June 18 (Reuters) - The top U.S. oil and corn industry

lobby groups said on Tuesday they were suing the administration

of President Joe Biden over its plan to slash planet-warming

emissions from heavy-duty vehicles, arguing the regulations will

cause economic harm.

The U.S. Environmental Protection Agency this spring

finalized new rules for models of semi-trucks, buses and other

heavy-duty vehicles released from 2027 to 2032 in a bid to cut 1

billion tons of greenhouse gas emissions through 2055.

Heavy duty vehicles are big contributors to climate change,

accounting for around 7% of national emissions, according to EPA

data, and the standards formed a major part of Biden's broader

plan to fight global warming.

"The EPA is forcing a switch to technology that simply does

not presently exist for these kinds of vehicles - and even if it

were someday possible, it will almost certainly have

consequences for your average American," said Ryan Meyers,

senior vice president and general counsel for the American

Petroleum Institute (API).

The API is the top U.S. oil and gas lobby group and includes

Exxon Mobil ( XOM ) as a member.

The National Corn Growers Association, the American Farm

Bureau Federation and the Owner-Operator Independent Drivers

Association said they had joined Tuesday's suit, arguing in

favor of other methods to fight climate change like biofuels.

"EPA has tried to impose a one-size-fits-all approach to

addressing climate change by prioritizing electric vehicles over

other climate remedies like corn ethanol," said National Corn

Growers Association President Harold Wolle.

The EPA did not immediately respond to a request for

comment.

The API had already filed a federal lawsuit earlier this

month seeking to block the Biden administration's efforts to

reduce emissions from cars and light trucks. Under those rules,

the administration projects up to 56% of all car sales will be

electric between 2030 and 2032.
