The Environmental Choice Program is Canada's only national and comprehensive ecolabelling program. Environmental Choice exists to help consumers and producers buy and sell "green" products and services certified by the program. The Program's official symbol of certification - the EcoLogo - is a registered mark of Environment Canada. It may only be used in association with products and services that are certified by Environmental Choice. Environmental Choice accredited products are proven to have less of an impact on the environment because of how they are manufactured, consumed or disposed of. Certification of products and services is based on compliance with strict environmental criteria that are established in consultation with industry, environmental groups, independent experts and research into the life-cycle impacts of a product or service.
