Embodied carbon calculations

Earlier this year, we declared a climate and biodiversity emergency. Since then, we have focussed on facing this emergency and acting on it. Our strategy is simple; measure the scale of our emissions across the board, decipher the impact areas, and reduce them. The aim is to be truly transparent with our figures and track progress moving forward.

We have calculated the embodied carbon across a range of projects in order to understand our baseline performance alongside industry standards. Using the IStructE carbon calculator tool and data published by them and other peer firms (2020) to understand typical carbon values. From this we have gained learnings which we can continue to implement in future projects. The majority of our new build projects performed in line with industry averages but require improvement to reach future targets. This is to be expected and underlines the fact that building conservation is paramount to minimise environmental impact. Carbon calculations are still in their infancy and do incur inaccuracies, but enable improved decision making. There are certainties such as: less virgin material use means less carbon. We are therefore proud to be experts in refurbishment and are working on ensuring lean design solutions.

Having understood our baseline performance, our engineers have now begun rolling out carbon calculations on their projects. This month, we started offering quantified low carbon alternative design solutions. This momentum is building and we will enable all clients to have access to quantified information on effective carbon reduction by 2022.
