A 2018 Boeing presentation by Senior Manager Robert Stoker outlines the aviation industry's progress in reducing aircraft noise and fuel consumption, noting roughly a 90% reduction in noise footprint and 70% improvement in fuel efficiency since the 1950s. The document highlights Boeing's current fleet — the 737 MAX, 747-8, 787, and 777X — each delivering significant reductions in both noise footprint (ranging from 30% to 60% smaller) and fuel/CO2 emissions compared to the models they replace.

Technical report showing aircraft engine emissions data for different aircraft types (A300, 757, 737) across various operational modes including takeoff, taxi, climb, and approach phases. Contains detailed emissions measurements for CO, HC, NOx, SOx, and particulates in kg/hr/engine units.

A 1990 environmental assessment by Roy F. Weston Inc. evaluated soil and groundwater quality on an undeveloped Seattle property along the Duwamish Waterway, where Boeing was considering a 50-year lease with Seattle City Light. The study examined areas where dredged sediment from the Duwamish Waterway had been deposited in 1968 and 1985, testing for contaminants including PCBs, pentachlorophenols, PAHs, and metals. Prior sampling had found contaminant levels generally below state-regulated thresholds, and this baseline assessment was conducted to document existing conditions before any lease agreement was finalized.

This 1981 Memorandum of Understanding between the Port of Seattle and King County outlines terms for reclassifying approximately 30 acres of land on the west side of Sea-Tac International Airport to allow Boeing to develop a Corporate Headquarters Facility. The agreement includes provisions for the Port to lease 5 acres to King County for a neighborhood park at $1 per year, and restricts development on an adjacent 55-acre greenbelt buffer zone for at least 10 years. The document also affirms King County's zoning authority over non-airport-related land use at Sea-Tac and establishes a dispute resolution process between the two agencies.
