Carbon emissions

Significant amounts of energy are required to pump water and wastewater around our region and treat it to high standards for our customers. We monitor our emissions and are taking steps to become carbon neutral by 2030.

We publish our annual emissions figures here (last updated March 2021).


Our emissions performance

The bar chart below shows our overall yearly emissions (financial year, April–March) across all of our offices and operational sites in Kent, Sussex, Hampshire and the Isle of Wight.

The methodology for reporting meets Defra guidance and is calculated using the Water Industry Carbon Accounting Workbook developed by UKWIR.

As the population in our region increases, demand for our services goes up. However, despite having more customers to serve, we’ve maintained a downward trend in our emissions. The chart below shows our annual emissions per customer served for the last six financial years:

With a rising population in the South East and increased treatment standards, reducing emissions is challenging. Despite these factors, our emissions have decreased year-on-year.

This has primarily been possible due to the decarbonisation of the national grid, which has a reduced reliance on fossil fuels. In addition, we have invested in renewable energy to proactively reduce our emissions including the installation of solar panels to help power our treatment works.


Net Zero Commitment

We have committed to support industry body Water UK’s Net Zero commitment – to become carbon neutral by 2030. To achieve this, we'll reduce and mitigate our emissions and work with our partners to find sustainable solutions.
