A product's embodied carbon is the sum of its A1–A3 emissions per declared unit. The formula, the A1/A2/A3 split, pulling values from EPDs, the biogenic carbon distinction and a worked example for 1 m² of wall.
Read moreEPDs are shifting from marketing document to tender pre-qualification requirement. How specifications are written, and how to meet them.
Read moreA BIM model already contains a bill of quantities. The real obstacle to connecting it to LCA is not software but material mapping.
Read moreTrying to optimise every material wastes effort. The Pareto distribution, the weight of the structure and the five decisions that actually move the number.
Read moreLevel(s) is not a certificate but a common measurement language. Its six macro-objectives, indicator structure and relationship with existing schemes.
Read moreBREEAM assesses materials by building element rather than one by one. The logic of Mat 01 and what it means for a manufacturer.
Read moreLEED's materials credits tie points directly to product EPDs. The different weight of product-specific and industry-average EPDs, and embodied carbon reduction.
Read moreOptimising embodied and operational carbon separately gives the wrong answer. Cross-module trade-offs and the right place for Module D.
Read moreA building LCA is the work of assembling product EPDs. The bill of quantities, scenario definitions and setting the reference study period.
Read moreAs operational carbon falls, embodied carbon has become the dominant share. Which modules count, and which benchmarks apply?
