- Diesel and electricity consumption increased in the year April 2021 to March 2022. These increases led to a 2% rise in the total estimated CO2e emissions for passenger and freight (to 2,282 kilotonnes). This is the second lowest level since the comparable time series started in April 2011.
- There are new normalised electric and diesel metrics which allow for comparisons between the two traction types. Normalised passenger emissions were 358g CO2e per electric vehicle km, compared to 1400g CO2e per diesel vehicle km.
- For both passenger and freight trains, electricity emissions reduced despite increases in electricity consumption. This was due to changes in electricity generation towards more renewable sources.
