Zero Waste Canada was founded on the principles of Zero Waste as defined by the Zero Waste International Alliance.  The Zero Waste Hierarchy 5.0 was adopted by the International Zero Waste Alliance in January 2013 and was revised and adopted by Zero Waste Canada in 2014.  Its current version 6.0 was adopted by both the Zero Waste International Alliance and Zero Waste Canada in December of 2014.
The Zero Waste Hierarchy describes a progression of policies and strategies to support the Zero Waste system, from highest and best to lowest use of materials.  It is designed to be applicable to all audiences, from policy-makers to industry and the individual.  It aims to provide more depth to the internationally recognized 3Rs (Reduce, Reuse, Recycle); to encourage policy, activity and investment at the top of the hierarchy; and to provide a guide for those who wish to develop systems or products that move us closer to Zero Waste.  It enhances the Zero Waste definition by providing guidance for planning and a way to evaluate proposed solutions.
