Cathay Pacific on Monday said it has set a new target to improve its carbon intensity, as part of efforts to achieve net zero carbon emissions by 2050.

The airline said by 2030, it aims to improve its carbon intensity by 12 percent from the 2019 level.

It said the goal is to reduce carbon emissions from jet fuel use by more than 10 percent, to 670 grammes of carbon dioxide per revenue tonne kilometre.

In the coming years, the airline will get more than 70 new aircraft which will be up to 25 percent more fuel efficient than older planes, Cathay said.

CEO Ronald Lam said the new target will help the company achieve long-term goals.

"Despite being a major airline with one of the best carbon intensity performances in the world, we are determined to improve our climate performance even further via accelerating the use of sustainable aviation fuel, modernising our fleet and driving operational improvements," he said in a statement.
