WHOLE LIFE CARBON
We work closely with clients across all sectors to set realistic targets and identify achievable steps and measures towards decarbonization. Whether planning and advising on carbon reduction strategies, delivering net zero program management, or through sustainable design and stakeholder engagement, our integrated solutions embrace the principles of circular construction to focus on where, when and how places are created, offering speed and certainty of outcome every step of the way.
As quantity surveyors, we are responsible for the quantification of the design and specification of buildings, bridges and other infrastructure projects. These are often high in embodied carbon — carbon dioxide, or carbon dioxide equivalent (CO2e), is released into the atmosphere during manufacture and transportation. This in turn causes climate change.
CALCULATING EMBODIED CARBON
Embodied carbon figures account for emissions at each stage of a material’s journey to the finished outcome — including extraction, processing, manufacture and assembly — and represent the total impact of the structure on global warming. We use data from the carbon accounting tool 𝗢𝗻𝗲 𝗖𝗹𝗶𝗰𝗸 𝗟𝗖𝗔 for our calculations, which is a recognisable benchmarking tool to provide a good basis for comparing the relative impact of different design proposals and options.
To calculate the embodied carbon we also need to know the quantities of each material used in each frame. All our projects are modelled in 3D and elements are categorised according to system type and material, such as concrete foundations. We extract quantity data for each structural system and multiply with the corresponding embodied carbon figures from the One Click database to produce a total embodied carbon figure for that project.
