US Treasury Secretary Janet Yellen has released details of a tax hike proposal that would replace subsidies for fossil fuel companies with incentives for production of clean energy in President Joe Biden's infrastructure plan.
Linked to the $2.3 trillion infrastructure package, it is part of wider plan that includes boosting the corporate income tax rate from 21% to 28%.
A Treasury Department office estimated that eliminating subsidies for fossil fuel companies would boost government tax receipts by more than $35 billion in the coming decade.
The "Made In America" tax plan did not specify which tax breaks for fossil fuel companies would be targeted.
It said the subsidies undermine long-term energy independence and the fight against climate change and harm air and water quality in US communities, especially communities of colour.
One of the top fossil fuel breaks is called intangible drilling costs, which allows producers to deduct most costs from drilling new wells. The Joint Committee on Taxation has estimated that ditching it could generate $13 billion over 10 years.
The Biden tax plan would advance clean electricity production by providing a 10-year extension of the production tax credit and investment tax credit for clean energy generation, such as wind and solar power, and energy storage such as advanced batteries.
It also creates a tax incentive for long-distance transmission lines to ease movement of electricity from clean energy generators.
The plan would restore a tax on polluters to pay for Environmental Protection Agency costs associated with Superfund toxic waste sites, addressing harm caused by fossil fuel production.
Unwinding tax breaks on fossil fuel companies could face opposition from Biden's fellow Democrats in the US Congress from energy-producing states.
Greenpeace, an environmental group, said the plan does not go far enough, citing a study calculating that US fossil fuel companies get $62 billion a year in implicit subsidies for not having to pay for damage their products do to the climate and human health.
The plan is expected to face resistance from fossil fuel lobbyists. The American Petroleum Institute said last week that getting rid of the breaks would amount to new taxes on oil and gas drillers.
"Targeting specific industries with new taxes would only undermine the nation's economic recovery and jeopardize good-paying jobs, including union jobs," the API said last week in response to Biden's infrastructure plan.
The Treasury Department confirmed that the Biden plan includes a blender's tax credit for sustainable aviation fuel, a top priority of USairlines, which Treasury said would enable "the decarbonisation of a key portion of the US transportation sector."
The plan also "proposes incentives to encourage people to switch to electric vehicles and efficient electric appliances." The Treasury has not specified how it would revise or expand existing credits.
A top airline industry group praised the plan's inclusion of the blender's credit.
Nancy Young, vice president of environmental affairs at Airlines for America, said a credit of up to $2 a gallon would help build the market for sustainable aviation fuel, providing an incentive for companies to integrate more renewable fuel into the supply.
