*CO2e.(carbon dioxide equivalent) includes all four greenhouse gases, although our emissions are primarily CO2, including:

direct emissions (scope 1) from on-site use of energy (gas),
indirect emissions (scope 2) from purchased energy (electricity),
and emissions resulting from business travel and waste (scope 3).

Our scope 3 calculation does not currently include visitor travel and other indirect emissions e.g. from suppliers.
