Emissions Avoidance with Carbon Twins

Real-time whole life carbon (WLC) analysis from concept to demolition

of carbon emissions from the built environment


from operational carbon


from embodied carbon


predicted embodied carbon share by 2050 (BAU)

We don't have much time...

We only have until 2030 to make a lasting impact on the future of our planet. With the built environment being a significant contributor to global carbon emissions, buildings are a key lever to combatting climate change!


Preoptima revolutionises the way you approach sustainable building design and carbon analysis.


As a Carbon Twin, Preoptima mirrors your every design choice, instantly evaluating the whole life carbon (WLC) impact of your decisions. Both our Web App and API provide unprecedented access to real-time carbon impact data, an accurate bill of quantities, and associated material and structural impact information.

By harnessing the power of geolocation and real-time analysis, Preoptima allows you to visualise and understand the WLC footprint of your projects from the earliest stages, helping you avoid embodied carbon and reduce emissions from the outset. Your trusted Carbon Twin makes achieving Net Zero easy.
