Save water to cut carbon

Find out how saving water can improve your carbon footprint – and discover how you can track and improve your water-related emissions with Giki's interactive, online guide.

You may wonder what your water habits have to do with carbon emissions. The answer is twofold: getting treated water to your home uses lots of energy – and how you use it next has an impact too.

Getting water to your home

Significant amounts of energy are needed to pump water and wastewater around our region and treat it to high standards for our customers.

Alongside other water companies, we’ve committed to support industry body Water UK’s Net Zero commitment to become carbon neutral by 2030. With a growing population and increased treatment standards, cutting our emissions is challenging. Despite these factors, we’re pleased to be reducing our carbon emissions each year.

Read our Net Zero Plan

You can help by using water wisely. If you only use what you need, less energy is needed to treat water and pump it to and from your home. However, the carbon impact of your water use doesn’t always end when it comes out of your tap. How you use it matters too.

Your household water use

We all rely on water for cooking, cleaning and washing ourselves. Heating the water for these tasks uses energy. Meanwhile, household appliances such as washing machines and dishwashers need power to run.

Fortunately, simple changes can help you reduce the impact of your everyday water use:

  • Could you wait for a full load before you put on a wash, so you run your appliances less often?
  • Have you checked whether your devices have an ‘eco’ setting that uses less water or energy?
  • Making a cuppa? Only fill the kettle with the amount you need – this can cut the energy cost of boiling your kettle by a third.

Get creative and you’ll be amazed how many ways you can save energy while you save water in your home.
