    Delta Air Lines Sustainability Overview

    Delta Air Lines has committed to reaching net zero carbon emissions by 2050, with shorter-term goals including using 10% Sustainable Aviation Fuel (SAF) by 2030 and setting science-based emissions targets aligned with aviation industry guidance. To reduce its environmental footprint, Delta has retired over 200 older aircraft and replaced them with newer, more fuel-efficient models that burn 20-25% less fuel. The airline's emissions reduction strategy relies on three main levers: fleet renewal, operational improvements, and increased use of SAF.

    StART Meeting 11 Slide: Commitment to SBTi and Net Zero by 2050 (2022-10-26)

    A Zoom Webinar screenshot showing a PowerPoint slide titled 'Commitment to SBTi and Net Zero by 2050,' presented during StART (Sea-Tac Airport Roundtable) Meeting 11 on 2022-10-26. The slide outlines short-term (10% SAF by 2030), medium-term (science-based targets aligned with aviation guidance), and long-term (net zero 2050 across the entire value chain) emissions goals, with a chart showing projected absolute emissions reductions via Fleet Renewal, Operational Improvements, and SAF. Participant Stephanie Zhu is visible in the video thumbnail.

    It’s About More Than Just CO₂: Aviation Must Reduce Its Total Impact on Climate

    Aviation's climate impact is roughly three times greater than its CO2 emissions alone, because burning jet fuel at altitude also produces contrails, induced cloudiness, and NOx byproducts that add significant additional warming. A 2020 study by 21 leading scientists found that in 2018, aviation accounted for approximately 5.9% of all human-caused global heating when these non-CO2 effects are included. The fact sheet calls for immediate action including contrail-avoidance flight routing, cleaner fuels, stricter emissions regulations, and reduced air traffic overall.

  • ultra-fine-particles

    Infographic comparing sizes of airborne particulate matter relative to a human hair (50 micrometres in diameter): ultrafine particles (<100 nanometers), fine particles (<2.5 micrometres), and coarse fine particles (<10 micrometres). The diagram uses scaled spheres to visually illustrate how these pollution particles relate in size to a strand of human hair.

  • Effects of Ultrafine Particles

    Infographic from Daily News, illustrated by staff artist Warren Huskey, explaining how atmospheric ultrafine particles (diameter less than 0.1 micrometers) enter the human body and cause adverse health effects including possible brain cancer, heart attacks, and liver invasion. It details particle size comparisons (PM10, PM2.5, and ultrafines) relative to human hair thickness of 60 microns.

  • Lung Cancer

    A detailed medical infographic titled 'Lung Cancer' covering risk factors, types (small cell and non-small cell), stages, early detection methods, and treatments. Includes sections on environmental/external risk factors such as asbestos, beryllium, radon, and Agent Orange, with particular relevance to veterans.

    King County Communitywide Geographic Greenhouse Gas Emissions: Puget Sound Regional Emissions Analysis

    This August 2022 report by Cascadia Consulting Group analyzes greenhouse gas emissions across King County, Washington, examining where emissions come from, what is driving trends over time, and how the county can meet its climate goals. The report covers sectors including transportation, electricity, natural gas, solid waste, and land use, tracking data from multiple inventory years and comparing per-capita emissions across jurisdictions. It also models future emissions scenarios to assess the impact of federal, state, and regional policies on reaching reduction targets through 2050.

    Making Net-Zero Aviation Possible: An Industry-Backed, 1.5°C-Aligned Transition Strategy

    This July 2022 report from the Mission Possible Partnership outlines a global strategy for reducing aviation's greenhouse gas emissions to net zero by 2050, in line with the 1.5°C climate target. It identifies key milestones, technologies, and investments needed across the aviation value chain, including sustainable aviation fuels and new propulsion systems. The strategy is intended to guide airlines, policymakers, and financial institutions in taking coordinated action this decade.

    Recovering from COVID-19: The airline perspective

    A February 2021 presentation by Airlines for America outlines how COVID-19 devastated the airline industry, with worldwide passenger traffic dropping 66% and U.S. carrier revenues falling 61.5% year-over-year. Despite these financial losses, airlines remained committed to environmental progress, including accelerating the retirement of older, less fuel-efficient aircraft in favor of newer, cleaner models. The presentation also highlights the role of Sustainable Aviation Fuel (SAF) and aviation's broader responsibility in achieving a sustainable future.
