Real-Time LCA implements Klimatdeklaration — the mandatory climate declaration issued by Boverket (the Swedish National Board of Housing, Building and Planning) under Lag (2021:787) om klimatdeklaration för byggnader, effective for new buildings since 1 January 2022.

​
Klimatdeklaration

  • Reference study period: 50 years.
  • Indicator: GWP-IOBC (GWP including biogenic carbon), reported in kg COâ‚‚-eq per m² — note: no /year denominator for this calculation type, unlike most other regulatory calculation types in Real-Time LCA.
  • Threshold: none defined at this time.
The current Klimatdeklaration scope is limited to the construction stage. Boverket has announced phased expansion in scope — additional modules and a limit value are expected in subsequent revisions — and Real-Time LCA will update this page when the expanded ruleset is implemented as a separate calculation type.

​
Custom and Level(s)

Real-Time LCA additionally exposes Custom (user-defined scope, GWP-IOBC in kg CO₂-eq / m²) and Level(s) (full EN 15978 module set with standard GWP — see Level(s)) for Swedish projects. Projects requiring documentation beyond the current Klimatdeklaration scope (whole life-cycle, including B and C modules) should use Level(s) in parallel.

​
Reference Service Life

For the Klimatdeklaration calculation type, the reference service life only enters into B4 — which is not in current Klimatdeklaration scope — so RSL handling is relevant when running parallel calculations (Level(s) or Custom) rather than for the regulatory submission itself.

​
Limitations

  • The current Klimatdeklaration covers only the construction stage (A1–A5). Use of the building (B), end of life (C), and module D are not part of the submission.
  • The indicator naming GWP-IOBC differs from standard EN 15804+A2 GWP. The Klimatdeklaration value is not directly comparable to GWP values produced by Level(s) or BR18-style calculations.
  • The reporting unit is per m² without a /year denominator. When comparing Swedish results to other countries’ per-m²/year figures, divide the Klimatdeklaration value by the reference study period (50 years) to obtain a roughly equivalent per-m²/year intensity — keeping in mind that the module scope is narrower.
