// About Sterling

What drives us

Did you know that approximately 40% of annual global Greenhouse Gas emissions is generated by building and operating assets, while 28% of this is embodied carbon which can only be tracked and influenced at resource level not in high level cost plans.  Professionals within the built environment sector are increasingly expected to recognise, replace, reduce or remove carbon rich activities/resources to meet Net Zero Carbon ambitions.  We know the industry needs a reliable tool to help manage this – easily.

It is time to ‘Prove and Improve’ your carbon footprint with Sterling.
