Spire Healthcare this month began procuring all its electricity from renewable sources as part of its commitment to go carbon-neutral by the end of 2030.
It believes it is the first provider in the sector to do so and anticipates this will result in a 40% reduction in its carbon emissions.
A range of other initiatives include:
Replacing gas-powered boilers with more efficient equipment powered by electricity;
Replacing older lighting with LED lights which are between 50 and 60% more energy-efficient;
Installing photo-voltaic solar panels on the roof at Spire Cardiff, with similar projects to follow at other Spire hospitals;
Use of electric vehicles as part of its fleet;
Improved insulation in its buildings.
The group has also appointed and trained a colleague from each of its 39 hospitals to become a carbon champion with the aim of developing and promoting local initiatives for reducing carbon consumption.
