Using sustainable aviation fuels could reduce emissions by up to 80%, scientists find::A team of scientists have completed tests to quantify the emissions from the combustion of sustainable aviation fuels, revealing a profound reduction when compared to regular jet fuel.Researchers from the National Centre for Atmospheric Science (NCAS), including those from The University of Manchester, compared standard jet fuels with several di…
The use of biomass rather than fossil fuels, if it can be scaled up is carbon neutral. The biomass grows from CO2 in the atmosphere.
Yes this will take about 60% of our crop land to completely replace fossil fuels (including cars), but this is completely doable if we reduce grain production for livestock. Source: https://esa.org/biofuels/presentations/Auyeung_poster.pdf
More to the point, it’s much more easily doable if we quit wasting hydrocarbon fuels on ground transportation by making our cities walkable and moving longer-range travel to electrified rail.
