Sustainable Purchasing

Sustainable Purchasing

King County is committed to procuring goods and services which balance fiscal responsibility, social equity, and environmental stewardship. When available, we specify products designated with an "ecolabel" that meet environmental standards and certifications. Beyond purchasing established products, we seek out innovative products and services which help lessen our environmental impacts.

Tips for Success

Understand what sustainable attributes we look for when purchasing goods and services in our Sustainable Purchasing Guide.

Find out which products and services we have green contracts for in our Awarded Contracts List, which denotes contracts with sustainable attributes.

See King County's Sustainable Policies here.

These policies include the county's Strategic Climate Action Plan, Green Building Ordinance, and Equity and Social Justice Strategic Plan.

When purchasing goods and services, we prioritize ecolabels recommended by the U.S. Environmental Protection Agency (EPA) and those accredited by third-party organizations. Find the standards and certifications we look to on our Ecolabels page.
King County encourages its purchasers to look for these sustainable business certifications when deciding which supplier to select.

Submit your sustainable product or service to one of King County's open solicitations.

These solicitations include contracting opportunties for providing sustainable goods and services, as well as green building design and construction opportunities.
