ENVIRONMENTAL campaigners are calling on Sheffield bus bosses to go further in making their fleet more environmentally-friendly.
First, the city’s largest operator, last week announced plans to bring 40 new vehicles on to the streets by summer, and replace half of its fleet in the next five years.
The company is buying CityLite buses, which have lightweight bodies and Euro 5 diesel engines, which have low exhaust emissions.
But Neil Parry, of Sheffield East End Quality of Life Initiative, which campaigns against air pollution, said: “Road side testing work reported by Kings College London’s David Carslaw has shown that real life emissions of Euro 4 and 5 heavy vehicles have not led to reductions in emissions of nitrogen dioxide.
“Sheffield has an Air quality Action Plan that aims to bring air pollution in the form of nitrogen dioxide within EU limit values by 2015 to protect the health and wellbeing of Sheffield people.”
He questioned why First had not ordered buses with the very latest Euro 6 engines, or ones using compressed natural gas.
Mr Parry said: “Many European cities have adopted clean CNG engines for their buses - that’s where the future should be.”
