Korean automakers Hyundai Motor and Kia Motors have agreed to a roughly $350 million settlement with the federal government for overstating vehicle fuel-economy standards — a deal that some analysts say indicates the Obama administration's commitment to enforcing regulations aimed at addressing climate change. The settlement, announced Monday by the Department of Justice (DOJ) and the Environmental Protection Agency (EPA), includes a $100 million civil penalty, the largest ever for a violation of the Clean Air Act. In addition to the fine, the two companies will forfeit greenhouse gas emissions credits worth in excess of $200 million and spend another approximately $50 million on measures to prevent future violations. "Today's action sends a clear signal to the industry that the EPA is serious about assuring compliance with greenhouse gas standards and committed to tough enforcement when necessary," an EPA representative told VICE News.
