In 2010, after three year's work with the Carbon Trust, Guy's
and St Thomas' NHS Foundation Trust has realised a 20% year on year
carbon emissions' reduction (double the NHS target for the same
period). As a result, it has cut its energy bills by over £1.7
million a year.
In recognition of these achievements, the hospital has gained
the Carbon Trust Standard and become
a Platinum Award member of the Mayor of London's Green500
The business case
Guy's and St Thomas' is one of the busiest NHS Foundation Trusts
in the UK, employing around 10,000 people and serving over 850,000
patients every year. By 2004, the Trust was spending roughly £10
million a year on energy, a cost that was growing rapidly due to
rising energy prices.
Our Carbon Management programme helped Guy's and St Thomas'
identify its carbon footprint and then to quantify new and existing
proposals to reduce carbon emissions and consolidate them under one
Key activities undertaken, which were funded by a £2m
investment, include the installation of the largest combined heat
and power (CHP) capacity in the NHS, the addition of energy
efficiency measures during the refurbishment of the Guy's Tower,
updates to the hospital's catering and laundry facilities,
improvements to the heating and lighting controls, and the
extension of the hospital's building management system to
previously unconnected areas.
