Cascadia Consulting Group is a women-owned environmental consulting firm founded in 1993 and based in Seattle, WA and Oakland, CA. Cascadia began as a recycling and materials management consulting firm, providing research, planning, evaluation, and program implementation services to public, corporate, and higher education clients. Over the past three decades, Cascadia has expanded its expertise to fill a growing demand for integrated services that address upstream and downstream materials management needs as well as energy use, water conservation, stormwater pollution prevention, low impact development, community resilience, and climate change.

Cascadia is a national leader in integrated waste reduction and zero waste planning services, from upstream policy research and waste characterization studies to downstream outreach, behavior change, and technical assistance. We’ve worked with thousands of clients and communities—from individual buildings and businesses to statewide and national agencies—to understand waste flows, optimize diversion opportunities, and develop and implement programs that move the needle.
