The airline industry’s plan to ease its impact on global warming hinges on fuels made from vegetable oil, corn and household garbage.
The aviation industry is being pushed to act this week by delegates from 190 nations, who are debating a United Nations accord in Montreal that would cap emissions from international flights.
With electric planes still experimental, airlines and aerospace companies say biofuels offer the best opportunity.
Advocates for renewable jet fuel say the industry will develop after the UN accord takes effect.
“Airlines are stepping up and creating demand,’’ said Sophia Mendelsohn, JetBlue’s head of sustainability. “It is hard for me to envision a long-term situation where the biofuel industry does not mature and develop.”
