KPI: Carbon dioxide emissions per passenger kilometre

The amount of Scope 1 carbon dioxide emissions in grams produced by our rail services per passenger km travelled. Scope 1 emissions are those arising from fuel consumption by our trains. This methodology is in line with Welsh Government reporting criteria for carbon emissions.

 

Overview

In Q2 2025/26, Carbon Dioxide Emissions per Passenger Kilometre decreased compared to Q2 2024/25. as a result of our transformation programme with the entry into service of new trains and increased usage of our services.

Q2 2024/25

81.2

Q2 2025/26

Well-being of Future Generations Act (WFGA) goals addressed:

2. A Resilient Wales

3. A Healthier Wales

4. A More Equal Wales

7. A Globally Responsible Wales

 

Forward look

We aim to publish a Carbon Management Plan and an Energy Strategy which we will use to manage our carbon emitting activities and increase energy efficiency. In 2026, we expect to see our carbon emissions from diesel decrease as our first hybrid trains and electric tram-trains are introduced onto the Core Valley Lines.
