This is part of Bluestar's wider commitment to improving air quality in the area.

They have invested in a fleet of greener vehicles.

Ms Honer added: "Bus travel has changed beyond recognition over recent years and those who haven’t travelled with us recently will be amazed at the enhancements we’ve made."

Discounted tickets can be purchased via the Bluestar app using the code EARTH25.
