ESSA brings together people, science and analytical tools to sustain healthy ecosystems and human communities. We envision a world where creativity, a focus on learning, and systems-thinking are the foundation of solutions to environmental challenges.

ESSA began in 1979, building on ideas developed at the University of British Columbia about how to creatively apply science and systems thinking to help people tackle complex environmental and social problems. We have been evolving and applying these ideas for more than 35 years and have completed over 2,400 projects in North America and other parts of the world, making a difference to people and the planet.
