   Opinion for the Court by Circuit Judge ROGERS.

ROGERS, Circuit Judge:

The State of North Carolina petitions for review of the final rule of the Environmental Protection Agency removing the northern part of the State of Georgia from EPA’s regulations under its national ambient air quality standard (“NAAQS”) for ozone measured during a one-hour period. See Petition for Reconsideration and Withdrawal of Findings of Significant Contribution and Rulemaking for Georgia for Purposes of Reducing Ozone Interstate Transport, 73 Fed.Reg. 21,528 (Apr. 22, 2008) (“Withdrawal Rule”). In 1998 EPA called upon several states to revise their state implementation plans (“SIPs”) for attaining the NAAQS for ozone by reducing emissions of oxides of nitrogen (“NOx”), a precursor of ozone. See Finding of Significant Contribution and Rulemaking for Certain States in the Ozone Transport Assessment Group Region for the Purposes of Reducing Regional Transport of Ozone, 63 Fed.Reg. 57,356 (Oct. 27, 1998) (“NOx SIP Call”). Following the remand in Michigan v. EPA, 213 F.3d 663 (D.C.Cir.2000), cert. denied, 532 U.S. 904, 121 S.Ct. 1225, 149 L.Ed.2d 135 (2001), EPA promulgated a rule that included only the northern portion of Georgia in the NOx SIP Call under the one-hour ozone standard. See Interstate Ozone Transport: Response to Court Decisions on the NOx SIP Call, NOx SIP Call Technical Amendments, and Section 126 Rules, 69 Fed.Reg. 21,604 (Apr. 21, 2004) (“Remand Rule”). Georgia’s inclusion was based on EPA’s findings in the NOx SIP Call that emissions from Georgia were significantly contributing to non-attainment of the one-hour ozone NAAQS in Birmingham, Alabama and Memphis, Tennessee. See Withdrawal Rule, 73 Fed.Reg. at 21,530.

Upon the petition of an industry coalition, an intervenor here, EPA reconsidered its inclusion of Georgia in light of its determinations that recently Birmingham, and earlier Memphis, had attained the one-hour ozone standard. See id. North Carolina now challenges the Withdrawal Rule as contrary to EPA policy requiring states’ adherence to NOx emissions budgets based on the one-hour ozone standard after the repeal of the one-hour standard, as non-conformance with the mandate in Michigan v. EPA, and as disparate treatment of Georgia without lawful justification. We do not reach the merits of these contentions because we conclude that North Carolina lacks standing, specifically that North Carolina failed to show redressability-

I.

Nitrogen oxides (NOx) emitted into the air react to form ozone (03), a pollutant with harmful health and environmental effects. Ozone is an interstate issue because NOx emissions and ozone cross into downwind states. See NOx SIP Call, 63 Fed.Reg. at 57,359. In 1979, EPA established the NAAQS for ozone at 0.120 ppm (parts per million) measured over a one-hour period (“the one-hour standard”). Michigan v. EPA, 213 F.3d at 670. In 1997, EPA lowered the ozone NAAQS to 0.08 ppm measured over an eight-hour period (“the eight-hour standard”), id., but this standard was stayed in 2000 and was not before the court in Michigan v. EPA, id. at 671. In 2004, EPA transitioned from the one-hour standard to the eight-hour standard. In 2008, EPA lowered the eight-hour ozone NAAQS to 0.075 ppm.

Meanwhile, in 1998, EPA called for revisions to the SIPs of several upwind states (the “NOx SIP Call”). EPA found that NOx emissions in Georgia significantly contributed (1) to nonattainment of the one-hour ozone standard in Birmingham and Memphis, and (2) to nonattainment of the eight-hour ozone standard in North Carolina. EPA’s 2000 stay of the eight-hour standard “remove[d] the 8-hour findings as a basis for the SIP call.” Michigan v. EPA, 213 F.3d at 671.

On petition for review of the NOx SIP Call, the court held in Michigan v. EPA that “the record does not support ... creating NOx [emissions] budgets based on the entire emissions of Missouri or Georgia,” because only the “fine grid” modeling used for northern Georgia and eastern Missouri, and not the “coarse grid” modeling used for other parts of those states, showed emissions contributing to downwind pollution. Michigan v. EPA, 213 F.3d at 669, 683. On remand, EPA revised the NOx SIP Call by calculating NOx emissions budgets based only on areas of Georgia and Missouri whose emissions had been modeled for the NOx SIP Call with the fine-grid technique. See Remand Rule, 69 Fed.Reg. at 21,624. The Remand Rule was published April 21, 2004, with an effective date of June 21, 2004. However, EPA had found, effective April 12, 2004, that Birmingham (and earlier, Memphis) had attained the one-hour ozone standard. In response to a petition from intervenor Georgia Coalition for Sound Environmental Policy (a group of businesses and companies, hereinafter “industry”), EPA stayed the Remand Rule with respect to Georgia during the notice and comment proceedings for industry’s petition to reconsider Georgia’s inclusion in the NOx SIP Call, in light of EPA’s Birmingham and Memphis findings. In 2008, EPA finalized the Withdrawal Rule, removing Georgia from the one-hour NOx SIP Call.

In petitioning for review, North Carolina claims that NOx emissions from electric generating units (“EGUs”) in northern Georgia are significantly contributing to North Carolina’s inability to attain the NAAQS under the eight-hour standard due to Georgia’s non-inclusion in the one-hour NOx SIP Call, and that North Carolina’s injury can be remedied by vacating the Withdrawal Rule in part. Specifically, North Carolina seeks partial vacatur of the Withdrawal Rule, reinstatement of the pri- or 40 C.F.R. § 51.121 regulations and removal of the stay of the regulations with respect to Georgia under subparagraph (s) of section 51.121, and instructions on Georgia’s deadline for submitting a compliant SIP. On the merits, North Carolina challenges the Withdrawal Rule on three grounds: EPA’s noncompliance with a policy requiring states to adhere to emission budgets set under the one-hour standard after that standard was abolished; EPA’s noncompliance with the mandate in Michigan v. EPA, specifically by relying on new data in promulgating the Withdrawal Rule; and EPA’s disparate treatment of Georgia as compared to Missouri and other states in the original NOx SIP Call. Industry, however, challenges North Carolina’s standing under Article III of the United States Constitution, maintaining that EPA correctly stated during the rulemaking that Georgia may already be meeting the requirements of the one-hour NOx SIP Call, see Withdrawal Rule, 73 Fed.Reg. at 21,534, and that consequently North Carolina cannot show redressability. We turn to that threshold question.

II.

In Lujan v. Defenders of Wildlife, 504 U.S. 555, 112 S.Ct. 2130, 119 L.Ed.2d 351 (1992), the Supreme Court described the Article III injury, causation, and redressability requirements for standing:

First, the plaintiff must have suffered an “injury in fact” — an invasion of a legally protected interest which is (a) concrete and particularized, and (b) “actual or imminent, not ‘conjectural’ or ‘hypothetical.’ ” Second, there must be a causal connection between the injury and the conduct complained of — the injury has to be “fairly ... trace[able] to the challenged action of the defendant, and not ... th[e] result [of] the independent action of some third party not before the court.” Third, it must be “likely,” as opposed to merely “speculative,” that the injury will be “redressed by a favorable decision.”

Id. at 560-61, 112 S.Ct. 2130 (alterations in Lujan; citations and footnote omitted). “When the suit is one challenging the legality of government action or inaction,” and “a plaintiffs asserted injury arises from the government’s allegedly unlawful regulation (or lack of regulation) of someone else” and “the plaintiff is not himself the object of the government action or inaction he challenges,” then “standing is not precluded, but it is ordinarily substantially more difficult to establish.” Id. at 562, 112 S.Ct. 2130 (emphasis and quotation marks omitted).

North Carolina’s situation is similar in many respects to that of Massachusetts in Massachusetts v. EPA, 549 U.S. 497, 127 S.Ct. 1438, 167 L.Ed.2d 248 (2007). There the Supreme Court held that Massachusetts had standing to challenge EPA’s failure to regulate certain air pollutants, because Massachusetts has “quasi-sovereign interests” in reducing air pollution and a procedural right to challenge EPA under 42 U.S.C. § 7607(b)(1). Massachusetts v. EPA, 549 U.S. at 519-21, 127 S.Ct. 1438. Like Massachusetts, North Carolina is a state challenging EPA’s rule pursuant to 42 U.S.C. § 7607(b)(1) in order to reduce its air pollution, which entitles North Carolina to “special solicitude in our standing analysis.” Massachusetts v. EPA, 549 U.S. at 520, 127 S.Ct. 1438. In addition, “[wjhen a litigant is vested with a procedural right, that litigant has standing if there is some possibility that the requested relief will prompt the injury-causing party to reconsider the decision that allegedly harmed the litigant.” Id. at 518, 127 S.Ct. 1438.

North Carolina contends that because EPA has recognized ozone as a harmful pollutant (injury), and because EPA recognized in 1998 that ozone from Georgia contributed to North Carolina’s non-attainment of the 1997 eight-hour ozone standard (causation), and because re-including northern Georgia in the NOx SIP Call would likely reduce Georgia’s emissions (redressability), it has established standing. Nonetheless North Carolina acknowledged during oral argument that notwithstanding any “special solicitude” to which it may be entitled as a sovereign state, it must demonstrate Article III standing. We conclude the redressability requirement is not satisfied.

North Carolina contends that it has standing because it is having difficulty meeting federal eight-hour ozone standards due to emissions from Georgia. With its opening brief, see Sierra Club v. EPA, 292 F.3d 895, 900-01 (D.C.Cir.2002), North Carolina submitted an affidavit in support of its standing from the Deputy Director of the Division of Air Quality of the North Carolina Department of Environment and Natural Resources, Sheila Holman. The Holman Affidavit states that North Carolina has areas located close to Georgia that are not attaining the 1997 eight-hour ozone standard, and concludes that NOx emissions from northern Georgia impact ozone levels in North Carolina, based in part on an attached report by Dr. Saravanan Arunachalam that concluded Georgia’s emissions likely contributed significantly to North Carolina’s non-attainment in 2005. North Carolina also points out that EPA has recognized that an area’s proximity to an emissions source contributes to the effects from that source. See Remand Rule, 69 Fed.Reg. at 21,625. North Carolina contends that the Holman Affidavit and the Arunachalam Report establish North Carolina’s injury and show that Georgia partially causes this injury. Re-including northern Georgia in the NOx SIP Call, North Carolina concludes, would reduce Georgia’s contributions to North Carolina’s ozone, and thus redress North Carolina’s injury by helping it meet its federal 1997 and 2008 eight-hour ozone standard obligations, as well as improve its overall air quality.

In challenging North Carolina’s standing, industry’s objections regarding injury and causation are not well taken. Industry’s preliminary contention that North Carolina lacks standing because it discussed its injury in terms of the stayed 1997 and new 2008 eight-hour ozone standards, rather than the NOx SIP Call’s one-hour ozone standard, is unpersuasive. As North Carolina responds, ozone is ozone no matter how it is measured, and if re-including Georgia in the NOx SIP Call reduces ozone under the one-hour standard, it would presumably reduce ozone under the eight-hour standard as well.

Likewise, industry’s position that the Withdrawal Rule could not cause North Carolina injury is unpersuasive. Industry suggests that North Carolina has alleged injuries only from Georgia, rather than from EPA’s Withdrawal Rule, and that under Center for Biological Diversity v. U.S. Department of the Interior, 563 F.3d 466, 478 (D.C.Cir.2009), North Carolina has failed to show that its injury results from actions of EPA, rather than the discretionary actions of a third party. But North Carolina, like the state in Massachusetts v. EPA has standing to challenge EPA’s failure to regulate a third party because that failure assertedly causes injury, see also South Coast Air Quality Management District v. EPA 472 F.3d 882, 895-96 (D.C.Cir.2006), and Georgia is not an absent third party because it would not have discretion not to meet the NOx SIP Call if it were subject to the NOx SIP Call.

To the extent industry emphasizes that North Carolina’s standing burden is heavier both because it is not the object of EPA’s Withdrawal Rule, and because no interstate NOx emissions are keeping North Carolina from meeting the one-hour ozone standard that was the basis of the NOx SIP Call, North Carolina persuasively maintains it should not be more difficult for it to establish standing, because its injury, causation, and redressability are more clear than in Center for Biological Diversity, in which this court stated a party could not establish standing where causation was based on “speculation” about the discretionary future acts of various entities, 563 F.3d at 479. Rather, what is ultimately dispositive is the showing in submissions by intervenor Georgia Environmental Protection Division (“the Division”) that reinstating the NOx SIP Call for Georgia is not likely to redress North Carolina’s injuries.

Preliminarily we note that certain of intervenors’ contentions miss the mark. Industry contends that because North Carolina has attained the one-hour ozone standard in the NOx SIP Call, re-including Georgia in the NOx SIP Call will not redress North Carolina’s injury, but industry and North Carolina appear to be defining “injury” differently: industry contends that the NOx SIP Call involves injuries only from not meeting the one-hour ozone standard, whereas North Carolina contends that any reduction in NOx emissions due to the NOx SIP Call would also help North Carolina meet the eight-hour ozone standards. Industry and the Division next contend that re-including Georgia in the NOx SIP Call would actually increase emissions by creating excess emission allowances that others could buy to increase their emissions. However, North Carolina responds that Georgia need not opt into the allowance program.

North Carolina’s ability to show redress-ability hinges on showing that including northern Georgia in the NOx SIP Call would result in reducing emissions from Georgia that significantly contribute to North Carolina’s inability to reach attainment under the 1997 NAAQS standard. If lower emissions would result from Georgia’s inclusion, then the Withdrawal Rule is the cause of North Carolina’s injury and its injury is redressable by vacating the rule in part with instructions. In reply to intervenors’ statements that Georgia’s recent NOx emissions have been below the NOx emissions cap that would have applied to Georgia under the Remand Rule, North Carolina provides a rebuttal affidavit from Sheila Holman listing Georgia’s EGU NOx emission levels in 2007 and 2008, which North Carolina concludes exceeded the Remand Rule’s NOx emissions cap. Based on the emissions data in North Carolina’s reply brief, it reasonably concludes that Georgia’s emissions have exceeded the limits of the NOx SIP Call, and perhaps as well that Georgia’s own rules limiting emissions would have a lesser effect on emissions than the NOx SIP Call would. However, intervenors challenge North Carolina’s showing of emission levels. To assist the court in determining whether it has jurisdiction, it permitted the Division to file a supplemental reply on standing, most particularly as it concerns redressability. See, e.g., Am. Library Ass’n v. FCC, 401 F.3d 489, 494 (D.C.Cir.2005).

The Division’s sur-reply provides an analysis suggesting that North Carolina’s Holman Rebuttal Affidavit reports emissions from the entire state of Georgia rather than only from the northern two-thirds of Georgia that would have been subject to the NOx SIP Call after the remand in Michigan v. EPA. The Division attaches to its sur-reply an affidavit from the Chief of the Georgia Air Protection Branch of the Georgia Environmental Protection Division, James A. Capp, stating that Georgia’s EGUs, in the portion of Georgia that would have been subject to the Remand Rule of the NOx SIP Call, emitted 31,804 tons of NOx in 2007 and 31,057 tons in 2008. The Capp Affidavit also states that Georgia’s NOx emissions budget under the Remand Rule would have been 29,416 tons. Thus, as industry conceded at oral argument, Georgia’s 2007 and 2008 NOx emissions would have exceeded the Remand Rule’s cap if Georgia would not have been able to use allowances or credits to increase its cap.

However, the Division’s sur-reply also provides an analysis indicating that Georgia would have met the Remand Rule’s NOx emissions cap through the use of EPA’s compliance supplement pool (“CSP”) allowances. EPA has stated in the Federal Register that the CSP is a voluntary provision of the NOx SIP Call that provides emissions credits to states to allocate in order to cover excess emissions under certain circumstances. See NOx SIP Call, 63 Fed.Reg. at 57,428, 57,493. Under the Remand Rule, EPA would authorize CSP credits to Georgia of up to 10,728 tons of NOx, if Georgia meets the CSP requirements. See Remand Rule, 69 Fed.Reg. at 21,629-30, 21,643-44. In its reply brief, North Carolina suggests in a footnote that Georgia’s emissions may not qualify for any available CSP credits. However, counsel for EPA advised the court during oral argument that EPA generally has approved a CSP allowance in states subject to the NOx SIP Call. Oral Arg. Tape at 29:12-29:43. In addition, the Capp Affidavit states that Georgia would have used its CSP allowance to meet the Remand Rule’s NOx emissions cap. During oral argument North Carolina’s only response was to question Georgia’s ability to qualify for any authorized CSP credits. North Carolina offered no data and cited no statute, regulation, or EPA policy that would bar Georgia from accessing any CSP credits. It appears likely, then, that if Georgia had been subject to the NOx SIP Call under the Remand Rule, Georgia would have used CSP credits to comply with the NOx emissions cap and would not have needed to lower its emissions to meet the requirements of the NOx SIP Call.

The Division’s showing in its sur-reply that Georgia intends to use CSP credits to cover its excess emissions thus resolves the question of redressability, for North Carolina can no longer show that vacating the Withdrawal Rule and re-including northern Georgia in the NOx SIP Call is likely to redress North Carolina’s difficulty in meeting the 1997 NAAQS eight-hour ozone standard. As counsel for North Carolina stated at oral argument, if reinstating Georgia in the NOx SIP Call would not lower Georgia’s emissions, then North Carolina has a standing problem. Accordingly, we dismiss North Carolina’s petition for lack of standing. 
      
      . In 2005, EPA also began regulating NOx emissions using the eight-hour ozone standard under the Clean Air Interstate Rule ("CAIR”). See Rule To Reduce Interstate Transport of Fine Particulate Matter and Ozone (Clean Air Interstate Rule); Revisions to Acid Rain Program; Revisions to the NOx SIP Call, 70 Fed.Reg. 25,162 (May 12, 2005); see also North Carolina v. EPA, 531 F.3d 896 (D.C.Cir.2008), remanded without vacatur, 550 F.3d 1176 (D.C.Cir.2008).
     
      
      . In response to industry’s assertion that the reference in the Holman Affidavit to “a cap” is not specific enough to allege injury, North Carolina provided a rebuttal affidavit clarifying that the cap in the affidavit was the cap from the NOx SIP Call.
