Social Responsibility and Sustainability


Use the dedicated business travel report to explore the University's travel data.


We have developed a world-first interactive business travel report that can help everyone to understand travel emissions related to their school or department and those of the University as a whole. This report collates data on journeys from our main travel suppliers as well as the University's internal expenses system, and we use the most recent conversion factors provided by the the UK Governments Department for Environment, Food and Rural Affairs (DEFRA) to accurately calculate the associated carbon emissions from a journeys distance.

Included within scope are any journeys paid for by the University - whether by staff, student, visitor, or invited guests.

When looking at the carbon emissions from a journey, we account for a number of factors including:

- Mode of transport. Including: Air, rail, hire cars, mileage - by car and motorbike, taxis, ferries, coach and busses

- Number of passengers. Should more than one traveller be linked to the journey in question

- One-way or return journey. This is dependent on the supplier and mode of transport. For example, all journeys from our main travel management company (Key Travel) are assumed to be single, while all air and rail journeys gathered via the University’s internal expenses system are assumed to be return (unless stated otherwise)

Class of travel. For air journeys only. Including: economy, premium economy, business class, or first class

- Flight type. For air journeys only. Including: domestic, short haul, long haul, or international flights

- Radiative forcing. For air journeys only. Radiative Forcing is the additional warming effect due to the release of emissions high in the atmosphere


SRS have released a methodology statement which outlines how the Business Travel Report collates and processes journeys.


The full, interactive report can be found on the dedicated Business Travel Report site. This report is updated annually between September and December.
