Researchers from the University of Washington presented findings to King County's Airport Round Table Advisory Committee showing that aviation emissions pose significant public health risks to nearby communities. Airports account for 70% of airborne lead emissions in King County, primarily from piston-engine aircraft burning leaded aviation gasoline, and multiple studies link living close to such airports with elevated blood lead levels in children. The presentation also highlighted broader health harms from aviation pollutants—including ultrafine particles and nitrogen oxides—affecting neurological, cardiovascular, and respiratory health.

The Port of Seattle's 2024 Environment & Sustainability Annual Report, presented on April 25, 2025, outlines the agency's efforts to build a more sustainable and resilient port through six strategic priorities. These include reducing emissions and waste from port operations, attracting clean fuels for maritime and aviation, protecting water quality, and engaging communities. The report covers both aviation and maritime sustainability initiatives led by the Port's Environment and Sustainability team.

The Aviation Noise and Emissions Mitigation Act, introduced by Rep. Adam Smith (WA-09), aims to help communities near airports — including those around Sea-Tac — deal with the health risks posed by aviation noise and air pollution. The bill would create two EPA grant programs: one funding research and neighborhood-level monitoring of noise and emissions, and another supporting mitigation efforts such as home soundproofing, public health programs, and healthcare services for affected residents. The legislation responds to studies linking airport emissions to increased risks of cancer, heart disease, and asthma, as well as findings that aircraft noise negatively affects children's learning.

The Aviation Noise and Emissions Mitigation Act, introduced in the 119th Congress by Rep. Smith of Washington, would direct the EPA to establish a 3-year pilot grant program to measure aircraft and airport noise and emissions—including greenhouse gases, particulate matter, and ultrafine particles—in communities near airports and flight paths. Grant recipients would use advanced monitoring technology to trace pollution to specific sources, produce neighborhood- and ZIP Code-level data, and work with local agencies and community organizations to develop mitigation strategies. The program is designed to be replicable nationwide, with a focus on identifying and protecting frontline and disproportionately impacted communities.

Overview document from the Cascadia Sustainable Aviation Accelerator (CSAA), a public/private trade organization focused on de-risking the regional sustainable aviation fuel (SAF) value chain across Washington, Montana, Oregon, Idaho, and British Columbia. Covers SAF as the only viable drop-in replacement for conventional jet fuel over the next 40+ years, the barrier of commercial-scale production, and

The Aviation Environmental Design Tool (AEDT) Version 3g is a Federal Aviation Administration software system used to model aircraft operations and calculate their environmental impacts, including noise, emissions, and fuel consumption. This Quick Start Tutorial guides users through building basic noise and emissions studies, covering steps such as adding airports, creating flight tracks, setting up receptors, and running metric results. The tool is relevant to airport noise policy analysis, as it provides a structured method for quantifying and evaluating the environmental effects of aviation activity around airports like Sea-Tac.
