Electric buses could help cities save millions for society and the environment.

That’s the finding of research by car manufacturer Volvo and KPMG which analysed a city with around 500,000 inhabitants and 400 buses.

It stated e-buses would save cities up to SEK100 million (£7.8m) per year.

They could also reduce 33,000 tonnes of carbon emissions annually.

Niklas Gustafsson, Head of Sustainability at the Volvo Group said: “Standard investment appraisals do not take into account all of the costs that impact society and the environment. Therefore, to quantify all of the aspects, we have now calculated the monetary value of an electric bus line. The results show that irrespective of the number of parameters taken into consideration, electric buses comprise the leading public transport solution.”
