Environmental Liability and the EU Battery Regulation: 2026 Milestones

Introduction

The European Union’s Battery Regulation (Regulation (EU) 2023/1542 of the European Parliament and of the Council of 12 July 2023 concerning batteries and waste batteries) represents one of the most ambitious pieces of environmental product legislation enacted by the EU in recent years. Replacing the earlier Battery Directive 2006/66/EC, the Regulation establishes comprehensive requirements covering the entire lifecycle of batteries—from raw material sourcing and manufacturing to labelling, performance, collection, recycling, and end-of-life management.

The year 2026 is a critical milestone year for the Battery Regulation, as several key obligations become applicable between February and August. This article provides a detailed examination of the 2026 milestones, the compliance obligations imposed on economic operators, the enforcement environment in Hungary, and the practical steps that companies must take to avoid regulatory exposure.

Overview of the EU Battery Regulation

Scope and Categories

The Battery Regulation applies to all batteries placed on the EU market, regardless of their shape, volume, weight, design, material composition, chemistry, use, or purpose. It establishes five categories of batteries, each subject to differentiated regulatory requirements:

1. Portable batteries — batteries that are sealed and weighing below 5 kg, not designed for industrial use, and not electric vehicle batteries;
2. Starting, lighting, and ignition (SLI) batteries — batteries used primarily for automotive starting, lighting, and ignition;
3. Light means of transport (LMT) batteries — batteries used in electric scooters, e-bikes, and similar light electric vehicles;
4. Electric vehicle (EV) batteries — batteries used in road vehicles powered wholly or partly by an electric motor;
5. Industrial batteries — batteries designed for industrial or professional use, including stationary energy storage systems.

Legislative Objectives

The Regulation pursues several interrelated policy objectives:

• Ensuring a high level of environmental and human health protection throughout the battery lifecycle;
• Promoting a circular economy for batteries, maximising the recovery and recycling of valuable materials;
• Enhancing transparency in battery supply chains, particularly with respect to the sourcing of critical raw materials (cobalt, lithium, nickel, natural graphite);
• Establishing a level playing field for all economic operators on the EU market, regardless of origin;
• Supporting the competitiveness of European industry in the global battery market.

2026 Milestones: What Changes and When

18 February 2026: Carbon Footprint Declaration for EV and Industrial Batteries

From 18 February 2026, manufacturers of EV batteries and rechargeable industrial batteries with a capacity above 2 kWh must provide a carbon footprint declaration for each battery model placed on the EU market. This declaration must cover the entire lifecycle of the battery, from raw material extraction through manufacturing, transport, and recycling, calculated in accordance with the methodology specified in the delegated acts adopted by the European Commission pursuant to Article 7 of the Regulation.

The carbon footprint declaration must be:

• Made available to the battery purchaser and to downstream economic operators;
• Accessible via the QR code affixed to the battery (which links to the battery’s digital product information);
• Updated whenever there is a significant change in the manufacturing process or supply chain that materially affects the carbon footprint.

18 August 2026: Capacity and Performance Labels

From 18 August 2026, all batteries placed on the EU market must bear a label indicating their rated capacity, in accordance with the technical specifications set out in the delegated regulation adopted under Article 13 of the Battery Regulation. The label must be:

• Visible, legible, and indelible, affixed directly to the battery or, where the battery is incorporated into an appliance from which it cannot be readily removed, on the packaging or accompanying documentation;
• Expressed in standardised units (watt-hours for rechargeable batteries, ampere-hours for non-rechargeable batteries);
• Accompanied by information on the expected battery lifetime under reference conditions.

For EV batteries, the label must additionally include performance and durability information, including the battery’s state of health (SoH) at the time of placing on the market, the number of charging cycles it is designed to withstand, and the expected range under standard test conditions.

This labelling requirement is distinct from the separate energy labelling obligations under the Energy Labelling Regulation (EU) 2017/1369 and is intended to provide consumers and professional users with battery-specific performance data.

Digital Battery Passport: 2026 Pilot Phase

While the mandatory Digital Battery Passport is scheduled for full application to EV batteries from 1 February 2027 (and to LMT batteries and industrial batteries from later dates), 2026 represents a critical pilot phase during which the European Commission is finalising the technical standards and the interoperable data-sharing infrastructure for the passport.

The Digital Battery Passport will contain:

• A unique battery identifier linked to the manufacturer and production batch;
• Information on the battery’s carbon footprint, recycled content, expected lifetime, and state of health;
• Data on the supply chain due diligence performed with respect to critical raw materials;
• Information relevant to end-of-life management, including dismantling instructions and recycling-relevant composition data.

Economic operators placing batteries on the market in 2026 are strongly advised to begin preparing their data collection and management systems to ensure compatibility with the Digital Battery Passport requirements. The European Commission has published preliminary technical specifications, and several industry consortia are developing interoperability standards.

Hungarian Enforcement Environment

Competent Authorities

In Hungary, the enforcement of the Battery Regulation falls within the competence of several authorities, depending on the specific obligation concerned:

• The Hungarian Authority for Consumer Protection (fogyasztóvédelmi hatóság), operating under the aegis of the Government Offices (kormányhivatalok), is responsible for market surveillance of labelling and consumer information requirements;
• The National Inspectorate for Environment and Nature (OKTF) and the county-level environmental inspectorates (környezetvédelmi hatóság) are responsible for overseeing waste management, collection, and recycling obligations;
• The Hungarian Trade Licensing Office (Magyar Kereskedelmi Engedélyezési Hivatal, “MKEH”) oversees product compliance and import controls;
• The National Tax and Customs Administration (Nemzeti Adó- és Vámhivatal, “NAV”) exercises customs enforcement at the point of entry to the EU market.

Enforcement Trends in 2026

Hungarian authorities have signalled a markedly proactive enforcement posture with respect to the Battery Regulation. Several developments are noteworthy:

• Targeted market surveillance campaigns: The consumer protection authorities have announced targeted inspection campaigns for 2026, focusing on the compliance of portable batteries and LMT batteries sold through online marketplaces and in retail outlets;
• Administrative fines: Non-compliance with labelling requirements, failure to provide the carbon footprint declaration, or failure to register with the producer responsibility organisation may result in administrative fines of up to HUF 500 million (approximately EUR 1.3 million) per infringement, with the possibility of cumulative fines for continued non-compliance;
• Product recalls and market withdrawal: Where a battery is found to be non-compliant with safety or labelling requirements, the competent authority may order its withdrawal from the market or, in serious cases, a product recall;
• Criminal liability: In cases involving deliberate falsification of environmental data, fraudulent labelling, or systematic evasion of waste management obligations, criminal proceedings may be initiated under the Hungarian Criminal Code (Büntető Törvénykönyv, Act C of 2012), specifically the offences of environmental damage (környezetkárosítás, Section 241) and consumer fraud (fogyasztók megtévesztése, Section 417).

Corporate Compliance Requirements

Obligations of Manufacturers

Manufacturers placing batteries on the EU and Hungarian market bear the most extensive compliance obligations under the Regulation. In 2026, these include:

• Conformity assessment: Ensuring that each battery model conforms to the applicable safety, performance, and labelling requirements, and preparing the relevant technical documentation;
• CE marking: Affixing the CE marking to compliant batteries, together with the identification of the notified body (where applicable);
• Carbon footprint declaration: Preparing and maintaining the carbon footprint declaration for EV and rechargeable industrial batteries;
• Capacity label: Ensuring that all batteries bear the required capacity and performance label from 18 August 2026;
• Extended Producer Responsibility (EPR): Registering with a producer responsibility organisation (gyártói felelősségi szervezet) in each Member State where batteries are placed on the market, financing the collection, treatment, and recycling of waste batteries, and meeting the applicable collection targets;
• Supply chain due diligence: Conducting due diligence on the sourcing of critical raw materials (cobalt, lithium, nickel, natural graphite) in accordance with the due diligence obligations set out in Chapter VII of the Regulation, which are aligned with the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas.

Obligations of Importers and Distributors

Importers of batteries into the EU must verify that the manufacturer has carried out the required conformity assessment, that the battery bears the CE marking and required labels, and that the technical documentation is available. Distributors must ensure that the batteries they make available on the market bear the required markings and labels.

Both importers and distributors may be treated as manufacturers for the purposes of the Regulation if they place a battery on the market under their own name or trademark, or if they modify a battery in a way that affects its compliance.

Supply Chain Disruption Risk

The 2026 milestones carry significant supply chain risk for companies that have not yet adapted their compliance processes. Batteries that do not bear the required capacity label as of 18 August 2026 may not lawfully be placed on the EU market. Similarly, EV and industrial batteries without the carbon footprint declaration may not be placed on the market from 18 February 2026.

Companies relying on battery supply from non-EU manufacturers must ensure that their suppliers are aware of and capable of meeting the Regulation’s requirements. Contractual provisions requiring supplier compliance, the right to audit, and indemnification for non-compliance costs are essential elements of supply chain risk management.

Extended Producer Responsibility (EPR) Obligations

EPR in Hungary

Hungary’s implementation of the EPR obligations under the Battery Regulation is governed by Act XLIII of 2000 on Waste Management (a hulladékgazdálkodásról szóló 2000. évi XLIII. törvény) and related implementing decrees. Producers of batteries placed on the Hungarian market must:

• Register with the competent waste management authority and designate a producer responsibility organisation;
• Finance the collection, transport, treatment, and recycling of waste batteries, in proportion to the volume of batteries placed on the market;
• Meet collection targets: The Regulation sets progressively increasing collection targets for portable batteries (63% by the end of 2027, 73% by the end of 2030) and for LMT batteries (51% by the end of 2028, 61% by the end of 2031);
• Report annually on the volumes of batteries placed on the market, collected, and recycled.

Non-compliance with EPR obligations may result in administrative fines, exclusion from the market, and reputational damage.

Practical Steps for Compliance

Companies affected by the 2026 milestones should take the following practical steps:

1. Audit current product range: Identify all battery types and categories within the scope of the Regulation and assess current compliance status;
2. Update labelling: Ensure that all batteries placed on the market from 18 August 2026 bear the required capacity and performance labels;
3. Prepare carbon footprint declarations: For EV and rechargeable industrial batteries, prepare lifecycle carbon footprint declarations in accordance with the Commission’s delegated acts;
4. Review supply contracts: Incorporate compliance obligations, audit rights, and indemnification provisions into contracts with battery suppliers;
5. Register for EPR: Ensure registration with the appropriate producer responsibility organisation in Hungary and in each other Member State where batteries are placed on the market;
6. Begin Digital Battery Passport preparation: Establish the data collection systems and IT infrastructure necessary to generate Digital Battery Passports when the requirement becomes fully applicable;
7. Train staff: Ensure that procurement, quality assurance, logistics, and legal teams are aware of the new requirements and their operational implications.

Conclusion

The 2026 milestones of the EU Battery Regulation represent a step change in the regulatory obligations imposed on companies involved in the battery value chain. The combination of carbon footprint declarations, mandatory capacity labels, Digital Battery Passport preparation, and enhanced enforcement by Hungarian authorities creates a compliance landscape that demands early and systematic action. Companies that delay preparation risk market disruption, regulatory penalties, and competitive disadvantage.
