ecoPRO Guiding Principles

United States Environmental protection Agency (from USEPA):

Sustainability is based on a simple principle: all that we need for our well-being and survival depends directly or indirectly on our natural environment. Sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony; that permits  fulfilling the social, economic and other requirements of present and future generations.

Brundtland Commission of the United Nations 1987:
Sustainability is design, construction, operation and maintenance practices that meet the needs of the present generation without compromising the ability of future generations to meet their own needs.

Sustainable Landscaping is the designing, constructing, and maintenance of landscapes to conserve and regenerate water, air, soil, plant and wildlife resources; protect and enhance human health and wellbeing. Sustainable practices focus on the environment of an ecoregion while striving to be socially equitable and economically feasible.

Sustainable Landscape Practice is the use of ecologically sound principles to work within natural ecoregional systems. It encourages working within closed systems with regards to organic matter and nutrient cycling.

The goal of sustainable landscape practice is to design, construct, and maintain landscapes that will be aesthetically appealing and ecologically resilient in the ecoregion they are located.

ecoPRO Certified Sustainable Landscape Professionals have passed an exam that tests their knowledge of sustainable landscaping principles and practices. They conform to the ecoPRO Code of Ethics in designing, constructing, and managing landscapes with the most current and ecologically sound principles. Where possible, ecoPRO Certified Sustainable Landscape Professionals collaborate across the various disciplines for design, construction, and maintenance.

Best practices designated with a diamond indicate a “core” best practice that ecoPRO certified professionals should employ where applicable, at all times. Since many practices use multiple principles, the righthand columns link the practices to the applicable principles.  Some of the best practices are duplicated. Underlined terms are defined in the ecoPRO Glossary on page 27.

ecoPRO sustainable best practices as much as possible align with existing business and site certifications. There are several sustainable certifications applicable to landscape sites and businesses in Washington State. Some of them are:

    • EnviroStars—a certification for businesses that reduce the input and use of toxics in the environment.

    • Salmon Safe—a land management certification for sites that protect water quality, preserve and restore habitats
    • The regional BuiltGreen, national LEED, and Living Building Challenge–green building certifications that include site development best practices.
    • Greenroads—for road construction; and Envision—for infrastructure projects
