The National Trust is giving all its staff and volunteers a day off on February 29th to encourage them to take action to reduce their carbon footprints.
All Trust staff are being given the opportunity to spend the day at home or in their local community on Leap Day, making changes to improve their environmental footprint - from switching to energy saving lightbulbs to establishing a compost heap.
"At the National Trust, we are looking at the impact of all our activities and how we can reduce this impact. Now we want our staff to do the same."
The Trust also helps to encourage other businesses and organisations to follow suit in encouraging their employees to live greener lifestyles.
Fiona Reynolds added: "There are over 29 million employees in the UK; if just one million changed one light bulb and turned their thermostat down by one degree, it would save 351,000 tons of carbon."
