Date published: 21 March 2023

You asked

Hello, I am looking for carbon footprint information to assist my organization in calculating our carbon footprint for 2021. Could you let me know please the average carbon emissions from London Underground per passenger per journey? Not per kilometer, but per average tube journey please. If you do not have information on "average journey", then could you let me know please the length of an "average journey" in km? I was not able to find information at this level in the document: https://tfl.gov.uk/cdn/static/cms/documents/safety-health-and-environment-annual-report-2021-22.pdf If you have this information, I would be very grateful. Many thanks and best wishes.
