Corporate Responsibility

Working with others.

Last reviewed:

Our employees and alliance partners play an essential role in our journey to becoming more sustainable. We want to make it easy for our teams to make more sustainable choices in how we respond to the challenges of tackling climate change.

An important part of this is the need to work with other organisations to develop resilient responses to the impacts of climate change, and to reduce our greenhouse gas (GHG) emissions. We know we can’t do this alone, so we’re continuing to work collaboratively with our customers, employees, partners, suppliers and regulators to create opportunities to better understand what we can do.

Our thought leadership.

During 2017/18 we’ve carried on working closely with a range of other organisations to tackle the issue of climate change and lead debate. Some of these partners have been:

  • The Aldersgate Group.
  • The Prince of Wales Corporate Leaders Group on Climate Change.
  • Business in the Community.
  • The Thames Water Customer Challenge Group.
  • Defra.
  • London Climate Change Partnership.
  • The Climate Change Committee’s adaptation sub-committee.
  • Action for the River Kennet (ARK).
  • WaterUK.
  • UKWIR.
  • BEIS.
  • Haven Power.
  • A range of academic institutions including the University of Oxford and Imperial College.

Delivering increased resilience.

We’ve challenged our alliance partners to help us become more resilient and minimise both the operational and embodied carbon impacts of all their programmes. We’ve made progress towards our ambitious goal of reducing our GHG emissions to 34 per cent by 2020.

We’ve reduced our gross greenhouse gas emissions by 27% down to 616,731 kTCO2e compared to 1990 levels despite having around 3 million more customers. Our net greenhouse gas emissions have reduced by 67% to 277,328 kTCO2e#. We generated 293GWh of the electricity we used from renewable sources equivalent to a £30 million energy cost saving. Despite this, we weren’t able to meet our target of reducing our grid electricity consumption, which increased by 140 GWh during the year. This increase was mainly due to increased service demand.

After we installed Europe’s largest floating solar panel array on our Queen Elizabeth II (QE2) reservoir, it’s been providing renewable electricity to our Hampton Water Treatment Works. Last year the QE2 array supplied a total of 14% of Hampton’s electricity needs, peaking on sunny days when demand for Hampton’s water was highest. At its peak output it supplied 44% of the site’s daily needs, and 100% of the site’s needs for 3.5 hours a day.

#From October 2016 our net operational emissions account for the grid electricity we imported being 100% REGO accredited renewable. We use the governments REGO (renewable energy guarantee of origin) accreditation scheme to demonstrate the electricity we consume is from a renewable source.
