Suriya Edwards Managing Associate at Foot Anstey<\/a> and Gena Ritchie Trainee Solicitor, talk about adopting Modern Methods of Construction (MMC) to tackle embodied carbon<\/h2>\n

So far, we have focused very much on emissions released during the operational life. However, the concept of “embodied carbon” has always existed, invisible previously, but is gaining momentum.<\/p>\n

A couple of years ago the World Green Building Council (GBC) brought out an interesting report “Bringing embodied carbon upfront”. It lifted that invisibility cloak and asked us not to ignore the emissions released by the manufacturing, transportation, construction\u00a0and end of life phases of buildings. These emissions are known as “embodied carbon”, and according to the World GBC contribute to 11% of all global carbon emissions.<\/a><\/p>\n

A key source of embodied carbon the report identifies are construction elements and materials. Due to their carbon intensive load bearing, structural materials such as concrete and steel and building elements, such as foundations, frames and other forms of superstructure represent the biggest contribution to embodied carbon. This, therefore, requires further attention.<\/p>\n

That attention may be lacking in certain areas, for example, there has been some criticism that the UK Government’s Heat and Building Strategy<\/a> includes details on reducing operational carbon but lacks focus on embodied carbon. That said, it is gaining momentum in other areas and here are some solutions.<\/p>\n

Product Innovation<\/h3>\n

It was recently reported in the Economist that if the cement industry were a country it would be the third largest emitter in the world, after China and America. This is mind-boggling to consider. However, there are solutions such as the innovations and testing currently underway to produce green cement as the report goes on to say. For a great example, see Heidelberg’s carbon capture and storage project.<\/p>\n

Modern Methods of Construction (MMC)<\/h3>\n

Cross-laminated, engineered timber (a sub-set within MMC) is both a sustainable source and is now being used more and more in construction, including in high rises. As well as reducing the energy used during the construction process MMC<\/a> can considerably improve the energy efficiency of buildings once they have been built. Precise MMC factory processes also allow for more effective waste management, as well as enable materials to be ordered and specified with better accuracy. This means that embracing MMC can reduce energy bills and building costs whilst at the same time driving UK forwards in the race to achieving net zero.<\/a><\/p>\n

Finally, the contract:<\/h3>\n

The Chancery Lane Project’s (TCLP) and its freely available net zero clauses provide clients a great starting point to tackle embodied carbon, and to consider using sustainable materials:<\/p>\n
