Trentbarton is to spend £5m in 2018 on 30 new Euro 6 buses for its i4 and indigo routes. They will help Derby as the city prepares to introduce a Clean Air Zone in 2020.
It is inviting manufacturers to bid for the new order, which will take the number of Euro 6 vehicles in the Trentbarton fleet to 108.
MD Jeff Counsell says: “It’s a sign of our commitment that we are again investing a considerable amount of money into cleaner buses.
“Congestion and pollution go hand in hand and an effective and attractive bus network should be seen as a crucial part of the solution to tackling pollution.”
