Cambridge University has published a report outlining a five-year roadmap to help the aviation sector achieve net zero by 2050.

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, as well as the low scale-up of sustainable aviation fuel (SAF) production.

Despite industry pledges and government action, such as the UK government’s sustainable aviation fuel (SAF) mandate, the Aviation Impact Accelerator (AIA) argues that the aviation sector still remains significantly off-course in its efforts to achieve net-zero emissions by 2050.

The AIA, a project led by the University of Cambridge and hosted by the university’s Whittle Laboratory and the Cambridge Institute for Sustainability Leadership (CISL), has published a report that outlines an ambitious five-year plan to get the sector back on course for net zero by 2050.
