(Reuters) - A group of 22 states led by California and five cities are backing the U.S. Environmental Protection Agency's new tailpipe emissions rules after 25 Republican-led states sued the agency last week claiming the new regulations were unworkable and unlawful.
The lawsuit filed Thursday in the U.S. Court of Appeals for the District of Columbia challenges the 2027-2032 model year EPA vehicle emissions rules that aim to cut fleetwide tailpipe emissions for cars and light trucks by nearly 50% over 2026 levels in 2032.
