Summary

Norway’s Environmental Information Act ensures public access to environmental information held by public authorities and private undertakings. Companies can receive requests and must be prepared to respond; if they refuse or do not answer, the requester may appeal. A failure to respond within two months is treated as a refusal that can be appealed, and appeals must generally be filed within three weeks of receiving notice of refusal. The Act creates a strong transparency and reputational compliance driver, demanding reliable internal data and response workflows.

What’s Required

Norway’s Environmental Information Act gives the public rights to environmental information held by both public authorities and private undertakings, increasing transparency and creating response obligations for companies when requested.

Key requirements include:

  • Private undertakings must provide environmental information upon request, supporting transparency and public oversight.

  • If a request is refused or not answered, there are formal appeal mechanisms, including referral to the Appeals Board for Environmental Information.

  • If no answer is provided within a specified period, the Act treats this as a refusal that can be appealed.

Important Deadlines

  • Within 2 months: if no answer has been received within two months after the request was received by the undertaking, it is regarded as a refusal that may be appealed.

  • 3 weeks: time limit to appeal the date notification of refusal is received.

Current Status

Fully in force and widely referenced in environmental law guidance as a key transparency obligation affecting companies’ public disclosure readiness.

Penalties for Non-Compliance

  • The Act’s practical enforcement lever is the appeal mechanism (and public scrutiny). Non-compliance increases legal and reputational risk and can lead to formal adverse decisions through the appeal pathway.

Examples of Known Violations

  • Typical violation patterns include refusal to provide information without an adequate legal basis, or failure to respond (triggering the “deemed refusal” rule after two months), and resulting appeals.
