The lawsuits, announced yesterday, allege that numerous employees and executives at Volkswagen knew that diesel vehicles had been equipped with software allowing them to cheat emissions testing, and that after regulators began investigating several employees tried to cover it up by eliminating data about the software.
"The allegations against Volkswagen, Audi and Porsche reveal a culture of deeply-rooted corporate arrogance, combined with a conscious disregard for the rule of law or the protection of public health and the environment," said New York Attorney General Eric Schneiderman.
In a statement, Volkswagen said it is already in talks with authorities regarding "a comprehensive national resolution of all remaining environmental issues arising from the diesel matter." The company also noted that it has agreed to buy back or modify affected vehicles, create a USD 2.7 billion environmental trust and invest USD 2 billion on infrastructure for zero-emission vehicles.

"It is regrettable that some states have decided to sue for environmental claims now, notwithstanding their prior support of this ongoing federal-state collaborative process."
The legal action seeks "substantial penalties" that would be based on a calculation of the duration of the alleged violations.
While news of the rigged emissions tests first erupted a year ago, the new legal action makes several new allegations most notably about the involvement of Volkswagen engineers and executives. The suit alleges that Volkswagen submitted false emissions data to regulators and sought to eliminate evidence when an investigation began.
