Transport Secretary Douglas Alexander called in at the Oxford Bus Company headquarters yesterday to see its environmentally-friendly buses.

The Watlington Road-based company recently became the first operator in Britain to introduce EuroV buses and coaches with the highest environmental standards. It has invested more than £25m over the last few years in the latest, most environmentally-friendly buses, and has fitted particulate traps to all vehicles.

Mr Alexander said: "Reducing air pollution is a priority for Government and industry alike.

"By operating vehicles that meet the highest air quality standards, the Oxford Bus Company is making a contribution to tackling transport's impact on the air we breathe.

"I'm pleased to see the company takes its environmental responsibilities so seriously."
