New technologies, including one fuel extracted from the atmosphere itself, could make flying more sustainable. But the challenges are many and the timeline is uncertain.
A Big Climate Problem With Few Easy Solutions: Planes The airline industry might not be able to reduce greenhouse gas emissions for decades because most solutions are not yet viable. A recently announced United Airlines deal will result in the airline’s buying about 3.4 million gallons of sustainable fuel this year.Credit.Sebastián Hidalgo for The New York Times May 28, 2021, 5:00 a.m. ET The worst of the pandemic may be over for airlines, but the industry faces another looming crisis: an accounting over its contribution to climate change.
