Cathay Pacific is going to use aviation biofuels made from landfill rubbish on some of its long haul flights.

From 2019, the Hong Kong carrier’s flights from the US – where Cathay has already invested in Fulcrum BioEnergy –  to Hong Kong, will use a combination of conventional fuel and biofuel.

“Aviation biofuels will play a key role for Cathay and the aviation industry’s quest for lower emissions,” the airline’s biofuel manager, Jeff Ovens, told the South China Morning Post. “We are on the cusp of large-scale production of low-carbon jet fuel and are eager to use it.”

Cathay aims to cut emissions by 80% on these flights.
