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 2025/26, the carbon intensity of our rolling stock decreased compared to 2024/25. This is largely due to our transformation programme with the entry into service of new trains and increased use of our services. We will use the newly published Carbon Management Plan and an Energy Strategy to manage our carbon emitting activities and increase energy efficiency.
2024/25 80.5 | 2025/26 71.2 | Q4 2025/26 75.4 |
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
In 2026/27, we expect to see our carbon emissions from diesel decrease as our hybrid trains and electric tram-trains are introduced onto the Core Valley Lines.
