Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what assessment his Department has made of the potential role of water efficiency measures in helping achieve the Government’s net zero aims.

As outlined in the Energy-related Products Policy Framework, the Government estimates 0.9 million tonnes of CO2 equivalent could be saved over Carbon Budget 5 through consumer behaviour change encouraged by a mandatory water label on taps and non-electric showers.

Defra has already committed to mandatory water labelling on taps and non-electric showers, among other products, and is working closely with BEIS officials to explore the inclusion of energy efficiency information on the labels in order to best support consumers to make energy- and money-saving purchases.

The Government will continue to explore the feasibility of other efficiency measures for these products.
