Request ID: FOI-1793-2223 Date published: 27 October 2022
You asked
Hi there,
I am trying to calculate my carbon footprint from taking public transport, specifically with London Underground and was hoping to find out what was the emission per distance in gCO2e per passenger km.
The only information I found was on page 59 of the 2018/2019 annual Health Safety and Environment report, but I was hoping for an updated figure for 2021/2022 as I imagine it would be rather different after three years.
Any help on the matter would be appreciated. Thanks!
Kind regards,
