The blue footprint symbol is used to show low carbon meals
King's Conference & Dining Department has adopted the University of Cambridge Colleges Low Carbon Meals Scheme.
The aim of the scheme is to make people more aware of the environmental impact of producing, transporting and storing food.
In the UK, up to a fifth of people's annual carbon footprint comes from the food they eat. By labelling low carbon dishes, the scheme hopes to encourage College members to choose food that has produced fewer carbon emissions.
Foods with the lowest carbon emissions include local seasonal vegetables, cereals and fruit. Food that produce higher greenhouse gas emissions include beef, lamb, hard cheese and frozen meals.
