Climate change strategy

Our climate commitment

In July 2021, we published our climate change strategy with ambitious targets to decarbonise our operation and adapt our business to the impacts of climate change. The strategy also focuses on our greatest contribution to reducing carbon emissions in the regions we operate: enabling people to shift from private cars to public transport.

The Group’s overarching target is to become a net zero carbon business by 2045. As milestones on the way to this target, Go-Ahead plans to achieve a decarbonised bus fleet by 2035 and to eliminate all remaining diesel trains from its networks by 2035. This will enable us to meet our validated Science Based Target of a 75% reduction in our scope 1 & 2 emissions by 2035.

David Brown, Group Chief Executive of Go-Ahead Group

Public transport is fundamental in tackling climate change and at Go-Ahead, sustainability is at the core of every major decision we take.

We are on a journey towards decarbonising our business by investing in zero-emission buses and trains. Equally importantly, we want our buses and trains to be the mode of transport of choice for local journeys, encouraging people out of their cars.

Part of the climate solution

We want public messaging which clearly states:

"Walk and cycle if you can, use buses and trains. Only take the car if you need to."

  • A fully loaded double decker bus can take 75 cars off the road. A train can replace even more.
  • Buses only account for 3% of all roadside emissions. We need more people to leave their cars at home and use public transport.
  • Prioritising bus and investing in rail are climate change solutions
