The GreenTools program is designed to help all King County stakeholders green their built environment while addressing critical environmental issues, such as global warming, habitat restoration, solid waste reduction, and community planning. GreenTools provides technical assistance, hands-on training and policy development through community partnerships in public and private sectors.

GreenTools puts practice to work through community engagement; believing that a sustainable community is one that works harmoniously to create a balance between equity for people, economy and environment. The community uses its resources to meet current needs while benefiting future generations. We conserve natural resources and their richness through prioritizing human health, eliminating waste, preventing pollution, maximizing conservation and promoting prosperity in our local living economy.

This site will serve as a resource for all kinds of green building information ranging from case studies to technical references. You will find information on green building certification programs, construction and demolition recycling and reuse, deconstruction techniques, incentives to build green, and much more. Be sure to check the documents and links pages for resources on a variety of green building topics.
