2024 Embodied Carbon Data for Timber Products

News Detail


Timber Development UK


All materials have an embodied carbon value, which reflects the emissions from all stages of production, use and end of life. This data is normally captured in the form of a verified EPD (Environmental Product Declaration). This Timber Knowledge Sheet provides weighted average A1-A4 embodied carbon data for a number of common timber products, and outlines the methodology used to calculate them.

The knowledge sheet uses A1-A3 embodied carbon data from verified EPDs, as well as information on UK production and imports from TDUK and Forest Research, to calculate a weighted average A1-A3 embodied carbon figure including and excluding biogenic carbon for the above products.

It also uses the data from the EPDs to determine a realistic scenario for the transport of these products to a nominal UK construction site to calculate a realistic A4 embodied carbon figure. The data has been verified in accordance with CEN/TR 15941:2010.
