An analysis of FAA and industry data argues that the 'Greener Skies' flight procedure changes at Seattle-Tacoma International Airport provided negligible environmental benefits, saving only about 1.6 million gallons of fuel annually — less than one-third of one percent of the airport's total fuel consumption. Meanwhile, actual fuel use at Sea-Tac grew by hundreds of millions of gallons per year due to increased flight operations, completely overshadowing the claimed savings. The article contends that the program was essentially a public relations campaign that shifted noise burdens onto surrounding neighborhoods without delivering meaningful environmental improvements.

In April 2017, the Federal Aviation Administration (FAA) presented a NextGen briefing to the Port of Seattle Commission, outlining the agency's initiative to modernize the U.S. air traffic system. NextGen aims to improve safety, reduce flight delays, cut fuel consumption and emissions, and handle growing air travel demand. The briefing is relevant to Sea-Tac Airport stakeholders as these airspace changes can directly affect flight paths and noise impacts on surrounding communities.

A 2013 U.S. Government Accountability Office report found that the FAA made limited progress in modernizing the air transportation system through its NextGen initiative, with ongoing challenges reducing expected benefits. The report highlights the FAA's Greener Skies project at Seattle-Tacoma International Airport, initiated by Alaska Airlines, which aimed to shorten flight paths and route aircraft over water to save fuel, but excluded certain eastern flight procedures due to community concerns about aviation noise. The report notes that the full benefits of new flight procedures depend heavily on how often airlines and pilots actually use them.

In March 2013, FAA Administrator Michael Huerta sent letters to key members of Congress reporting on the FAA's strategy to accelerate implementation of NextGen air traffic management capabilities developed through the Greener Skies project. The report was submitted as required by Section 225 of the FAA Modernization and Reform Act of 2012, and draws on recommendations from the RTCA NextGen Mid-Term Implementation Task Force 5 report issued in September 2009. The Greener Skies project aimed to modernize flight procedures in ways that could affect flight paths and noise exposure at airports such as Sea-Tac.

In October 2012, the Federal Aviation Administration (FAA) approved new GPS-based arrival flight paths into Seattle-Tacoma International Airport (Sea-Tac) under the 'Greener Skies Over Seattle' initiative. The new procedures, developed in partnership with Alaska Airlines, Boeing, and the Port of Seattle, use satellite navigation technology to guide arriving aircraft on more precise, fuel-efficient descent paths from the northwest and southwest. The FAA concluded that the changes would not cause significant environmental harm, issuing a Finding of No Significant Impact (FONSI) alongside its formal approval.
