THE FACTS: That’s a giant step that will be highly difficult, if not impossible, to achieve.
Only 2.4 million gallons of sustainable aviation fuel, or SAF, were produced in the United States in 2019, according to the Environmental Protection Agency. In contrast, airlines burned 21.5 billion gallons of regular fuel that year. That means just over 0.01% of the nation’s supply currently comes from sustainable fuel.
The airline industry says bridging the gap will require bold steps including grants and tax credits for producers, government support for research, and more. Biden is seeking a SAF tax credit as part of a $3.5 trillion spending bill being pushed in Congress by Democrats, but its outcome remains uncertain. Even with that money, it’s not clear all those things would be enough to meet the administration’s ambitious goals, according to aviation experts.
“Aspirational goals like this don’t move markets,” says Dan Rutherford, who oversees aviation research at the International Council on Clean Transportation, an environmental group based in Washington.
Without a government mandate or “very strong incentives,” Rutherford says, “I doubt that much SAF will be generated.” He notes that the International Air Transport Association, a global trade group for airlines, had a voluntary goal of 10% sustainable fuel by 2017 and the federal government had a target of 1 billion gallons per year by 2018, “and neither came anywhere close.”
Liz Jones, a climate-law attorney at the Center for Biological Diversity, says the administration plan “largely relies on biofuels aspirations that simply aren’t based on reality.”
Airlines have been announcing promises to become carbon neutral around the middle of the century, and some have invested in sustainable fuel as they defend against criticism over aviation’s role in climate change. Airplanes produce only around 3% of the world’s heat-trapping emissions, but their share is growing rapidly.
Jones says, however, that nothing in the administration’s plan would force airlines to live up to their promises.
“And even the best-case scenario doesn’t cut climate pollution fast enough,” she says. “The Biden EPA needs to set strong airplane emissions standards now, not get mired in the myth of sustainable airline fuels.”
The White House and airline trade groups are counting on tax credits to produce three billion gallons a year by 2030. Airline trade groups are pushing Congress to enact a tax credit of $1.50 to $2 per gallon, depending on how much the fuel reduces greenhouse gas emissions when burned.
Airlines for America, a trade group for the biggest U.S. airlines, had previously set a goal of producing 2 billion gallons of sustainable fuel in 2030. This week, the group agreed to back the White House goals.
The airline group’s president, Nicholas Calio, said the airlines “are proud of our record on climate change, but we know the climate change challenge has only continued to intensify,” and so it raised its goal for sustainable fuel.
Airlines are also placing orders and making investments in startups that are designing aircraft powered by electricity or hydrogen. Some of the manufacturers aim to have small electric planes of up to 19 seats in service by the end of the decade.
“We want to operate aircraft that are very good for the environment in the long run,” Andrew Nocella, the chief commercial officer of United Airlines, said this week. “How they come to be and when they come to be is still a little bit TBD (to be determined).”
