2018-06-01Puget Sound Clean Air Agency Greenhouse Gas Emissions Inventory
This 2018 report by Cascadia Consulting Group inventories greenhouse gas emissions across the Puget Sound region, covering sources such as transportation, buildings, industry, solid waste, water, and agriculture for the year 2015. It outlines the methodology, data sources, and findings used to measure the region's carbon footprint. While focused on regional air quality and climate impact, it provides context for understanding emissions contributors in the greater Seattle–Tacoma area. -
2018-02-07Aviation-related impacts on ultrafine particle number concentrations outside and inside residences near an airport
A study of residences near Boston's Logan International Airport found that jet engine exhaust significantly raises ultrafine particle concentrations both outdoors and indoors, with levels roughly 1.7 times higher when winds blow from the airport's direction. Researchers monitored 16 homes located 4–6 km from the airport and confirmed that aviation-related particles penetrate inside residences, posing potential health risks to nearby communities. While focused on Logan Airport, the authors note these findings are likely applicable to other major airports, including those in dense urban areas. -

Educating Voters Environmental Priorities Coalition Lobby & Advocacy A series on protecting all communities from dangerous pollution. For 50 years, Washington Environmental Council has set our sights on a cleaner, brighter future and charted a path to get there. In 1988, WEC campaigned to pass Initiative 97 (commonly called the Model Toxics Control Act or -
2017-05-11Modeling variability in air pollution-related health damages from individual airport emissions
Researchers used advanced air quality modeling to estimate the health impacts of emissions from 66 U.S. airports, including how pollution from each individual airport contributes to premature deaths. The study found wide variation in health damage across airports, driven largely by nearby population density and local atmospheric conditions. These findings can help inform emissions control policies at specific airports to better protect public health. -
2016-07-15Air Quality Criteria Pollutant Emissions Inventory Task 2.8: Working Paper – Documentation of Assumptions
This 2016 working paper documents the methods and assumptions used to build an air quality emissions inventory for Seattle-Tacoma International Airport as part of the Sustainable Airport Master Plan. Using the FAA's EDMS modeling software, analysts estimated pollution from sources including aircraft engines, ground support equipment, parking, and stationary facilities such as generators and boilers. Aircraft operation data for 2014 was gathered from multiple sources, including FAA tower records, airline guides, and the Port of Seattle's own noise monitoring system. -

Obama’s Climate Betrayal
Elizabeth Kolbert Some international disputes are significant for symbolic reasons, others for substantive ones. The current conflict between the United States and the European Union over airline-emissions limits is both. Unfortunately this means that the U.S. is doubly on the wrong side. The Obama Administration ought to be applauding the Europeans. Instead it’s threatening a -
2011-12-082008 King County Community Greenhouse Gas Emissions Inventory: “Geographic Plus” Methodology
This 2011 report by the Stockholm Environment Institute estimates King County, Washington's greenhouse gas emissions for 2008 using a 'geographic plus' methodology, covering sources such as transportation, buildings, industry, and waste. Total emissions reached approximately 23.4 million metric tons of CO2 equivalent in 2008, a 5% increase from 2003, with transportation accounting for roughly half of all emissions. The findings were used by King County and its partners to identify major emission sources and develop strategies to meet community greenhouse gas reduction goals.
