Our Carbon Footprint

At Greater Anglia we are working to quantify and reduce our carbon emissions from all of our business activities.

Greenhouse Gas Emissions are classified into 3 different groups called 'scopes'.

Scope 1 & Scope 2

  • Scope 1 emissions include diesel consumption (trains and buildings) and gas usage (buildings).
  • Scope 2 emissions include all electricity consumption (trains and buildings).

Our Carbon Emissions for 2021/22 financial year are shown in the table below:

Activity Total for 2021/22 (tCO2e)
Scope 1* Diesel use (trains) 24,791
Diesel use (depot buildings) 84
Natural gas (buildings) 2,163
Total: 27,038
Scope 2* Electricity use (trains) 50,783
Electricity use (buildings) 3,224
Total: 54,006
Total Scope 1 & Scope 2: 81,045

*This data has been externally verified by WSP, one of the world’s leading engineering consulting firms who provide consultancy services to the built and natural environment.

Overall Scope 1 and 2 emissions between 2020/21 and 21/22 have reduced by 11% or 10,464 tonnes. This reduction is in part thanks to the continued ‘greening’ of the National Grid which now uses more renewable sources to generate electricity, which in turn powers Greater Anglia’s electric trains, depots and stations.

Scope 3

We are working to quantify Scope 3 emissions which include more indirect emissions from the supply chain, emissions from business travel and emissions from leased assets and investments.

Examples include emissions from rail replacement bus services, leased vehicle usage and contractor emissions.

So far we have established:

Scope 3 activity Total for 2021/22 (tCO02e)
Business milleage 16.3
Taxis 72
Rail replacement bus services 624
Fuel cards 137.27
Consumption from tenants 563
Supply chain spend 167,561
Total Scope 3 so far: 167,561

We are working to increase accuracy of reporting of scope 3 and will work with our supply chain to quantify and then reduce scope 3 emissions.

Progress against Environmental Targets – 21/22

Target 21/22 Performance
To reduce non-traction energy by 2.5% per year 7% reduction since 20/21
To meet carbon trajectory to deliver a 40% reduction in kgCO2e/vehice km by 2025/26 38.8% reduction in emissions achieved so far
To recyce or reuse 60% of waste 57% achieved
To ensure zero waste from stations goes to landfill 100% achieved
To baseline water usage consumption differentiate consumption from stations and depots

Overall consumption 21/22 111,574m3

Stations 64,712m3

Depots 46,861m3
