Perega, one of the UK's leading structural and civil engineering consultancies, has announced the launch of its innovative CO2 accounting tool: The Carbon Calculator.

Affirming its commitment to sustainable construction, this evolutionary platform empowers Perega's clients to assess the whole carbon footprint of their projects, from inception to completion. Importantly, it enables them to make greener material choices to faster, and better, achieve a more sustainable built environment.

The calculator has been developed by the firm's dedicated, in-house Net Zero Carbon Group and uses a sophisticated algorithmic framework, analysing material emissions data to achieve lower-carbon outcomes.


Harnessing the power of the latest digital technology, the calculator seamlessly integrates within the Revit model, offering a comprehensive carbon impact assessment.

Key features of the Perega Carbon Calculator include:

• Real-time comparison between different schemes, to identify lower carbon options

• Identification of high embodied carbon elements, and assessment of potential changes for improvement

• User-friendly dashboard, presenting concise and informative carbon impact assessments based on specified material types and volumes

• Swift advisory services from in-house technical experts on carbon reduction strategies, aligning with design brief requirements and Net Zero 2050 targets

Commenting on the impact and efficacy of the tool, Perega's Digital Engineering Lead, James Washbourne, said: "With the built environment responsible for 40% of global emissions, the imperative for lower-emission practices has shifted from optional to essential. Our Carbon Calculator makes another step towards achieving more sustainable projects. Moving away from manually crunching static spreadsheets to a predominantly automated process means better pinpointing of carbon hotspots and empowering our clients to make correct material substitutions during the design phase, without compromising on quality.

"Ensuring user-friendliness was crucial, our clients are incredibly busy and need to be able to read and understand the data quickly to make informed decisions. As such, we developed the calculator to deliver clear and simple comparisons for effective decision-making."
