Bill Gates Says Aviation Is One of the Hardest Sectors to Decarbonize Amid Skyrocketing Fuel Costs—Here's His Solution
Philanthropist and Microsoft Corp. (NASDAQ: MSFT ) co-founder Bill Gates says aviation remains one of the hardest sectors to decarbonize, but avoiding warming contrails could provide a relatively inexpensive way to reduce the industry’s climate impact. Bill Gates Says Contrails Make the Planet Hotter In a thread on the social media platform X, Gates said that aircraft contributed to climate change by carbon emissions from burning fuel and by Condensation Trails, or contrails. “Those are the lines you’ll sometimes see forming behind a plane as it flies, and there are a lot of misconceptions about them,” he said, referring to people calling the lines “chemtrails” that emit “toxic chemicals,” but the lines were nothing more than clouds, Gates said. Planes contribute to climate change in two ways: they emit carbon when they burn fuel, and they can create contrails. Those are the lines you’ll sometimes see forming behind a plane as it flies, and there are a lot of misconceptions about them.

Some people refer to them as… — Bill Gates (@BillGates) October 8, 2026 “Persistent contrails are responsible for about half of the temperature increase caused by aviation,” Gates said. The philanthropist added that the Earth could “eliminate up to two percent of all global warming” if contrails did not exist. Researchers are looking for ways to stop them from forming — not because they’re poisonous, but because, in the right conditions, they make the planet hotter. Persistent contrails are responsible for about half of the temperature increase caused by aviation.

“Contrails reflect sunlight entering our atmosphere and absorb heat before it can leave,” Gates said, which may lead to temperatures rising at night as contrails trap heat. “To avoid the majority of warming contrail regions, we would need to adjust the routes of just five percent of flights globally,” Gates said, adding that flights could fly slightly above or below the contrail zones.

World’s Largest Battery-Electric Aircraft Takes Flight Amid the contrails idea, aerospace manufacturer Heart Aerospace, in early September, demonstrated that its X1 battery-electric aircraft flew for 27 minutes using $5 worth of electricity in August under a special Federal Aviation Administration (FAA) airworthiness certificate. Space Exploration Technologies Corp. (NASDAQ: SPCX ) and Tesla Inc. (NASDAQ: TSLA ) CEO Elon Musk hailed the flight.
