ESSA Technologies Ltd. (ESSA) is a leading environmental consulting firm with over 40 years of experience delivering research, analysis, and strategic advice to address complex natural resource and environmental challenges worldwide. With over 2,900 projects completed in more than 40 countries, ESSA works with governments, Indigenous communities, international organizations, NGOs, and the private sector.
ESSA’s mission is to “bring together people, science, and analytical tools to sustain healthy human communities and ecosystems”. Founded in 1979, ESSA emerged from two complementary worldviews: 1) expanding environmental awareness and policies (Green), and 2) the growing application of rigorous systems analysis to ecosystems, including humans (Blue). By merging these perspectives, ESSA has developed a legacy of applying Adaptive Environmental Assessment and Management (AEAM) principles to environmental assessments, ecosystem restoration, and species recovery in North America, as well as climate adaptation and capacity building in Latin America, Asia, and Africa.
ESSA’s Vancouver headquarters and Ottawa regional office support multidisciplinary expertise across aquatic and terrestrial ecology, Indigenous-led resource management, cumulative effects assessments, GIS and spatial analysis, and decision support. As ESSA guides clients, communities, and ecosystems through today’s environmental challenges, they stay closely connected with academic institutions, sharing real-world expertise with faculty and students. Their commitment to a sustainable Green and Blue planet remains stronger than ever.
