February 26, 2026
The Sound Transit Board today formally adopted the agency’s 2026–2030 Sustainability Plan, setting measurable climate, community impact and operational reliability goals that guide the regional transit system’s growth through 2030 and beyond.
The plan outlines how the agency integrates sustainability into every stage of planning, designing, building, and operating a growing regional system that connects residents to the places they live, work, and play. The adopted motion further strengthens these commitments by sunsetting the purchase of fossil fuel-powered revenue vehicles and equipment by 2030, advancing fleet electrification and reducing emissions across operations.
