Sustainable Seattle works to build a thriving future through initiatives that deliver environmental, economic and community benefits, promote equity, and build resilience.

Our 2020 Vision

Seattle anchors a region in which all residents, organizations and businesses are engaged, empowered and collaborating to secure a sustainable, equitable and resilient future.

How We Define Sustainability:

We define sustainability as long-term social, economic and environmental vitality that meets the needs of the present without compromising the health of future generations.

Sustainability Indicators

We have worked to develop five sets of community-based indicators over the past 25 years, measuring and making progress towards sustainability.   Our indicator reports have reached thousands of people and sparked the formation of many other community sustainability groups throughout the world.  We believe that sustainable urban development is one of the most pressing challenges facing the human community in the 21st century.

In practice, we seek to balance concerns for social equity, ecological health, and economic vitality to create livable communities today while ensuring a healthy and fulfilling legacy for our children’s children.  Our flavor of sustainability comes directly from the people of the Central Puget Sound and is neatly summed up by the sustainability indicators, goals, data, and actions that are a product of participatory action research fundamental to Sustainable Seattle.
