A new report commissioned by Greener Journeys says that investing in greener bus technologies is the most cost-effective way of rapidly tackling urban air pollution. The report says that the latest clean bus technology is particularly effective at cutting pollution.
The report by Professor David Begg, Visiting Professor at Plymouth University and former chairman of the Government’s Commission for Integrated Transport, says that fitting air filters to, or replacing older diesel buses is up to 15 times more efficient than paying motorists to scrap diesel cars and that green bus technology is currently more effective at cutting pollution than the latest diesel car engines.
His report also warns that without Government support for clean bus technology, fares could rise by 40%
The report says that 'bus retrofitting' would cost the taxpayer just £12 per kilogram of nitrogen oxides saved. A bus scrappage scheme is almost as cost-effective at £16 per kilogram of NOx saved.
The report argues that if the Government is serious about tackling air quality in towns and cities across the UK, it must “put the bus at the centre” of its strategy.
It comments that the latest Euro VI diesel buses produce 95% fewer emissions than the previous models, and less emissions overall than a Euro 6 diesel car despite having the capacity to carry 15 times more passengers.
Claire Haigh, Chief Executive of Greener Journeys, said: “Air quality is among the most pressing concerns in towns and cities across the UK, and this vital report highlights the key role of buses as an integral part of the solution.
“Not only are the latest diesel buses cleaner than diesel cars, but taking cars off the road would also help reduce congestion, which causes tailpipe emissions to be increased by up to three or four times.
“Furthermore, putting buses at the centre of the air quality strategy would support UK manufacturing as at least 80% of urban buses sold in the UK are built in the UK.”
