It’s widely accepted that climate change is a serious issue and a major challenge to society. Our customers have told us that they want a service that is resilient to challenges. This includes current and future challenges including climate change. It's hard to predict the full extent and precise timing of its impacts. Planning for issues can make this extremely challenging.
We have considered climate-related risks, impacts, and opportunities for our services. We also considered population growth, environmental regulation, financeability and affordability to customers. You can find out more about what we're doing to tackle climate change in our reports:
We have developed a plan to reduce the impact of climate change as part of our business planning. Key issues were found to be still broadly related to either too much, too little or the wrong sort of water. This challenge is reflected in performance commitments as agreed by Ofwat.

Reducing our greenhouse gas emissions (GHG)
We believe it's important to set our sights high to help keep global warming below 1.5°C. We're working to reduce our emissions to net Zero.
For over 30 years, we’ve been on a journey to manage and reduce our carbon emissions. Our net market based emissions were 350.4ktCO2e in 2023/2024. Emission reduction activities include:
- Self-generating renewably 21.1% of the electricity we used
- Harnessing wind, solar, and poo power
- Managing our greenhouse gas emissions
We’ve been producing sustainable energy at Mogden sewage treatment works since 1930s. In 2023, we completed our latest biomethane plant at Mogden. It will export biomethane into the gas grid to substitute fossil fuel Natural Gas. This is the equivalent to providing the heating and cooking requirements of over 4,000 homes.
