Cedar Rapids Gazette: The Iowa Department of Transportation is allocating more than $3 million in federal settlement funds to help state schools and communities replace diesel vehicles with more environmentally friendly buses. As part of a 2016 federal court settlement, in which Volkswagen officials admitted to programming diesel vehicles to cheat emissions standards, the automaker agreed to pay $2.8 billion to states to reduce diesel pollution. For Iowa, that means $3.15 million in grant opportunities for eligible private organizations, public transit system operators, cities, counties and schools looking to update their diesel fleets and equipment.
