Safeguarding the environment

We are committed to reducing energy’s contribution to climate change while ensuring we manage our wider environmental impact on water, waste and biodiversity.

With around 90% of our carbon emissions arising from customer energy consumption, the greatest contribution we can make to combatting climate change is to give customers greater choice and control over their energy.

We are doing this by:

  • Delivering innovative products and services that give customers greater insights and control over how they use and generate energy through our Connected Home and Distributed Energy and Power businesses.
  • Providing alternatives to fossil fuels with renewable or low carbon energy, such as with solar generation.
  • Installing energy efficiency measures such as insulation, which provide a cost-effective way to keep homes running while contributing towards our fulfillment of the mandatory Energy Company Obligation

reducing our carbon emissions

We emit around 60% less carbon for every pound of revenue raised than in 2010, having gradually shifted away from being a large-scale energy producer.

We endeavor to effectively monitor, manage and reduce our carbon emissions through technology, innovation and cultural change. As part of this, we are targeting reductions in our Central Power Generation carbon intensity by 55% by the end of 2020 (baseline: 2008). We are also reducing our internal carbon footprint by 20% by the end of 2025 (baseline: 2015). See our data centre to explore our performance.



We monitor and manage our water usage, waste production and ecological impact, seeking to reduce our impacts where possible.


We recognise that water availability is an increasingly significant issue for global stakeholders and we are committed to increasing the visibility of our water footprint, as well as reducing our water impact through robust environmental management.

Water, however, remains a non-material risk for our business because, for a company our size and within our sector, we consume a relatively small amount of water and do not operate water-intensive activities in water-stressed areas.

To improve the visibility of our water footprint and show how we effectively manage our impact, we participate in CDP’s Water Disclosure Project. In 2017, we maintained our place on CDP’s Water A List.

See our data centre for more information on our water use.


We have processes and controls in place across our business to effectively manage and mitigate the waste we produce.

We also have a 20% stake in the nuclear power generator EDF Energy Nuclear Generation Group Limited. While we do not operate the facilities, we choose to report data on nuclear waste relating to our stake. 

All of EDF's power stations are granted authorisations to dispose of radioactive waste by either the Environment Agency or the Scottish Environment Protection Agency. Nuclear waste is treated in a number of ways to reduce volumes before being disposed of or sent for recycling.

Although our impact on biodiversity is not a material issue for us as a company, we recognise our responsibility to manage the impacts of our operations, particularly in our energy sourcing and generating activities where the potential impact on biodiversity is greatest.

We are committed to conducting environmental impact assessments and developing action plans that involve our employees and local communities, where possible, to manage these impacts in line with our Group Environment Policy.

Air quality

We aim to reduce the amount of air pollutants across our operations. The combustion of natural gas in power generation releases pollutants such as nitrogen oxides, Sulphur dioxide and particulate matter that can impact air quality.
