A pub in the Lake District is one of the first to list their food in accordance to their carbon footprint.
Sticklebarn, owned by the National Trust, use a calculator that works out how much carbon dioxide is in each dish on the menu, in an attempt to try and reduce the environmental impact of the Trust's pub.
On average each person in the UK produces nine kilograms of carbon dioxide a day - through eating and drinking. The menu includes a black bean burger and an apple and walnut salad with baked polenta - both less than kilogram of carbon dioxide.
Dishes with meat range between two to five kg of carbon dioxide.
Last year, the Lakes pub was awarded two out of three stars by the Sustainable Restaurant Association - a not-for-profit organisation, providing restaurants with advice and support to work towards sustainability.
