By managing our businesses in a responsible and sustainable way, we help create a thriving economy whilst limiting our impact on the environment.

Our activities have environmental impacts - both positive and negative. Minimising our impact and taking steps to protect and enhance our environment, is fundamental to our strategy.  

Improving on our environmental impact

Bus and rail travel are a force for good and we take our role seriously as being part of the solution in tackling climate change and poor air quality. We are part of the solution and continually seek innovative ways to maximise the benefits we bring and minimise our adverse impacts on the environment. Trains and buses are two of the greenest travel choices people can make; one bus can carry up to 75 people and a single train can carry over 1,000, collectively taking thousands of cars off the road.

In July 2021, we launched our Climate Change Strategy setting out the how we will continue to adapt to the effects of climate change. This includes decarbonising our transport fleet, reducing the negative impact of air quality from our operations, cutting our water usage and reducing waste. We have set a Science Based Target to become a net zero carbon business by 2045, with ambitious milestones along the way. 

Governance is provided through the Climate Change Task Force, a multi-functional, multi-business team of people selected from across operating companies and head office, charged with formulating this plan and enabling the subsequent programme of climate-related projects to be delivered successfully.
