Contractor Emission Calculator

Contractor CO2 emission calculator

Work carried out by contractors on your behalf has a carbon impact. This tool will allow you to calculate the carbon emissions associated with work carried out by office-based contractors (e.g. consultants). Using this with consultants will improve your carbon reporting, but also raise awareness of the need to manage emissions associated with contractors. Click here to find out how the tool works
