The Greenfox5 model is an easy way for young people to understand sustainability issues. It is a holistic model that breaks down the aspects of sustainability into five easy to understand categories: Products, Food, Energy, Waste, and Greenspace. This allows students to see the big picture, while providing them a framework to think creatively within those categories to problem solve and create innovative solutions.

Greenfox Schools believes that these categories are the five main functional points in schools that can be optimized to benefit the environment, and taught to students to explain sustainability. PFEWG™ is an acronym we also use to express the model based on the five categories.
