A clean diesel campaign is hoping to reduce vehicle emissions in the US state of Connecticut.

The Environmental Protection Agency (EPA) scheme has made funding available to help reduce harmful emissions from school buses.

It is hoped that installing diesel particulate matter filters on school buses as well as fuelling them with ultra-low sulphur diesel will improve the local environment and contribute to wider efforts to reduce emissions.

"[The] EPA's programme aimed at reducing diesel emissions from school buses plays a critical role in improving air quality in the state of Connecticut," said the state's environment commissioner, Gina McCarthy.

The EPA said this week that it had made $1.4 million available in new funds for clean diesel programmes in eight north-eastern states.

This comes as vehicle manufacturers come under increasing pressure from lawmakers to limit their diesel emissions.

Last year, President Bush accepted that the US would have to explore cleaner, alternative fuels.
