Willamette Partnership oversees the Ecosystem Credit Accounting System, a package of protocols, tools, and resources that allow buyers and sellers to track, account, and trade in multiple types of ecosystem credits.

The Ecosystem Credit Accounting System was developed by the Partnership but represents agreement among federal, state, and local agencies, conservation organizations, and other stakeholders, including many of those likely to buy or sell credits through an ecosystem credit trading or tracking system.

The Ecosystem Credit Accounting System supports credits for water quality and habitat benefits and was built to provide:

  • A more efficient and effective use of conservation investments, both from regulated and voluntary sources;
  • Opportunities to accommodate growth without environmental degradation;
  • Increased coordination among various conservation efforts;
  • Incentives for voluntary actions on private lands; and
  • Healthier ecosystems and improved conservation outcomes.

Twenty-five key organizations agreed to pilot the protocols and tools governing the Accounting System through a Joint Statement of Agreement.
