At 3 mins 38 seconds I confused the horizontal with the vertical axis. Sorry about that! What can we do to reduce the carbon footprint of air travel? In this video we look at battery powered planes, hydrogen powered ones, bio fuel, and synthetic kerosene. Data about airplane emissions come from Our World in Data https://ourworldindata.org/co2-emissions-from-aviation The figure for the increase of airplane efficiency is from this report: https://theicct.org/sites/default/files/publications/Aircraft-fuel-burn-trends-sept2020.pdf The figure for the energy per volume and energy per mass values for different fuels is from this paper: https://www.mh-aerotools.de/company/paper_14/MP-AVT-209-09.pdf Data for the cost of bio jet-fuel is here: https://www.irena.org/-/media/Files/IRENA/Agency/Publication/2021/Jul/IRENA_Reaching_Zero_Biojet_Fuels_2021.pdf The paper about the increased efficiency of gene-edited microalgae is this: https://www.nature.com/articles/nbt.3865 The number for the carbon-dioxide emissions of synthetic jet fuel comes from here: https://www.transportenvironment.org/wp-content/uploads/2021/02/FAQ-e-kerosene-1.pdf Numbers for the cost of synthetic jet fuel are from here: https://theicct.org/wp-content/uploads/2022/02/fuels-us-europe-current-future-cost-ekerosene-us-europe-mar22.pdf
