One of Natural Fitnesses founding principles is to tread lightly on the earth. They aim to offset the environmental impact that results from the manufacturing and distribution of their products. To achieve this, the company created their Zero Impact Program (ZIP). While Natural Fitness is always looking for new and creative ways to offset their eco-footprint, here is what the company is currently doing: Plant-A-Tree Initiative. They seek to offset the eco-footprint of their employees and offices. They strive to offer the most environmentally-friendly products available. Natural Fitness helped create the Chicago Biodiesel Co-op, which educates, promotes and produces locally-derived biofuels.
