The European Union is considering the use quotas to force airlines to use more sustainable aviation fuel as it seeks to reduce carbon emissions.
The European Commission said that flights within Europe had climbed every year from 2013-2019 and the sector was off track for the EU’s goal to become climate neutral by 2050.
However the COVID-19 pandemic has slashed CO2 emissions from air travel as countries locked down and severe restrictions were put in place.
The Commission plans to push airlines towards using lower-carbon fuels - such as liquid advanced biofuels and fuels produced by renewable electricity - instead of fossil kerosene.
The Commission's options include setting quotas for airlines to use a certain share of sustainable fuels and an obligation for the fuel industry to produce a minimum share of them.
Other options include a European trading system for fuel carbon credits, European tenders for sustainable fuels production, or a new “green airlines” accreditation scheme.
