    By ED DAVEY The Associated Press A consumer class action lawsuit filed Tuesday claims Delta Air Lines inaccurately billed itself as the world’s “first carbon-neutral airline” and should pay damages.

    Berrin v. Delta Air Lines: Class Action Complaint

    A class action lawsuit filed in May 2023 against Delta Air Lines alleges that the airline falsely marketed itself as the 'world's first carbon-neutral airline' since March 2020. The complaint argues that Delta's reliance on voluntary carbon offsets did not actually eliminate its net carbon emissions, as those offsets suffer from inaccurate accounting, non-additional effects, and impermanent results. Plaintiff Mayanna Berrin seeks to represent a nationwide class of Delta ticket purchasers who allegedly paid premium prices based on these misleading environmental claims.

    Contrails and their impact on climate

    This Delta Air Lines presentation from the 2023 Aviation Noise & Emissions Symposium explains what contrails are, how they form, and why they matter for the climate. Contrails are line-shaped clouds created by aircraft engine exhaust or air pressure changes, forming through a rapid process in which exhaust particles become water droplets and then ice crystals within seconds. The presentation explores how to measure contrails' environmental impact and what solutions, including route adjustments, Delta is pursuing to reduce it.

    Class Action Complaint: Codoni and Geer v. Port Of Seattle, Alaska Air Group, and Delta Air Lines, Inc.

    A class action lawsuit filed in King County Superior Court by plaintiffs Cindy Codoni and Michelle Geer against the Port of Seattle, Alaska Air Group, and Delta Air Lines alleges that aircraft operations at Seattle-Tacoma International Airport have contaminated the surrounding air and soil with dangerous pollutants, including particulate matter, hazardous gases, and toxic heavy metals. Residents living beneath flight paths below 3,000 feet claim increased health risks and property damage as a result of the defendants' ongoing activities. The suit seeks medical monitoring, property decontamination, and other relief on behalf of all similarly situated homeowners, renters, and residents in the affected area.

Read This!

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
