Reporting Requirements and Process
Environmental Reporting (GHG Accounting)
Under § 17-1, when constructing or substantially renovating residential blocks and commercial buildings, responsible parties must prepare a greenhouse gas account (klimagassregnskap) based on NS 3720:2018 methodology. The account must cover specified lifecycle modules (A1–A4, B2, B4) and include site waste emissions. Third-party verified, life-cycle-based documentation such as EPDs is recommended for material emission values; where EPDs are unavailable, generic data may be used with a 25 % safety margin applied.
Documentation and Submission
The greenhouse gas account must accompany final construction documentation at project completion (not at permit submission).
Documentation is used by authorities and for internal quality control.
Tools and databases (including EPD data or national inventory sources) support calculating and reporting results.
Penalties for Noncompliance
TEK17 itself is enforced through the building permit and inspection regime administered by municipal authorities and the Norwegian Building Authority (Direktoratet for byggkvalitet). Failure to produce required documentation, including greenhouse gas accounting where applicable, may lead to permit delays, corrective orders, or refusal of final approval under the Planning and Building Act enforcement framework.
Current Status
The greenhouse gas accounting requirement in TEK17 (§ 17-1) has been in effect since 1 July 2022 with a one-year transition period; projects with permits submitted after this period must comply. Guidance documents and practical support (e.g., Veileder for utarbeidelse av klimagassregnskap) are published to help industry actors fulfil the requirement.
