TagAviation Emissions(100)

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.

Promotional graphic from U.S. Representative Adam Smith (Washington's 9th District) highlighting provisions in the 2025 Federal Aviation Reauthorization bill focused on alternative aviation fuel investments, including study of electric and hydrogen-powered aircraft integration, expanded alternative fuel research, and coordinated strategies for new aviation fuel systems under the Airport Improvement Program.

Promotional graphic from U.S. Representative Adam Smith (Washington's 9th District) highlighting 2025 Federal Aviation Reauthorization provisions focused on sustainability, including research into alternative aviation fuels (hydrogen and electric power) and improved energy efficiency at airports. The graphic is branded with Smith's official congressional logo and framed under the theme 'Protecting Airport Communities.'

Long exposure photograph showing curved light trails of aircraft in flight against a dark night sky above a city horizon. The image captures the flight paths of multiple aircraft with their navigation lights creating streaking patterns through the darkness.

An F-35 Lightning II stealth multirole fighter aircraft is photographed from below during flight, with visible wingtip vortices — condensation trails formed by low-pressure airflow at the wingtips. A caption label in the image explicitly identifies the aerodynamic phenomenon as 'Wingtip vortices.'

An infographic published by 350 Seattle detailing aviation's environmental impact, including projected emissions growth to +1200% by 2050, environmental justice concerns around Sea-Tac Airport, and the claim that commercial aviation produced 918 million metric tons of CO2 in 2018. The infographic includes a map showing the 3km and 10km pollution radius around Sea-Tac Airport and calls for a reduction in aviation to meet climate goals.

Logo for 'Fly Net Zero,' an aviation industry initiative promoting net-zero carbon emissions. The logo features bold blue text alongside a circular globe-like graphic rendered in blue tones.

A pie chart titled 'Our strategy towards net zero' outlines a combination of approaches to achieve net zero by 2050: 65% Sustainable Aviation Fuel (SAF), 19% Offsets and carbon capture, 13% New technology, electric and hydrogen, and 3% Infrastructure and operational efficiencies. No organizational logo or authorship is clearly visible in this cropped image.
