General Motors to pay nearly $146 million for cars that violated emissions regulations

General Motors has reached an agreement with the Environmental Protection Agency and the Transportation Department to resolve excess emissions stemming from nearly 6 million of its vehicles — and the company has agreed to pay a penalty of nearly $146 million.

The penalty is a result of an EPA investigation that identified excess carbon emissions from GM vehicles, violating federal regulations. Tests done by both GM and the EPA showed that the company’s vehicles were emitting an average of 10% higher CO2 levels than previous reports claimed.
