Established in 1955, the members of the association share with all Canadians the responsibility of maintaining the integrity of our environment now and for the future. Responsible stewardship of our resources, be they related to air, land or water, is supported by members of WPC. In the spirit of environmental responsibility and sustainable development, WPC members have endorsed the following set of principles to govern their attitude and action in environmental matters:

• WPC members will endeavour to produce quality products which, when used correctly have no adverse effects on health and safety of the public or the environment.
• WPC members will assess, plan, construct and operate facilities in compliance with all applicable regulations.
• Sound management and production practices will be applied by WPC members to advance environmental protection in the absence of regulatory statutes.
• Research and development of new products and processes that further minimize environmental impact will be encouraged.
• Environmental awareness and responsibilities will be promoted amongst employees of member firms and the public.
• WPC will work with all levels of government in the development of regulations and product standards based on sound, economically achievable technologies, and determination of environmental impact.
