Kath has been Chief Executive of Sustain: The alliance for better food and farming, since 2016. She is leading the alliance's response to Brexit and its profound implications for healthy and sustainable food, farming and fishing. She is also a member of the London Food Board and helped establish the Sustainable Food Cities Network. She is a vocal advocate of high standards for food, environment and animal welfare, and champions better trading practices and government support to reward food producers and workers for all the benefits they generate. Kath instigated Sustainable Fish Cities to persuade major foodservice companies to serve only sustainable fish; and the Right to Food initiative to address food poverty systematically so that everyone can eat well. She also helps run the Campaign for Better Hospital Food, and sits on Defra’s food procurement taskforce. On a voluntary basis she serves on the board of Growing Communities, an award-winning community-run sustainable food trading enterprise based in Hackney.
