Technology for change

The use of alternative fuels could be one way for the aviation sector to reduce its emissions. A new study of fuel use in domestic flights in Norway shows some mitigation potential for alternative fuels, but warns that these alternatives are neither emission-free nor climate-neutral.

The aviation industry’s response to climate change relies mainly on cleaner fuels and carbon offsetting. Government and industry must experiment with other approaches to bring the climate impact of aviation closer to zero, argues researchers in a Nature commentary.
