Summary

Norway’s Impact Assessment Regulations require EIAs/SEAs for covered plans and projects with potentially significant environmental and societal effects. Developers must prepare assessment documentation as part of the planning and permitting pathway, and authorities must apply procedural rules before approvals are granted. The regime has applied since 1 July 2017 and includes an infringement penalty mechanism (Section 36) for clear procedural breaches and failure to comply with remedial orders. This makes early screening, complete documentation, and disciplined process governance critical for schedule and legal risk management.

What’s Required

Norway’s Impact Assessment Regulations implement requirements for environmental impact assessment (EIA) and strategic environmental assessment (SEA) for plans and projects that may have significant effects on the environment and society. Developers are responsible for preparing assessments and documentation, and authorities must follow defined procedures before decisions are made.

Key requirements include:

  • Screening and procedural steps for plans/initiatives that fall under the regulations, including preparation of impact assessment documentation where required.

  • The assessment process must satisfy evaluation needs under other relevant laws tied to the decision.

  • Developers must provide an EIA report and supporting material as part of permitting/planning workflows (project-dependent).

Important Deadlines

  • In force from 1 July 2017: the current Impact Assessment Regulations apply from this date.

  • Project-specific: deadlines are set within the relevant plan or permitting process, but compliance is required before final approvals are granted for covered initiatives.

Current Status

Fully in force, used across major infrastructure, energy, industrial, and planning decisions.

Penalties for Non-Compliance

  • The Regulations include a specific infringement penalty mechanism (Section 36) for certain procedural contraventions, including failure to follow required EIA procedures where a plan/initiative clearly falls under the rules, and failure to comply with orders to remedy.

Examples of Known Violations

  • Typical enforcement risk areas include initiating a covered project without completing the required EIA procedure, or failing to comply with authority orders to remedy procedural deficiencies, which can trigger infringement penalties under Section 36.
