The government must hold the aviation sector accountable for its proposed cuts to emissions, MPs on the Environmental Audit Committee (EAC) have said.

In the Jet Zero Strategy, which was published in 2022, the government proposed various technological measures, such as increasing fuel efficiency and the adoption of sustainable aviation fuels. The model assumes that fuel efficiencies will improve by 2% each year, in line with evidence from the aviation sector.

But the EAC has urged the government to hold the aviation industry accountable for the reductions should they not be met.

Last year, a survey of aviation experts found that the majority are not convinced that the sector will become carbon neutral by the stated 2050 goal.

Aviation, which accounts for approximately 3% of total CO2 emissions worldwide, is considered a hard-to-abate sector because of a lack of technologically mature alternatives to traditional jet-fuelled engines such as electric or hydrogen-fuelled aircraft.
