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 Quarter 1 this year, the carbon intensity of our rolling stock has continued to decrease compared to Quarter 1 last year. This is largely due to the entry into service of new trains and increased use of our services.
Q1 2025/26 78.9 | Q1 2026/27 70.3 |
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 will publish a Carbon Management Plan which we will use to manage our carbon emitting activities and increase energy efficiency. In 2026/27, we expect to see our carbon emissions from diesel decrease further as hybrid trains and electric tram-trains are introduced onto the Core Valley Lines.
