Bidding has opened for slices of a £5M fund to create less-polluting buses.
English councils have until the end of October to apply for cash to retrofit buses with equipment to reduce nitrogen oxides emissions.
The Clean Bus Technology Fund 2015 will pay up to £500,000 to successful local authorities as the government works on reducing air pollution.
Transport minister Andrew Jones said: “The £5M Clean Bus Technology Fund will provide hundreds of cleaner buses to improve air quality in towns and cities across England and I urge local authorities to submit bids.
“The funding will also support the British industries helping deliver the technology. Today’s announcement continues the government’s commitment to improve air quality by upgrading existing vehicles on the road while also backing the low-emission solutions for the future.”
The European Court of Justice last year effectively ordered the government to produce plans to cut nitrogen dioxide levels in certain areas to below limits set out in the Air Quality Directive.
