General Motors will pay a $145.8 million penalty after a US government probe found excess emissions from approximately 5.9 million GM vehicles, Reuters reports.
In addition, the automaker will forfeit credits worth hundreds of millions of dollars.
Auto safety regulator, the National Highway Traffic Safety Administration (NHTSA) said GM will pay a $145.8 million penalty for fuel economy compliance issues.
The firm will also cancel more than 30.6 million fuel economy credits for the 2008-2010 model years to resolve the issues identified by Environmental Protection Agency’s (EPA) light-duty vehicle in-use testing program.
In a separate statement, the EPA said GM has agreed to give up approximately 50 million metric tons in carbon allowances.
It comes after the multi-year investigation found 2012-2018 model year vehicles were emitting more than 10% higher carbon dioxide on average than GM’s initial compliance reports claimed, according to Reuters.
