Timber Development UK (TDUK) has published the 2026 Embodied Carbon data for Timber Products. This provides the average carbon data for the 11 major timber product categories. A fully updated version of the 2025 information, the data allows designers to weigh up the carbon impacts of their material choices. The figures clearly show how selecting a particular timber product will affect the embodied carbon of a design, with many UK sourced timber products having a lower A1-A4 embodied carbon impact than their imported counterparts. This independently verified information calculates weighted average upfront A1-A4 embodied carbon data for all of the most common timber products used in the UK – both including and excluding biogenic carbon, and also includes a stored biogenic carbon figure for the product. The new publication now also includes end-of-life C1-C4 embodied carbon impacts.
