Real-Time LCA implements **Klimatdeklaration** — the mandatory climate declaration issued by **[Boverket](https://www.boverket.se/klimatdeklaration)** (the Swedish National Board of Housing, Building and Planning) under *[Lag (2021:787) om klimatdeklaration för byggnader](https://www.riksdagen.se/sv/dokument-och-lagar/dokument/svensk-forfattningssamling/lag-2021787-om-klimatdeklaration-for-byggnader_sfs-2021-787/)*, effective for new buildings since 1 January 2022.

## Klimatdeklaration

<LifecyclePhases included={['A1A3', 'A4', 'A5']} note="Blue = required modules under Klimatdeklaration. Current scope is the construction stage only (A1–A5)." />

* **Reference study period:** 50 years.
* **Indicator:** **GWP-IOBC** (GWP including biogenic carbon), reported in **kg CO₂-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)](/methodology-and-compliance/levels)) 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.
