 automotive suppliers crossing these thresholds are directly affected. But even smaller suppliers feel the pressure: OEMs and large system integrators are cascading data requests down the supply chain to feed their own CSRD reports.
Key CSRD Data Points for Automotive
- E1 — Climate Change: Scope 1, 2, and 3 carbon emissions, including battery production-related emissions
- E2 — Pollution: Hazardous substances, water and air emissions from production sites
- E5 — Resource Use: Critical raw materials, recycled content rates, circularity metrics
- S2 — Workers in the Value Chain: Social conditions at raw material suppliers (cobalt, lithium extraction)
Battery Passport 2027: Requirements for Manufacturers
The digital battery passport, mandated by Regulation (EU) 2023/1542, requires for each battery:
- A unique identifier linked to a physical QR code on the product
- Composition data: chemistry, capacity, energy density
- Lifecycle carbon footprint: declared from 2025, third-party verified from 2031
- Raw material traceability: origin of lithium, cobalt, nickel
- Recycled content rate: mandatory disclosure
- State of Health (SoH): updated periodically throughout the battery life
From 18 February 2027, any battery without a compliant passport cannot be placed on the EU market.
The Overlap: Why One Data Platform Serves Both Frameworks
Although CSRD and the battery passport are separate legal instruments, their data requirements converge remarkably:
| Data Point | Used in CSRD | Used in Battery Passport |
|---|---|---|
| Carbon footprint (Scope 1, 2, 3) | ✅ E1 — Climate | ✅ Mandatory field |
| Raw material origin | ✅ E5 — Resources | ✅ Traceability requirement |
| Recycled content rate | ✅ E5 — Circular Economy | ✅ Regulatory obligation |
| Supplier compliance | ✅ S2 — Value Chain | ✅ Certification chain |
| Quality control processes | ✅ G1 — Governance | ✅ CE marking support |
This convergence allows mutualisation of effort: a single data collection and structuring platform can feed both obligations, cutting preparation time by up to 60%.
A 4-Step Methodology for Dual Compliance
Step 1: Map Your Existing Data
Before building anything, audit what you already have in your information systems.
For the battery passport: BMS data, supplier technical sheets, material certificates, production records.
For CSRD: Environmental data from sites, social indicators, procurement and supply chain data, existing ESG reports.
Step 2: Structure Supplier Data Collection
Both regulations require upstream data. Deploy standardised questionnaires and supplier portals to collect efficiently:
- Raw material origin and extraction methods
- Upstream carbon footprint estimates
- Social and environmental certifications
- Recycled content and circularity data
Step 3: Automate Report Generation
Manual data collection accounts for 60 to 80% of compliance preparation time. AI-powered automation enables you to:
- Extract data from supplier documents (PDF, Excel, ERP) without manual entry
- Structure it into regulatory formats (ESRS for CSRD, passport specifications)
- Validate completeness and consistency before submission
- Generate compliant reports and QR codes
Step 4: Build Sustainable Governance
Compliance is not a one-off project. It requires durable governance:
- A dedicated compliance officer
- Periodic data update processes
- Internal controls and audit trails
- Continuous regulatory monitoring

FAQ
Are all automotive companies affected by CSRD?
No, only those exceeding the directive's thresholds (> 250 employees with > €50M turnover or > €25M balance sheet) are directly subject. However, OEMs and Tier-1 suppliers are requesting data from their entire supply chain, indirectly impacting SMEs and smaller suppliers.
What are the penalties for non-compliance?
For the battery passport: vehicles with non-compliant batteries cannot be marketed in Europe. For CSRD: significant fines, reputational sanctions, and in some member states, restrictions on dividend distribution.
Can CSRD and battery passport data collection be combined?
Yes, and it is strongly recommended. Carbon footprint, material origin, and recycled content data serve both obligations. A unified collection and structuring platform avoids duplicated effort and reduces supplier fatigue.
How should I prepare supplier data collection?
Start sensitising your strategic suppliers to regulatory requirements now. Integrate adapted contractual clauses and deploy standardised data collection tools. The earlier your supply chain is aligned, the smoother your compliance journey.
Have ESRS standards been modified recently?
Yes, in July 2025 the European Commission published temporary adjustments significantly reducing the number of mandatory indicators (approximately 60-70% fewer). These modifications apply to reports published from January 2026 onwards.
What is the difference between the battery passport and CSRD?
The battery passport is a technical document specific to each battery, required for market placement. CSRD is an annual sustainability report covering all ESG issues of the enterprise. Both are distinct but complementary in the European transparency framework.
