We recognise that the benefits of purchasing a low carbon bus will be different for each operator and will depend on the way in which the bus in service is used. So, Department for Transport economists have produced a transparent, user-friendly toolkit to be used by bus operators and local authorities to calculate the likely benefits on investing in a low carbon emission bus (LCEB). Your assessment should always compare the LCEB to an equivalent diesel bus.
This toolkit allows you flexibility in changing the input assumptions to those most relevant to you. You will be able to assess the financial implications of purchasing a LCEB, based on the fuel savings on offer (as advised by LCEB manufacturers or experienced in trials).
This spreadsheet tool is intended to provide indicative estimates only and DfT does not vouch for the accuracy of such estimates. Please note that the Department for Transport does not accept any liability for any decisions that may be taken on the basis of such estimates.
This toolkit will be routinely updated and refined. Details of any updates or changes that are made will be outlined in the ‘Intro’ worksheet of the toolkit. We therefore encourage you to visit this website regularly and download the toolkit to ensure you are using the latest version.
