Airlines and scientists are coming to a consensus that the water vapor trails created by airplanes at high altitudes may play a big role in global warming....
set a 2050 date to cut their emissions footprint entirely. To date, most of the emissions reductions that airlines have been able to achieve have been through using more fuel-efficient engines while waiting for a sustainable aviation fuel industry using recycled oils to emerge and research on hydrogen and electric engines.“The science around contrails has become more clear in just the last few years,” said.
The worst contrails happen at night when the earth is naturally cooling without sunlight but manmade clouds at that critical altitude can block heat from escaping, Chen said. Pilots and airlines know how to avoid making contrails, but there are other factors that go into planning a flight, said. Airlines have to factor weather, potential turbulence and speed, she said. Then they don’t want to make a flight plan based on avoiding contrails when it would burn significantly more fuel.
“From an operational perspective, we think we know what we can do to mitigate the impact, but we want to see the modeling before we build a plan around it,” she said. ”It’s really difficult to weigh the impact of radiative forcing versus carbon dioxide from fuel burn.”
