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.
By Theo Leggett Business correspondent, BBC News In a windswept corner of a military site on Salisbury Plain a small aircraft jet engine is undergoing tests that could one day lead to huge changes within the aviation industry. The engine itself is almost completely conventional. It is a Rolls-Royce AE-2100A gas turbine, a design used

A 2022 report by InfluenceMap examines how aviation industry interests shape climate policy at the UN's International Civil Aviation Organization (ICAO), finding that 31% of delegates at recent climate negotiations represented industry. The report highlights that ICAO's limited transparency practices—including non-disclosure agreements, restricted media access, and undisclosed delegate affiliations—allow corporate influence to steer global aviation emissions policy. As a result, ICAO has prioritized carbon offsetting over direct emissions reductions, with global aviation CO2 emissions projected to grow by 190–277% between 2015 and 2050.
Fly Net Zero is the commitment of airlines to achieve net zero carbon by 2050. At the 77th IATA Annual General Meeting in Boston, USA, on 4 October 2021, a resolution was passed by IATA member airlines committing them to achieving net-zero carbon emissions from their operations by 2050. This pledge brings air transport
