When tribal business required him to travel, Dana took the train to Washington, D.C., which he jokes elicited some complaints from the other tribal members who went with him. "I thought, 'I think that's where we need to be as a world, essential flights only.'" "That may have been the first time we used the term, 'essential flights only,'" Dana said.

And I've got a bottle of gasoline, or I have a bottle of water. "For me, that's like, there's a fire," said Barry Dana, a former chief of the Penobscot Nation.

Scientists have issued dire warnings year after year: The world must take drastic steps to reduce its reliance on fossil fuels to keep global warming to 1.5 degrees Celsius. "It's a mindset shift, and I feel liberated and happy, because knowing about the climate emergency and the zero time we have left," he said. Interest appears to have ticked up again, as the site has a total of 469 people who have taken the pledge so far this year.įor Castrigano, he stopped flying four years ago. Three years ago, 444 Americans signed the petition, and the numbers have dipped since then as air travel began to rebound during the pandemic. Thousands have signed pledges in the UK and Sweden. The group is the American chapter of a global non-profit that's urging people to give up flying. "If you're rich enough to fly in the first place, then you're only part of the 20% of humans on Earth who have ever been on a plane," said Dan Castrigano of Vermont, a Flight Free USA organizer. Scientists say the carbon emissions from driving long distances are often comparable to those produced from some flights. But they say air travel is the single activity that produces the most carbon emissions per person at any one time.Īir travel accounts for nearly 4% of the world's carbon emissions, and frequent fliers, who make up only 1% of the world population, are responsible for half of those emissions, according to studies from multiple studies and the International Council on Clean Transportation. Sullivan, who helped found Freeport's climate action group a few years ago, said she never completely swore off flying. "Every time the opportunity to fly arrived at my doorstep, I thought there's no reason for me to fly," she said. Sullivan said she's excited about the adventure, but, she admits, the decision to go has weighed on her.
Nearly three billion people each emit less greenhouse gas than those flights’ 2.9 metric tons in one year.
The flights from Newark to Athens and back, alone, are the equivalent of carpooling for nearly three years or being a vegetarian for more than five years, according to FlightFree USA. That's twice the annual per person limit that scientists say is needed to contain global warming. The exact carbon impact of flights will vary depending on the time of day, season and type of aircraft, among other things.Īltogether, Sullivan's flights will emit about 3.2 metric tons of carbon per passenger, according to a calculator from the group Flight Free USA.
