The D.C. Circuit ruled today that plaintiffs lacked standing to challenge EPA and NHTSA's standards for greenhouse gas emissions from cars and trucks. The ruling means that the case is dismissed, and the standards stay in place.
The case, Delta Construction v. EPA, tests a joint effort by the EPA and NHTSA to regulate greenhouse gas emissions from automobiles and trucks. The agencies issued coordinated rules, one set of rules for cars and, later, one set for trucks. (The D.C. Circuit previously upheld the car rules, and the Supreme Court denied review.)
The plaintiffs--business, associations, and individuals in California, and Plant Oil Powered Diesel (or POP Diesel), a company that promotes the use of vegetable oil in place of traditional diesel fuel--sued, arguing that the regulations were arbitrary and capricious in violation of the Administrative Procedures Act. The California plaintiffs challenged the EPA rules only; POP Diesel challenged both the EPA and NHTSA rules. The California plaintiffs argued that the regs jacked up the price of cars and trucks in the state; POP Diesel argued that the truck rule makes its product economically unfeasible.
The court held that the California plaintiffs lacked standing, because they couldn't show causation and redressability. That's because even if they won on the merits--and the court struck the EPA rules--the NHTSA rules would still drive the prices of their vehicles up. In other words, because both agencies' sets of rules did the same thing, defeating one wouldn't solve their alleged problem.
As to POP Diesel, the court said that it didn't fall within the zone of interests protected by the portion of the Clean Air Act governing emissions standards for motor vehicles. The court said that economic interests, like POP Diesel's, without more, aren't within the congressional goals of the Act, and that POP Diesel's green approach alone doesn't put it within the Act's zone of interests.
The court dismissed the case and ended the plaintiffs' challenge to the emissions regs.
