Why is the aviation sector so hard to decarbonize?
The transportation sector generates 15% of all global CO2,eq emissions and, currently, aviation accounts for around 2% every year. However, this does not give the full impact of aviation on the climate. Aviation accounts for 3.5% of global effective radiative forcing, i.e. 3.5% of global warming.
To overcome the industry's overwhelming reliance on conventional jet fuel, both alternative fuels and revolutionary aircraft designs are necessary. Additionally, to further help minimize the sector's warming impact on the planet, technological innovation should extend beyond the aircraft itself, encompass airport operations, and flight path optimization.
To reach net zero by 2050, we require a holistic transformation of the aviation sector that considers non-CO2 effects.
