Long-lived timber construction products deliver a net biogenic carbon storage benefit over the building service life.

Under review — the register is reading the literature and will publish a conclusion once directional evidence has been indexed.

In plain terms

The published record broadly agrees with this. Treat it as a working answer, not a settled one.

This sentence is generated from the same numbers shown below — consensus share, confidence band and the number of indexed studies. Open any section to see exactly how it was reached.

3/5
Where the literature disagreesNo direct contradictions in the indexed pool

No direct contradictions in the indexed pool. That is not the same as agreement — it can also mean too few directional studies have been published to disagree yet.

Life Cycle Assessment in Timber Construction and Existing Stock

Thomas Stark · 2025 · Timber Constructions in Existing Contexts · doi:10.11129/9783955536596-004

The title identifies life-cycle assessment in timber construction but provides no directional finding on biogenic carbon storage.

Neutral

Grade C · 0 citations

Peer-reviewed

Balancing the green carbon cycle — Biogenic carbon within life cycle assessment

Stefan Füchsl, Josef Huber, Magnus Fröhling et al. · 2025 · The International Journal of Life Cycle Assessment · doi:10.1007/s11367-025-02469-0

The paper evaluates general biogenic carbon accounting methodologies rather than storage performance of long-lived timber construction products.

Neutral

Grade B · 19 citations

Peer-reviewed

Biogenic carbon in buildings: a critical overview of LCA methods

Endrit Hoxha, Alexander Passer, Marcella Ruschi Mendes Saade et al. · 2020 · Buildings and Cities · doi:10.5334/bc.46

The study demonstrates methodological discrepancies in timber-building carbon accounting rather than a consistent net storage benefit.

Neutral

Grade A · 271 citations

4. Life-cycle assessment

Annette Hafner, Holger König · 2018 · Manual of Multistorey Timber Construction · doi:10.11129/9783955533953-005

The title indicates life-cycle assessment but provides no finding on net biogenic carbon storage.

Life-Cycle Assessment

2016 · Turning Point in Timber Construction · doi:10.1515/9783035608632-012

Neutral

Grade C · 0 citations

Stance classification is automated and reviewed against each record's own abstract; it is a reading of the literature, not a measurement. The Evidence Score is a rule-based function of indexed metadata under method WI-EV v1.0.0 and does not constitute proof of the statement.
