Carbon emissions 2020/21 update
Carbon emissions 2020/21
May 2022 update
Initial assessment of our 2020/21 carbon emissions estimated a total footprint of 603,070 tCO2e. During analysis of data collected for the 2021/22 report, discrepancies were found within our supply chain emissions. Further analysis discovered double-counting within the underlying spend data. These errors have now been fixed and a revised report for our 2020/21 emissions has been completed.
The revised report estimates our total footprint for 2020/21 to be 242,756 tCO2e. The biggest change in our report came from our supply chain emissions, originally counted at 521,164 tCO2e. We’ve removed any duplicated underlying spend data, resulting in a new figure of 160,850 tCO2e.
This updated report has been produced to account for the corrected supply chain data and adjusted total emissions for 2020/21.
Our carbon footprint 2020/21
Scope 1
Direct emissions resulting from operations and activities that TfW owns or controls.
Scope 2
Indirect emissions from grid-supplied energy.
Scope 3
Indirect emissions resulting from activities related to TfW operations, but not within our direct control.
Scope 1 - 27%
Scope 2 - 1%
Scope 3 - 72%
How we’re reducing our emissions
We’re committed to reducing emissions from our supply chain where possible.
We’ll perform ongoing analysis of our supply chain emissions to establish an accurate representation of the carbon footprint from the goods and services we buy, identifying opportunities for emission reductions to support our 2030 decarbonisation targets.
Our highest emitting activity
Supply chain 160,850 tCO2e
This is due to our extensive transformation programme.
Our supply chain is essential help us create:
- Infrastructure upgrades and maintenance
- Metro transformation
- New rolling stock
- New depots and station buildings
