The “hub” of the Sustainability Wheel® represents the epicenter to which all of the other components are attached. The center-the hub-must be very strong in order for the wheel to smoothly support the bumps in the road and traverse the inevitable “road hazards” that could block our organization’s path to a sustainable future. Respect is part of the hub. It is that connection between the corporate (organizational level) mission/vision and the organization’s sustainability mission/vision.
