constructionlca is Jane Anderson. I was the co-author of BRE’s Green Guide to Specification, and I’m an expert in Life Cycle Assessment (LCA), Environmental Product Declarations (EPD) and sustainability for the construction materials sector. I’m the UK expert on CEN/TC350/WG3, which developed EN 15804:2013, the European Standard for EPD for construction products, and ISO/TC59/SC17/WG3 which developed ISO 21930:2017. I run my own consultancy, ConstructionLCA Ltd specialising in EPD Verification, PCR development, Peer Review of LCA studies and advice around LCA and EPD.
