The state of Washington has had a series of single-use bag ordinances at the local level over the past 10 years, which Surfrider works to culminate in a statewide law.
Washington passed legislation the eliminate single-use carryout bags. This bill allows retailers — including grocers — to provide paper bags or reusable, plastic film 2.25 mil bags for 8 cents each. The reusable bags must meet standards for strength, durability and recycled content. The 8-cent pass-through charge will help retailers recover the costs of the paper or durable plastic bags and create an incentive for shoppers to bring their own bags. In 2026, the allowed plastic film bags would increase in thickness from 2.25 to 4 mil and the pass-through charge would increase to 12 cents.The bill passed in March 2020 with strong bi-partisan support by a vote of 67-29 in the House, and a concurrence vote of 35-15 in the Senate.
