The Telegraph reports a National Trust pub has become the first in Britain to put the carbon footprint of each meal next to the item on the menu. The greenhouse gas emission calculations were made by Professor Mike Berners-Lee, a leading expert on greenhouse gases, and the brother of World Wide Web inventor Tim Berners-Lee.

Sticklebarn in Cumbria – which is run by the National Trust – made the change earlier this year as part of their pledge to run a sustainable business.
