    Boeing allowed to keep making 777 freighter despite climate rules

    By Lauren Rosenblatt Seattle Times business reporter The Federal Aviation Administration last week granted Boeing’s 777 freighter a few more years of production, waiving looming emissions requirements for up to 35 new aircraft. Without that exemption, Boeing would have had to sunset production of the Everett-built 777 freighter in 2028 because the cargo plane would

    Emissions Forecast: Traffic Growth Outpaces Fleet Renewal Improvements 

    IBA’s Sustainability Watch: September 2026 Written by Archie Brown, Senior Analyst IBA’s sustainability team has modelled commercial passenger aviation emissions through to 2050, also including our own state-policy baseline scenario in the analysis. Rather than applying a top-down growth rate, it combines IBA’s aircraft series-level delivery and retirement forecast with projected demand, utilisation and load

    By AYA DIAB It feels simple: You shop, find something you want and click to buy. It shows up today, overnight or tomorrow. We’ve gotten used to that speed. But that convenience comes with a climate cost. Multiple factors shape the environmental toll of a delivery. These include the distance from a fulfillment center, whether

    Puget Sound Region Final Comprehensive Climate Action Plan

    The Puget Sound Region Final Comprehensive Climate Action Plan, published December 1, 2025 by the Puget Sound Clean Air Agency, outlines greenhouse gas reduction strategies for King, Kitsap, Pierce, and Snohomish Counties in the Seattle-Tacoma-Bellevue metropolitan area. The plan covers six sectors—Built Environment, Transportation, Municipal Solid Waste and Wastewater, Natural and Working Lands, Refrigerants, and Consumption—with goals, emission projections, and workforce planning analysis. Note that this document focuses on regional climate and air quality policy rather than Sea-Tac Airport noise regulations specifically.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
