Britain’s Queen Elizabeth has signed up to a carbon-cutting club.
The Royal Household – which runs royal residences Buckingham Palace, St James’s Palace, Kensington Palace and Windsor Castle – have joined a not-for-profit network of companies which swap ideas and techniques to lower their carbon footprint.
A Buckingham Palace spokesperson said: "The Royal Household always looks at ways to improve its energy consumption and environmental impact.
"It is an excellent opportunity to join with like-minded organisations to share ideas and discuss best practice regarding energy and carbon-saving initiatives."
The Royal Household is one of 85 members of the programme, which was set up by the National Trust and sustainable energy charity Ashden last year and also includes the Church of England and Oxford University as members.
The organisations combined look after 18 world heritage sights and a large area of the UK and through site visits, work shops and evaluations, share advice about energy saving and renewable projects.
Helen Ghosh, head of the National Trust, said: "To look after the landscapes, wildlife and heritage we love as a nation, we need to do everything we can to reduce carbon emissions.
"When you see years of coastal erosion take place in a matter of months and are battling the destruction of flooding, new pests and diseases on our natural and historic heritage, you have to be concerned about climate change and its effects."
