Environmental Standards EEA 2025: What Companies Operating in Norway, Iceland and Liechtenstein Must Do

Key data

Companies with activity in the European Economic Area (EEA) outside the EU face a regulatory change that is already in force. The Decision 318/2025 of the EEA Joint Committee, adopted on December 5, 2025, amends Annex XX of the EEA Agreement, which regulates the environmental regulations applicable in Norway, Iceland and Liechtenstein.

The practical result is clear: these three countries are required to apply the same environmental regulatory acts of the EU that have been incorporated into Annex XX. For any economic operator with presence or business relationships in those markets, this means an update of environmental compliance requirements.

What does this regulation establish?

The European Economic Area Agreement allows Norway, Iceland and Liechtenstein to participate in the EU internal market without being Member States. To do so, they must incorporate relevant European legislation into their legal systems through decisions of the EEA Joint Committee.

Decision 318/2025 updates Annex XX, which is the specific annex dedicated to the environment within the EEA Agreement. This update incorporates new EU regulatory acts on environmental matters, extending their application to the three non-EU EEA countries.

In practical terms, any EU environmental regulation that has been incorporated into Annex XX becomes mandatory in the three EEA countries, with the same scope as in EU Member States.

Economic and operational impact

The main impact is not a new fee or direct penalty: it is the expansion of the environmental compliance perimeter for companies with cross-border activity in the EEA.

The most relevant operational consequences are:

• Adaptation of production processes in facilities located in Norway, Iceland or Liechtenstein to comply with new incorporated environmental requirements.
• Review of supply chains involving suppliers or customers in these countries, especially in industrial or energy sectors.
• Update of environmental documentation and certifications necessary to operate or export to these markets.
• Possible adaptation costs in waste management companies operating under regulatory frameworks that now align with more demanding European standards.

The fact that the decision entered into force on December 5, 2025 and was published on April 16, 2026 means that the compliance period has already begun. Companies that have not initiated their adaptation process are accumulating time of non-compliance.

Who does it affect?

This regulation has direct effect on the following business profiles:

• Industrial companies with facilities or subsidiaries in Norway, Iceland or Liechtenstein subject to EU environmental regulation.
• Energy sector operators with activity in the three EEA countries, where EU environmental regulation is especially relevant.
• Waste management companies operating in these markets or providing services to customers located in them.
• Spanish and European exporters selling products or services to companies in Norway, Iceland or Liechtenstein and must demonstrate environmental compliance.
• Business groups with cross-border structure in the EEA that manage regulatory compliance centrally.
• Environmental compliance advisors and consultants serving clients with activity in these countries.

Practical example

A Spanish industrial company with a subsidiary in Norway that manages process waste must verify the following:

Until Decision 318/2025, the Norwegian subsidiary applied the EEA environmental regulations in force until that date. With the update of Annex XX, the new EU regulatory acts on waste management that have been incorporated become mandatory in Norway as well.

This means that the group's compliance officer must:

• Identify which specific regulatory acts have been incorporated into Annex XX through this decision.
• Assess whether the Norwegian subsidiary's operations already comply with those requirements or require adaptations.
• Update internal procedures and environmental compliance documentation to reflect the new applicable framework.

If the company also exports products to Iceland and the Icelandic customer requires certification of environmental compliance in accordance with European standards, Decision 318/2025 strengthens the regulatory basis for that requirement, as it is now integrated into the EEA legal system.

What should companies do now?

1. Identify if you have activity in Norway, Iceland or Liechtenstein in industry, energy or waste management sectors. If so, this regulation directly affects you.
2. Review which EU environmental regulatory acts have been incorporated into Annex XX through Decision 318/2025, accessing the full text in the EU Official Journal.
3. Assess the current level of compliance of your operations in those countries against the new incorporated requirements. Entry into force was December 5, 2025, so the deadline is already running.
4. Update procedures, certifications and environmental documentation in affected facilities or subsidiaries to align with now-required European standards.
5. Inform compliance and operations teams in affected EEA countries about regulatory changes and their practical implications.
6. Consult with a specialist advisor in EEA environmental regulation if your company's activity in these countries is significant or if you operate in sectors with high environmental regulatory burden.
