Note
From 1 October 2026, the publisher of the Inventory of Carbon & Energy (ICE) database, Circular Ecology, will no longer provide free access to its carbon factor dataset outside of educational use. As a result, users of the Institution’s
How to calculate embodied carbon guide and Structural Carbon Tool should review their approach to sourcing carbon data and ensure the figures used remain appropriate and up to date. Circular Ecology has launched a commercial successor, IC+, while alternative sources such as environmental product declarations (EPDs) and other carbon databases remain available. The Institution’s Climate Committee is currently reviewing the implications of these changes and the impact on future updates to the IStructE’s recommended embodied carbon factors.
