Emma Hardy, Air Quality Minister, said the government was “determined to protect communities from the harm that breathing in dirty air brings”.
“This vital investment is helping to transform the bus networks for the cities of Bradford and Sheffield, providing residents with greener alternatives that will boost the local economy and deliver cleaner air,” she said.
The number of buses the money will fund has not yet been announced.
Hunt said the grant was “great news for Sheffield”.
“It will mean we can get more zero emission electric buses on our streets, replacing older, polluting, diesel buses,” he said.
Meanwhile, Hinchcliffe, said the buses would “accelerate” improvements in air quality.
“The clean air zone has improved our air quality hugely and resulted in people needing to visit GPs less with respiratory problems,” she said.
