New Clean Air South report highlights role of zero-emission buses in improving air quality

The report, led by the University of Southampton alongside local authorities, businesses and health organisations, brings together examples of initiatives designed to tackle air pollution and improve public health across the region.

Among the case studies featured in Clean Air South: Sharing solutions and good practice, which showcases practical initiatives helping tackle air pollution across the region, is Portsmouth’s electric bus programme. Delivered through active partnership between First Bus, Portsmouth City Council and Hampshire County Council, the programme has seen the city’s 62 zero tailpipe emission buses complete nearly four million journeys, helping reduce emissions and support improved air quality across Portsmouth.

The report also highlights the importance of collaboration between local authorities, industry, healthcare organisations and communities in addressing air quality challenges.

First Bus is continuing to invest in zero-emission vehicles and depot electrification as part of its commitment to supporting cleaner, healthier communities. The business operates around 1,500 zero-emission buses across the UK, with more than a quarter of its fleet now zero-emission, and remains committed to operating a fully zero-emission fleet by 2035.

Isabel McAllister, Chief Sustainability and Compliance Officer at First Bus, said:

“We welcome the publication of this report and the focus it places on improving air quality across the South. Public transport plays a vital role in reducing emissions and congestion, particularly in urban areas such as Portsmouth and Southampton where transport contributes significantly to poor air quality.

“Working in partnership with local authorities, including Portsmouth City Council through initiatives such as the city’s electric bus programme, we are helping support wider decarbonisation ambitions and improve local air quality.

“The report rightly highlights the importance of collaboration between industry, local government and other stakeholders. Addressing air quality challenges requires long-term partnership working, investment and practical solutions that make sustainable travel more accessible and attractive for customers.”

Cllr Kimberly Barrett, Cabinet Member for Climate Change and Greening the City at Portsmouth City Council, said:

“Portsmouth’s inclusion in the Clean Air South report highlights the real impact of the city’s shift to cleaner transport. First’s electric bus fleet is already cutting emissions on some of our busiest routes, improving air quality for the communities who feel pollution most. Electrification is one of several steps we’re taking to support healthier, low‑emission travel across Portsmouth.”

The Clean Air South report was produced in association with the University of Southampton’s Sustainability and Resilience Institute and Wessex Health Partners and highlights a range of regional initiatives focused on reducing emissions and improving public health outcomes.
