Commuting Footprint is the measure (in tonnes of carbon dioxide) of the impact your employees' travel to and from work has on your business's carbon footprint. As a so-called, scope 3 emission, your Commuting Footprint provides a more complete view of the impact your employees home-to-work travel has. It fits alongside measurement of your employees' Homework Footprint and reflects the blend over recent times to mix home and office-based working.
