WASHINGTON (AP) — Environmental groups are suing federal regulators over long-sought pollution standards for airliners and cargo planes.

The Center for Biological Diversity and Friends of the Earth filed a lawsuit Tuesday in U.S. District Court in Washington. The groups allege the Environmental Protection Agency has unreasonably delayed for years using the Clean Air Act to enforce limits on heat-trapping greenhouse gas emissions from aircraft.

A United Nations panel in February proposed requiring an average 4 percent reduction in fuel consumption for new aircraft by 2028. Environmentalists have criticized that proposed reduction as too modest to significantly curb climate change. They are pushing EPA to enact more stringent standards.

Aviation accounts for about 5 percent of global carbon emissions, with U.S.-owned airliners emitting about 30 percent of all aircraft pollution worldwide.
