Tristram is the winner of the international environmental award, The Sophie Prize 2011, for his fight against food waste. In his book, Waste: Uncovering the Global Food Scandal (Penguin, 2009), he revealed that Western countries waste up to half of their food, and that tackling this problem is one of the simplest ways of reducing pressure on the environment and on global food supplies. Tristram set up the Feeding the 5000 campaign in 2009 and continues to work with a range of NGOs, governments, and businesses internationally to tackle the global food waste scandal. Tristram will be contributing to FUSIONS’ work of developing a unified definition and quantification method of food waste and will be overseeing the delivery of the Feeding the 5000 events and campaigns in a number of EU countries.
