The mission of the Sustainable Food Trust is to accelerate the transition towards more sustainable food systems by working catalytically to influence and enhance the actions of others. Our theory of change is informed by the belief that policymakers, businesses and civil society organisations will be empowered to act when there is strong evidence, supported by pressure from informed public opinion. Therefore, we work from the top down and from the bottom up, and we ensure our messages are grounded by good science.
