A 2021 seminar by DLR researcher Christiane Voigt examines how aviation contributes to climate change through CO2 emissions, contrail cirrus clouds, and NOx gases, with contrail cirrus identified as the largest single warming factor at 57.4 mW m⁻². The presentation outlines strategies to reduce aviation's climate footprint, including the use of alternative fuels, lean combustion technology, and contrail avoidance routing. Findings draw on data from recent aircraft measurement campaigns and observed emission reductions during the 2020 COVID-19 lockdown.Open full document
Notes
A seminar presentation by Christiane Voigt of DLR German Aerospace Center at the Aviation Noise & Emissions Symposium. The presentation covers global effective radiative forcing from aviation, including contributions from contrail cirrus, CO2, and NOx emissions. Topics include climate impact mitigation strategies such as alternative fuels, lean combustion, reduced emissions during COVID-19 lockdown, and contrail avoidance.
