The Chamber claimed in a lawsuit that the Obama administration improperly created a patchwork of emissions standards by allowing California to impose its own rules. The Chamber, joined by NADA, challenged the waiver granted to California by the Environmental Protection Agency (EPA). But, the federal appeals court stated, that wasn't enough:
The waiver from Clean Air Act standards, issued back in 2009, pertains to emissions for vehicles manufactured between 2012 and 2016. Thirteen other states, along with the District of Columbia, have agreed to adopt California's more stringent standards. Automakers argue that this will force them to alter vehicles delivered to California and other states that have adopted the same emissions guidelines. NADA warns that dealerships may be unable to obtain certain vehicles because they don't comply with regulations.Because the Chamber has not identified a single member who was or would be injured by EPA's waiver decision, it lacks standing to raise this challenge.
