Sustainable Purchasing Program

About our program

SPLC_Founder_BLUE

King County requires its agencies and contractors to purchase sustainable products and services. This means prioritizing products and services that provide the greatest overall environmental, social, and economic benefits.

To support these policies, the county’s Sustainable Purchasing Program provides staff with guidance and technical resources. These include tools like the Sustainable Purchasing Guide, which helps employees:

  • Identify sustainable features in products and services
  • Understand required environmental standards and certifications (ecolabels)
  • Locate contracts that offer sustainable products and service providers

Together, these resources help staff and contractors make purchasing decisions that align with the county’s sustainability goals.

Sustainable Purchasing Guide

This guide balances economic, social, and environmental purchasing considerations. Search the Guide

There are 5 steps for sustainable purchasing:

Before buying, ask:

  • Can you avoid the purchase?
  • Can you reuse or repurpose what you already have?
  • Can you find it secondhand at Surplus?

Check the Surplus warehouse (707 S. Orcas St) or add items to your wish list. Email kcsurplus@kingcounty.gov. You’ll be notified if the item arrives. These items are free.

Need furniture? Try the Facilities Management Division’s "New to You Market" pilot for used furniture that can be redistributed to you for free or low cost.

 

 

If you must buy:

  • Check for "green" contracts on the Awarded Contracts Log that have sustainable products or services on them, even if under $10,000.These are pre-negotiated deals. Look for the green heart symbol and added comments that explain the sustainable features
  • Don't see what you need? You can "piggyback" off a contract from another public agency or national cooperative group to save time. (internal use only)

Look for products and services with these features:

  • Have ecolabels (certified to environmental standards)
  • Made with recycled content
  • Recyclable or compostable
  • Reusable or durable
  • Resource efficient -- save water and energy
  • Low volatile organic compounds (VOCs)
  • Biobased materials
  • Electric instead of gas powered
  • Refurbished
  • Rent or lease instead of buy
  • Free of per and polyfluoroalkyl or "PFAS" (chemicals of concern)
