Carbon and air quality resource centre

Welcome to our resource centre. Here we share details of what we are doing to help fight climate change and improve air quality. We've also compiled a list of useful documents and links with the aim of giving you access to information from a wide range of resources in addition to our own resources.

As your local bus company, we recognise that we have a responsibility to reduce our fuel use and emissions to help improve the lives of the people and communities we serve. We are committed to aggressively decarbonising our fleet and continuing to explore cleaner, renewable alternatives to fossil fuels, which cause carbon dioxide levels to rocket, trapping heat from the sun and warming the planet.

Whilst only 4% of UK roadside emissions come from buses, we still want to make every change we can to help make a difference. Over the last four years our miles per gallon (MPG) has improved by 7.5% with fuel consumption dropping by 1 million litres. Site energy has improved with electricity by 28% and gas by 6%. Co2 emissions combined have improved by 16% at 29,000 tonnes and we want to make this even better. We also continue to invest extensively in a low carbon fleet:

  • 54 E400ER hybrid electric buses with geo-fenced zero emission electric only operation through Brighton’s Low Emission Zone delivering 3,000,000 passenger journeys and 244,000 miles of zero emission bus travel every year. 
  • EuroVI technology augmented by Microhybrid advances: 82 buses in Brighton since 2015
  • Upgrade of SCRT equipment to a further 90 buses to further aid air quality improvement
  • 31 Microhybrid EuroVI buses since 2015 for Metrobus.
  • We also plan to introduce Hydrogen Fuel Cell Buses on our Fastway routes in Autumn/Winter 2021, with further routes to follow then into Brighton.

Here you’ll find links to useful reports and websites regarding air quality, climate change and carbon.
