    Supplemental material: Exposure disparities by income, race and ethnicity, and historic redlining grade in the greater Seattle area for ultrafine particles and other air pollutants

    This environmental health study examines how exposure to ultrafine particles and other air pollutants varies across the greater Seattle area based on income, race and ethnicity, and historical redlining grades assigned by the Home Owners' Loan Corporation (HOLC). Researchers analyzed pollutant concentration data from 2019-2020 alongside census and demographic data to identify disparities between communities. The supplemental materials include statistical tables and scatterplots supporting the main findings on environmental inequality across Seattle neighborhoods.

    Characterizing Ultrafine Particulate Matter and Black Carbon Exposure Levels for a Seattle-Based Cohort From a Mobile Monitoring Campaign

    This research presentation describes a mobile air monitoring study conducted in Seattle to measure ultrafine particulate matter and black carbon pollution levels for elderly residents participating in the Adult Changes in Thought (ACT) study, which investigates aging and dementia. Researchers used a vehicle-mounted monitoring system to collect repeated short-term air quality samples across the Seattle area, aiming to estimate long-term pollution exposure for cohort participants aged 65 and older. The study is funded by the National Institute of Environmental Health Sciences and the National Institute on Aging.

    2005 inventory of Seattle greenhouse gas emissions: Community & corporate

    This 2005 report from the City of Seattle's Office of Sustainability and Environment measures greenhouse gas emissions across the Seattle community and city government operations. It uses two approaches: a geographic inventory tracking emissions within Seattle's boundaries, and a corporate inventory covering the city government's facilities and operations. The report was compiled by consultant Roel Hammerschlag and audited by Envirometrics, Inc., serving as a baseline reference for Seattle's climate planning efforts.

Read This!

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.
