A campus footprint is the buildings, and how everyone gets there
A campus runs like a small city, but the energy on its meters is rarely the biggest line. For most institutions the larger footprint is the thousands of students and staff commuting in, and everything the campus procures. The analyst accounts for the buildings, the travel and the supply chain together.
You stay the reviewer
Campus data in, a defensible number out
The inputs span the whole campus: energy invoices across many buildings, fleet fuel, and the travel survey behind the commuting estimate. The analyst matches each to the right factor and produces a footprint you can defend to an assurer or a ranking body.

How it works
Drop in energy invoices, fleet fuel, commuting surveys and procurement spend, the analyst calculates each scope with matched factors, and you report per campus, per faculty or consolidated across the institution.

Buildings and fleet
Lecture theatres, labs, residences and a grounds fleet are the metered core. CO2 Lab reads electricity, gas and fuel per building and vehicle, applies the current NGA factors, and reports location-based and market-based electricity side by side.

Scope 3 · Category 7
Commuting
Thousands of people travelling to campus is often larger than the buildings themselves. CO2 Lab takes mode split off your travel surveys, applies the right factors, and labels the line as modelled, so a dominant but estimated source is disclosed honestly rather than left out.
Scope 3 · Category 1
Procurement
Research equipment, IT, construction and services add up across a large institution. CO2 Lab starts from procurement spend with spend-based factors, swaps in supplier data as it arrives, and labels every line so you can see what is estimated and what is real.
