Opinion for the Court filed by Chief Judge GINSBURG.
Operators of five large-haul truck fleets challenge the Environmental Protection Agency’s refusal to reconsider the 2004 Standard for nitrous oxide (NOx) and non-methane hydrocarbon (NMHC) emissions from “heavy heavy-duty” diesel engines. Because the Trucking Companies have *491 failed to show their injury is fairly traceable to the 2004 Standard, we dismiss their petition for lack of standing under Article III of the Constitution of the United States.
I. Background
In the 1990 Amendments to the Clean Ah’ Act the Congress authorized the EPA to promulgate regulations limiting NOx and NMHC emissions from “classes or categories of heavy-duty vehicles or engines.” 42 U.S.C. § 7521(a)(3)(A)®. The EPA identified three categories of heavy-duty diesel engines for the purpose of regulating emissions: light, medium, and heavy. See 40 C.F.R. § 86.090-2. The Trucking Companies’ petition concerns only the EPA’s regulation of emissions from heavy heavy-duty diesel engines (HHDDEs), which are the engines used in large-haul tractors (truck cabs).
Section 7521(a)(3)(A)® provides that any requirements applicable to heavy-duty engines
shall contain standards which reflect the greatest degree of emission reduction achievable through the application of technology which the Administrator determines will be available for the model year to which such standards apply, giving appropriate consideration to cost, energy, and safety factors associated with the application of such technology.
42 U.S.C. § 7521(a)(3)(A)®. This is a technology-forcing provision; it mandates regulations with which manufacturers can comply only by adopting new technologies as they become available.
The EPA promulgated three emissions standards for HHDDEs. One standard, applicable to engine model years 1998 to 2003, implements the statutory maximum for NOx emissions of “4.0 grams per brake horsepower hour [ (g/bhp-hr) ].” See Control of Emissions of Air Pollution From 2004 and Later Model Year Heavy-Duty Highway Engines and Vehicles, 65 Fed. Reg. 59,896, at 59,898 (Oct. 6, 2000). For model years 2004 to 2006 the standard is a 2.5 g/bhp-hr of NOx plus NMHC. See Control of Emissions of Air Pollution From Highway Heavy-Duty Engines, 62 Fed.Reg. 54,694, at 54,699 (Oct. 21, 1997).
The third standard governs HHDDE emissions in model years 2007 and beyond.
See
Control of Air Pollution From New Motor Vehicles: Heavy-Duty Engine and Vehicle Standards and Highway Diesel Fuel Sulfur Control Requirements, 66 Fed. Reg. 5,002 (Jan. 18, 2001). The 2007 Standard, which we upheld in
National Petrochemical & Refiners Ass’n v. EPA,
In October 1998 the EPA found manufacturers of the vast majority of HHDDEs sold in the United States were attaching “defeat devices” to their engines.
See United States v. Caterpillar,
In 1999 the six manufacturers that produce and sell the vast majority of HHDDEs used in the United States entered into Consent Decrees in which they agreed to end this circumvention of the emissions standards. The manufacturers also agreed to produce by October 2002 engines emitting no more than 2.5 g/bhp-hr of NOx plus NMHC.
See Caterpillar,
In early 2001 the engine manufacturers petitioned the EPA for a rulemaking to permit manufacturers that could not meet the pull-ahead deadline of October 2002 for a limited time to pay a “nonconformance penalty,” as contemplated in 42 U.S.C. § 7525(g). The EPA obliged and set NCPs in August 2002. See Non-Conformance Penalties for 2004 and Later Model Year Emission Standards for Heavy-Duty Diesel Engines and Heavy-Duty Diesel Vehicles, 67 Fed.Reg. 51,464 (Aug. 8, 2002).
The Trucking Companies, armed with the data the engine manufacturers had provided to the EPA during the NCP rule-making, then asked the Administrator to reconsider the 2004 Standard itself. See 42 U.S.C. § 7607(d)(7)(B) (requiring the EPA to “convene a proceeding for reconsideration of the rule” if the petitioning party presents an objection “grounds for [which] arose after the period for public comment (but within the time specified for judicial review) and if such objection is of central relevance to the outcome of the rule”). They claimed the cost of complying with the 2004 Standard will be almost six times the EPA’s estimate.
The EPA denied the Trucking Companies’ petition in February 2003. The Trucking Companies now seek judicial review of that decision on the ground that the EPA’s refusal to reconsider the 2004 Standard was arbitrary and capricious, an abuse of discretion, or otherwise not in accordance with law. See 42 U.S.C. § 7607(d)(9)(A).
II. Analysis
The EPA argues the Trucking Companies lack Article III standing to challenge its decision because, due to the Consent Decrees and the looming 2007 Standard, HHDDE manufacturers will continue to produce engines meeting the 2.5 g/bhp-hr emissions limit even if the 2004 Standard is rescinded. The Trucking Companies respond that they suffer a concrete and particularized injury from the 2004 Standard - increased prices for tractors with engines meeting the 2.5 g/bhp-hr emissions limit - but they completely ignore the EPA’s central point about the independent constraint of the Consent Decrees.
In order to satisfy the “irreducible constitutional minimum of standing,” a petitioner must demonstrate: (1) it has suffered (or is about to suffer) an injury-in-fact, that (2) was caused by the conduct of the respondent and (3) would be redressed by the relief sought from the court.
Lujan v. Defenders of Wildlife,
In order to establish their standing, the Trucking Companies need not demonstrate that if the EPA were to convene a proceeding for reconsideration, then it would relax or rescind the 2004 Standard.
See Defenders of Wildlife,
The six manufacturers that make the great majority of HHDDEs are subject to consent decrees that independently require them, from October 2002 to January 2005, to produce engines that emit no more than 2.5 g/bhp-hr of NOx plus NMHC. Because repeal of the 2004 Standard, which embodies the same limit, would in no way affect the obligations of the engine manufacturers under the Consent Decrees, the entry of judicial relief favorable to the Trucking Companies would have no effect upon the prices they pay for tractors with HHDDEs made by any of those six companies.
See America West Airlines, Inc. v. Burnley,
■ It is possible, of course, that but for the 2004 Standard, the Trucking Companies will .be .able to purchase tractors from a manufacturer that is now bound by a consent decree but might, after that constraint expires on January 1, 2005, decide *494 to produce a pre-October 2002 model engine; but that possibility is sheer speculation. Its actualization depends upon a number of predicate facts, including: (1) an engine manufacturer’s production and design schedule would permit it to shift from producing a compliant 2005 engine to producing a pre-October 2002 engine, notwithstanding the necessity of meeting yet another standard by January 2007; (2) the expected profit of shifting temporarily from producing 2005 engines to producing 2002 engines would exceed the cost of altering production lines; and (3) the per unit price advantage of 2002 engines would be more than sufficient to offset any non-price advantages associated with the 2005 model so as to induce the Trucking Companies to purchase 2002 engines in 2005. All these things may be true, but there is no record evidence to support any of them.
In this regard, the present ease is like
Defenders of Wildlife,
in which the plaintiffs lacked standing to challenge an agency’s failure to follow a consultative procedure allegedly required by the Endangered Species Act before providing aid for certain foreign development projects. The United States’ contribution was “only a fraction” of the cost of the projects, however, and the plaintiffs “produced nothing to indicate that the projects they have named will either be suspended, or do less harm to listed species, if that fraction is eliminated.”
The Trucking Companies offer only assertions, not facts, to support their claims about the likely response of engine manufacturers to repeal of the 2004 Standard. That will not do. Speculative and unsupported assumptions regarding the future actions of third-party market participants are insufficient to establish Article III standing.
