The Institution of Structural Engineers (IStructE), along with authors from Arup and WSP, have introduced a practical “how-to” guide for use on building projects looking to align with the UKNZCBS – either with the aspiration to achieve full verification, or simply as a model of best-practice assessment and reporting.
It provides diagrams, useful explanations, tips and tricks, and highlights important considerations. A step-by-step process for selecting embodied carbon limits is set out, and guidance is provided for conducting lifecycle embodied carbon assessment and best-practice carbon management during design and construction. Two worked examples are also presented, showing how lifecycle embodied carbon assessment is used to check against upfront embodied carbon limits.
NOTE: The guide covers the Pilot rev2 version of the Standard, and should therefore be treated as a Pilot Guide. It is the intention of the Institution to release an updated guide in Q1 2026, based on Version 1 of the Standard when it is released. Please send any feedback on the Pilot Guide to [email protected] so the authors can consider this ahead of updating and launching Version 1.
