Arlington, Virginia – The Association of International Automobile Manufacturers (AIAM) has dropped its lawsuits challenging California’s vehicle greenhouse gas (GHG) emissions standards, following the creation of a national U.S. standard that California has agreed to follow.

The legal challenges, mounted by the AIAM and other auto industry parties, have been ongoing for five years. “The litigation was initiated to prevent the creation of a disjointed patchwork of federal and state greenhouse gas and fuel economy regulations across the country,” said AIAM president and CEO Michael J. Stanton. “We are voluntarily dismissing these lawsuits because the auto industry has achieved its goal.”

On April 1, 2010, the Obama Administration issued its final regulations establishing a unified national program to substantially reduce GHG emissions and improve fuel economy from light-duty vehicles for model years 2012-2016. Canada has adopted the same standards concurrent with the timing of the U.S. regulations.

“AIAM believes this type of cooperative and constructive engagement results in better public policy than protracted and adversarial litigation,” Stanton said. “We look forward to working closely with all stakeholders to develop a similar program post-2016 to ensure that the auto industry will continue to play a key role in addressing climate change.”

The AIAM is a trade association representing Aston Martin, Ferrari, Honda, Hyundai, Isuzu, Kia, Mahindra, Maserati, McLaren Automotive, Mitsubishi, Nissan, Peugeot, Subaru, Suzuki and Toyota.
