Sustainability & Wellbeing

The most sustainable way to create a new workspace is to use what’s already there.

Retaining and refurbishing the existing building is equivalent to at least 13,500 tCO2e* saved vs building a new zero emissions building. That’s the same as:

The annual carbon associated with 1,040 UK citizens

Building 170 new homes

27 hectares of deforestation

Or 3 flights in a space shuttle

Mainframe will be aiming to achieve the
following minimum accreditations

*Please note that these are high-level calculations based on estimates and comparable case studies and should not be relied upon for statutory reporting or financial decision-making.
