    Before: RAO and WALKER, Circuit Judges, and

    Opinion for the Court filed by Circuit Judge RAO.
    RAO, Circuit Judge: The Alaska Gasline Development
    Corporation sought authorization to build and operate a system
    of natural gas facilities. After the Federal Energy Regulatory
    Commission granted that authorization, the Center for
    Biological Diversity and the Sierra Club (collectively, “CBD”)
    petitioned this court for review. Some of the issues CBD raises
    were not exhausted, and we lack jurisdiction to consider them.
    We reject CBD’s other arguments on the merits. FERC’s
    decision to authorize the Alaska Liquid Natural Gas Project
    was lawful and reasonable. We dismiss the petition in part and
    deny it in part.
    I.
    A.
    The Corporation seeks to build liquefied natural gas
    (“LNG”) facilities in Alaska’s northernmost region, known as
    the North Slope. There are many productive natural gas wells
    in this region, and they produce more gas than current
    infrastructure can liquefy, ship, and bring to market. Due to
    these infrastructure limitations, much of the gas coming from
    the North Slope is reinjected into the ground to bolster internal

    time the case was argued but did not participate in the opinion.
    3
    pressure and make extraction easier. Reinjection is a relatively
    low value use for natural gas.
    The proposed Project would employ North Slope natural
    gas for more economically beneficial uses by building facilities
    to uptake the gas and ready it for pipeline transportation. The
    gas would be transported by a 42-inch diameter pipeline over
    800 miles in length, bisecting Alaska from north to south. The
    pipeline would partially trace the path of an existing crude oil
    line. The Project also includes the construction of natural gas
    liquefaction facilities in the south of Alaska, near the Cook
    Inlet. Liquefaction reduces the volume of the gas and makes it
    easier to export by tanker ship. The Corporation has tentative
    plans to reroute some of the gas, before liquefaction, for use in
    Alaska. Project facilities are anticipated to uptake, transport,
    liquefy, and export substantial volumes of natural gas for at
    least 30 years.
    B.
    The Corporation sought FERC approval for its Project.
    When considering an application for an LNG facility, FERC
    must comply with the National Environmental Policy Act
    (“NEPA”), 
    Pub. L. No. 91-190, 83
     Stat. 852 (1970) (codified
    as amended at 
    42 U.S.C. § 4321
     et seq.). Under NEPA, FERC
    was required to prepare an Environmental Impact Statement
    (“EIS”) because the Project was a “major Federal action[]
    significantly affecting the quality of the human environment.”
    
    42 U.S.C. § 4332
    (2)(C). FERC also must comply with the
    Natural Gas Act (“NGA”), 
    Pub. L. No. 75-688, 52
     Stat. 821
    (1938) (codified as amended at 
    15 U.S.C. § 717
     et seq.). The
    Commission must authorize the facility unless doing so would
    “not be consistent with the public interest.” 15 U.S.C.
    § 717b(a).
    4
    To comply with NEPA’s procedural requirements, the
    Commission prepared a roughly 1,500 page EIS, which
    analyzed the Project along a number of dimensions, including
    the potential impacts on wetlands, marine mammals, fish,
    drinking water, carbon dioxide levels, rivers, soils, permafrost,
    vegetation, the aesthetics of Denali National Park, and Alaskan
    socioeconomics. The Commission evaluated alternatives to the
    Project and analyzed mitigation measures that could help
    reduce certain environmental impacts. The Commission
    concluded the Project would cause a range of temporary, long-
    term, and permanent environmental impacts.
    The Commission authorized the Project subject to 165
    environmental conditions. Order Granting Authorization
    Under Section 3 of the Natural Gas Act (“Authorization
    Order”), 
    171 FERC ¶ 61,134
     (May 21, 2020). The Commission
    found that the conditions would adequately mitigate the
    environmental impacts and that, as modified, the Project would
    be consistent with the public interest. CBD petitioned for
    rehearing, arguing that the EIS was deficient in various ways
    and that FERC had not adequately determined the Project was
    within the public interest. FERC denied rehearing. Order
    Addressing Arguments Raised on Rehearing (“Rehearing
    Order”), 
    172 FERC ¶ 61,214
     (Sept. 11, 2020).
    CBD timely petitioned for review of the Authorization and
    Rehearing Orders, and we granted the Corporation’s motion to
    intervene on behalf of FERC. We have jurisdiction to review
    the petition under the NGA. See 15 U.S.C. § 717r(b).
    II.
    CBD challenges the Authorization and Rehearing Orders
    for failure to comply with NEPA and its implementing
    regulations. We review NEPA challenges under the familiar
    standards of the Administrative Procedure Act (“APA”) to
    5
    determine whether the agency action was arbitrary and
    capricious or contrary to law. City of Oberlin v. FERC, 
    39 F.4th 719
    , 725 (D.C. Cir. 2022); 
    5 U.S.C. § 706
    (2)(A). NEPA
    requires agencies to “take a hard look at the environmental
    consequences before taking a major action.” Balt. Gas & Elec.
    Co. v. Nat. Res. Def. Council, Inc., 
    462 U.S. 87
    , 97 (1983)
    (cleaned up). Agencies evaluate these consequences in an EIS,
    which must consider:
    (i) the environmental impact of the proposed
    action, (ii) any adverse environmental effects
    which cannot be avoided should the proposal be
    implemented, (iii) alternatives to the proposed
    action, (iv) the relationship between local short-
    term uses of man’s environment and the
    maintenance and enhancement of long-term
    productivity, and (v) any irreversible and
    irretrievable commitments of resources which
    would be involved in the proposed action
    should it be implemented.
    
    42 U.S.C. § 4332
    (2)(C).
    NEPA is a purely procedural statute, and an agency
    therefore enjoys latitude when preparing an EIS. We will not
    set aside an agency action on NEPA grounds if the EIS
    “contains sufficient discussion of the relevant issues and
    opposing viewpoints and the agency’s decision is fully-
    informed and well-considered.” Gulf Restoration Network v.
    Haaland, 
    47 F.4th 795
    , 799–800 (D.C. Cir. 2022) (cleaned up).
    NEPA requires agencies to evaluate the environmental effects
    of their actions, but the “[p]reparation of an environmental
    impact statement will never force an agency to change the
    course of action it proposes.” Lemon v. Geren, 
    514 F.3d 1312
    ,
    1315 (D.C. Cir. 2008) (cleaned up).
    6
    CBD maintains the Commission failed to comply with
    NEPA and its implementing regulations in five ways. We
    conclude that CBD’s arguments are either not exhausted or fail
    on the merits.
    A.
    CBD first argues the Commission inadequately considered
    alternatives to the Project in contravention of NEPA’s
    implementing regulations.1 An agency must both evaluate a
    “no action” alternative to the proposed agency action and must
    “[r]igorously explore and objectively evaluate all reasonable
    alternatives” to the action.2 
    40 C.F.R. § 1502.14
    (a)–(d) (2020);
    Gulf Restoration Network, 47 F.4th at 800. An alternative is
    reasonable if it is “technically and economically practical or
    feasible and meet[s] the purpose and need of the proposed
    action.” 
    43 C.F.R. § 46.420
    (b) (2019). As we have recognized,
    “NEPA’s injunction that agencies consider the environmental
    impacts of ‘all reasonable alternatives’ does not substantively
    constrain an agency’s choice of objectives.” City of Alexandria
    v. Slater, 
    198 F.3d 862
    , 867 (D.C. Cir. 1999). Because some
    alternatives will be impractical or fail to further the proposed
    1
    FERC does not contest that NEPA implementing regulations, which
    are promulgated by the Council on Environmental Quality, bind it.
    Cf. Nevada v. Dep’t of Energy, 
    457 F.3d 78
    , 87 n.5 (D.C. Cir. 2006)
    (“Because the [Council] has no express regulatory authority under
    NEPA—it was empowered to issue regulations only by executive
    order—the binding effect of [Council] regulations is far from clear.”)
    (cleaned up).
    2
    
    40 C.F.R. § 1502
     and 
    40 C.F.R. § 1508
     have since been amended,
    but the amendment did not take effect until after FERC had entered
    the Orders. See Update to the Regulations Implementing the
    Procedural Provisions of the National Environmental Policy Act, 
    85 Fed. Reg. 43,304
    , 43,365, 43,374 (July 16, 2020) (effective Sept. 14,
    2020). We cite the regulations in effect at the time of the Orders.
    7
    action’s purpose, agencies may reject unreasonable alternatives
    after only brief discussion.
    1.
    CBD faults FERC for discussing in tandem the true no-
    action alternative (where nothing like the Project is ever built)
    and the likely no-action alternative (where something like the
    Project is built). CBD maintains this way of analyzing the no-
    action alternative was unreasonable and so confusing that it
    “misled the public and disguised the proposal’s true
    significance.”
    The Commission reasonably analyzed the relevant no-
    action alternatives. First, the Commission considered an
    alternative in which, after FERC denied approval, nothing like
    the Project would be built. FERC rejected this true no-action
    alternative because it would not fulfill the Project’s purpose,
    which is to commercialize natural gas from Alaska’s North
    Slope. CBD does not contest that FERC accurately
    characterized the Project’s purpose. FERC’s concise rejection
    of this alternative was reasonable because the Project’s purpose
    was commercialization of North Slope gas. 
    40 C.F.R. § 1502.14
    (a).
    Second, the Commission analyzed the likely no-action
    alternative. If this Project were not approved, FERC recognized
    that substantial incentives would remain to commercialize the
    North Slope’s plentiful gas by building something like the
    Project. FERC reasonably rejected the likely no-action
    alternative because any proposal for North Slope gas
    development would have similar environmental impacts to
    those of the Project. It was reasonable for the Commission to
    consider the reality of economic and development
    opportunities and reject an alternative that would not
    8
    appreciably reduce environmental         impacts.    See   Gulf
    Restoration Network, 47 F.4th at 800.
    Nor was the Commission’s analysis confusing. When
    “reviewing an agency’s compliance with NEPA, the rule of
    reason applies, and we consistently decline to flyspeck an
    agency’s environmental analysis.” Minisink Residents for
    Env’t Preservation & Safety v. FERC, 
    762 F.3d 97
    , 112 (D.C.
    Cir. 2014) (cleaned up). In the EIS, Authorization Order, and
    Rehearing Order, FERC considered and reasonably rejected the
    no-action alternatives consistent with NEPA and the APA.
    2.
    CBD also argues the Commission’s consideration of
    alternatives falls short because FERC had to evaluate each
    alternative along every dimension of environmental impact
    used to analyze the Project. According to CBD, this parallel
    evaluation is required because FERC must “present the
    environmental impacts of the proposal and the alternatives in
    comparative form, thus sharply defining the issues and
    providing a clear basis for choice among options by the
    decisionmaker and the public.” 
    40 C.F.R. § 1502.14
    ; see also
    
    id.
     § 1502.14(a) (requiring the agency to “[r]igorously explore
    and objectively evaluate all reasonable alternatives”).
    Rigorously evaluating alternatives means that agencies
    must assess and compare the environmental impacts of
    reasonable alternatives. But it does not require assessing each
    alternative under identical criteria. Some alternatives will be
    more reasonable than others based on their economic and
    technological feasibility and how well they serve the purposes
    of the proposed action. The agency need not provide the same
    level of detailed analysis for each alternative that it provides
    for the action under review.
    9
    The Commission considered reasonable alternatives and
    rejected them because they would not reduce environmental
    impacts.3 FERC considered the Project’s impacts along 23
    dimensions. FERC then assessed each alternative under some
    of these 23 dimensions and concluded that no alternative
    offered a significant environmental advantage over the Project,
    and in fact some alternatives would impose substantially more
    environmental harm. For example, FERC rejected a proposed
    alternative because it would have disturbed more than 6,000
    additional acres of land while achieving essentially the same
    end results as the Project.
    FERC’s analysis comported with the law. When an
    alternative has greater projected environmental impacts than
    the action under review, no statute or regulation prevents the
    Commission from rejecting the alternative on that ground. It
    would hardly further NEPA’s mandate for informed
    decisionmaking to require the Commission to analyze
    obviously inferior alternatives along additional dimensions of
    environmental impact.
    CBD also contends FERC should have more thoroughly
    considered an alternative pipeline route that would have
    avoided a state game refuge. Because CBD failed to exhaust
    this issue in its application for rehearing, and because it
    provides no reasonable ground for this failure, we lack
    jurisdiction to consider it. See 15 U.S.C. § 717r(a); id.
    § 717r(b) (“No objection to the order of the Commission shall
    be considered by the court unless such objection shall have
    been urged before the Commission in the application for
    3
    FERC deemed some alternatives unreasonable, see 
    43 C.F.R. § 46.420
    (b), and rejected those with only brief explanation, see 
    40 C.F.R. § 1502.14
    (a). CBD does not challenge those parts of FERC’s
    analysis.

    rehearing unless there is reasonable ground for failure so to
    do.”); Food & Water Watch v. FERC, 
    28 F.4th 277
    , 284 (D.C.
    Cir. 2022) (holding the NGA’s issue exhaustion requirement is
    jurisdictional).
    B.
    CBD next argues the Commission acted arbitrarily and
    contrary to law by refusing to employ the “social cost of
    carbon” metric to estimate the significance of the Project’s
    direct emissions of greenhouse gases.
    FERC estimated the Project’s annual volume of direct
    emissions and compared these projections with existing
    Alaskan and nationwide emissions. The Commission
    concluded the Project’s direct emissions would cause a “30–47
    percent increase in the annual fossil-fuel combustion inventory
    in Alaska” and a “0.17–0.28 percent increase in national”
    emissions. It surveyed several methods for estimating the
    Project’s effects on global climate change, but it concluded
    these methods were either too broad in “scale and
    overwhelming [in] complexity” or simply unreliable. The
    absence of an adequate methodology, combined with a lack of
    either state or federal emissions benchmarks, left FERC unable
    to assess the Project’s causal effect (if any) on global climate
    change.
    Rather than use the social cost of carbon, the Commission
    compared the Project’s direct emissions with existing Alaskan
    and nationwide emissions. It declined to apply the social cost
    of carbon for the same reasons it had given in a previous order.
    Authorization Order, 
    171 FERC ¶ 61,134
     at PP 42–43 (citing
    Order Issuing Certificates and Granting Abandonment
    Authority, 
    161 FERC ¶ 61,043
     at P 296 (Oct. 13, 2017)). First,
    the Commission recognized the lack of consensus about how
    to apply the social cost of carbon on a long time horizon.
    11
    Second, it noted the social cost of carbon places a dollar value
    on carbon emissions but does not measure environmental
    impacts as such. Third, FERC has no established criteria for
    translating these dollar values into an assessment of
    environmental impacts.
    FERC’s approach was reasonable and mirrors analysis we
    have previously upheld. In EarthReports, Inc. v. FERC, the
    Commission rejected the social cost of carbon for the same
    three reasons it offered in this case. 
    828 F.3d 949
     (D.C. Cir.
    2016). We held FERC had not “acted unreasonably in finding
    the [social cost of carbon] tool inadequately accurate to warrant
    inclusion under NEPA” analysis.4 
    Id. at 956
    . As in
    EarthReports, FERC had no obligation in this case to consider
    the social cost of carbon.
    CBD also contends the Commission acted contrary to law
    because NEPA regulations require agencies to consider
    “theoretical approaches or research methods generally
    accepted in the scientific community.” 
    40 C.F.R. § 1502.22
    (b)(4). In support of its view that the social cost of
    carbon is such a method, CBD invokes Vecinos para el
    Bienestar de la Comunidad Costera v. FERC, which remanded
    a FERC order for (inter alia) failure to consider whether 
    40 C.F.R. § 1502.22
     mandates a social cost of carbon analysis.5 6
    4
    We have since reached the same conclusion in two unpublished
    opinions. Sierra Club v. FERC, 
    672 F. App’x 38
    , 39 (D.C. Cir. 2016)
    (per curiam) (“This Court has already considered and rejected
    identical arguments relating to the social cost of carbon.”);
    Appalachian Voices v. FERC, 
    2019 WL 847199
    , at *2 (D.C. Cir.
    Feb. 19, 2019) (per curiam).
    5
    What was 
    40 C.F.R. § 1502.22
     when FERC did its analysis in 2020
    has since been relocated to 
    40 C.F.R. § 1502.21
    . See Vecinos, 6 F.4th
    at 1328 (using the provision’s new location).
    
    12 F.4th 1321
    , 1328–30 (D.C. Cir. 2021). CBD’s argument is in
    tension with EarthReports and subsequent cases in which we
    found it permissible not to apply the social cost of carbon
    methodology because of the lack of scientific consensus. 
    828 F.3d at 956
    .
    In any event, we lack jurisdiction to consider this issue
    because CBD’s rehearing petition did not raise it. See 15 U.S.C.
    § 717r(a), (b); Food & Water Watch, 28 F.4th at 284. CBD
    discussed the social cost of carbon in its petition but did not
    root its argument in 
    40 C.F.R. § 1502.22
    . CBD cited the
    regulation one time, in a “see, e.g.,” citation. That was not
    sufficient to put FERC on notice, and it certainly does not
    amount to “set[ting] forth [the argument] specifically.” 15
    U.S.C. § 717r(a); see also Ameren Servs. Co. v. FERC, 
    893 F.3d 786
    , 793 (D.C. Cir. 2018) (explaining “objections may not
    be preserved either indirectly or implicitly”) (cleaned up). This
    case is therefore unlike Vecinos, where we noted the petitioner
    specifically raised the applicability of 
    40 C.F.R. § 1502.22
     in
    its comments before the Commission and in its rehearing
    petition. 6 F.4th at 1328.
    C.
    CBD next argues the Commission violated NEPA and its
    implementing regulations by refusing to consider the Project’s
    indirect greenhouse gas emissions. A liquid natural gas project
    can cause two kinds of indirect emissions. Upstream emissions
    result from the process of extracting natural gas. Downstream
    emissions are released when end users burn natural gas. See
    EarthReports, 
    828 F.3d at
    955–56 (discussing both kinds of
    emissions).
    At the outset of the EIS, FERC explained the Project’s
    natural gas would either be exported to foreign buyers or sold
    to domestic users in Alaska. With respect to export-bound gas,
    13
    the Department of Energy has exclusive jurisdiction over
    whether to approve natural gas exports, and therefore the
    Commission “does not have authority over, and need not
    address the effects of, the anticipated export of the gas.”
    Authorization Order, 
    171 FERC ¶ 61,134
     at P 41. In fact,
    FERC is “forbidden to rely on the effects of gas exports as a
    justification for denying” permission to an LNG project. Sierra
    Club v. FERC, 
    867 F.3d 1357
    , 1372–73 (D.C. Cir. 2017)
    (emphasis omitted). FERC’s lack of jurisdiction over export
    approvals also means it has “no NEPA obligation stemming
    from th[e] effects” of export-bound gas. 
    Id.
     at 1372 (citing
    Dep’t of Transp. v. Pub. Citizen, 
    541 U.S. 752
     (2004)). FERC
    properly recognized the limits of its delegated statutory
    authority and cabined its NEPA analysis accordingly.
    Attempting to avoid these clear jurisdictional lines, CBD
    maintains FERC’s decision whether to approve the Project and
    Energy’s decision whether to approve exports are “connected
    actions” that cannot be segmented in the NEPA analysis. See
    
    40 C.F.R. § 1508.25
    (a)(1) (2020) (providing an agency must
    consider “[c]onnected actions, which means [actions that] are
    closely related” to the action the agency is contemplating); Del.
    Riverkeeper Network v. FERC (“Delaware Riverkeeper I”),
    
    753 F.3d 1304
    , 1313–19 (D.C. Cir. 2014). These regulations
    ensure that agencies consider the environmental impacts of
    closely related actions; however, they do not, and cannot,
    expand FERC’s jurisdiction. We decline to adopt CBD’s
    aggressive reading of 
    40 C.F.R. § 1508.25
    , which conflicts
    with our precedent and would require the Commission to
    consider the indirect effects of actions beyond its delegated
    authority.
    The Commission’s discussion of Alaska-bound gas also
    comported with regulatory requirements. An agency must
    consider only a project’s “reasonably foreseeable” effects, 
    id.
    14
    § 1508.8(b), and indirect emissions are not reasonably
    foreseeable if the Commission cannot identify the end users of
    the gas, Del. Riverkeeper Network v. FERC (“Delaware
    Riverkeeper II”), 
    45 F.4th 104
    , 110 (D.C. Cir. 2022). FERC
    acknowledged the Corporation’s plans to install at least three
    taps along the Project’s pipeline and to divert some natural gas
    for sale and use in Alaska. But before these plans could come
    to fruition, the Corporation would have to contract with
    prospective customers and secure regulatory approval from
    Alaska, and various subsidiary pipelines (none of which had
    been proposed) would have to be built. Given these
    uncertainties, the Commission explained that the extent, scope,
    and location of any future interconnections were unknown.
    Because FERC could not reasonably identify the end users of
    the gas, its decision not to consider the indirect effects of
    Alaska-bound gas was lawful. See 
    40 C.F.R. § 1508.8
    (b);

    and for an unknown end use”).

    CBD next argues the Commission did not adequately
    consider the impact of the Project on the endangered Cook Inlet
    beluga whales.6 It maintains FERC’s analysis was so cursory
    as to be arbitrary and capricious, and that FERC failed to
    consider “cumulative impacts.”
    First, CBD maintains the Commission did not take a hard
    look at the impacts of vessel noise on the belugas. We

    population. We use the term “belugas” here to refer specifically to
    Cook Inlet belugas.
    15
    conclude, however, that FERC’s EIS—along with the
    Biological Assessment of the National Marine Fisheries
    Service (“NMFS”)—was adequately reasoned. The
    Commission discussed underwater sources of noise (e.g., pile
    driving, excavation, and dredging), and included a section
    dedicated to vessel noise. The Commission also acknowledged
    that the Project would cause an increase in Cook Inlet vessel
    traffic and that the resulting increases in noise “could
    disrupt … [the] dive behavior, movements, and vocal activity
    of whales.” To protect belugas and other marine mammals
    from Project noise, FERC imposed a series of mitigation
    measures that went beyond those measures proposed by the
    Corporation. The Commission found these measures brought
    the Project within the public interest.
    CBD proposes alternative ways to analyze the Project’s
    impact on belugas, but it fails to demonstrate the Commission’s
    analysis was unreasonable. To the extent CBD suggests FERC
    had to address belugas in a separate section of the EIS, we
    “decline to flyspeck an agency’s environmental analysis” by
    imposing formatting requirements. Minisink, 
    762 F.3d at 112
    (cleaned up). To the extent CBD simply disagrees with FERC’s
    decision to approve the Project despite its potential impacts on
    belugas, NEPA does not compel any particular policy decision
    by the agency. Rather, NEPA ensures only that an agency has
    assessed the environmental impacts of proposed actions before
    authorization. Lemon, 
    514 F.3d at 1315
    . The Commission
    carefully identified potential threats to belugas, analyzed their
    magnitude, and imposed targeted mitigation measures. This
    approach was entirely reasonable.
    Second, CBD argues the Commission did not adequately
    consider the Project’s “cumulative impacts” on beluga whales.
    Cumulative impacts are “the impact[s] on the environment
    which result[] from the incremental impact of the [proposed
    16
    agency] action when added to other past, present, and
    reasonably foreseeable future actions regardless of what
    agency … or person undertakes such other actions.”7 
    40 C.F.R. § 1508.7
     (2020). As we have explained:
    [A] meaningful cumulative impact analysis
    must identify (1) the area in which the effects of
    the proposed project will be felt; (2) the impacts
    that are expected in that area from the proposed
    project; (3) other actions—past, present, and
    proposed, and reasonably foreseeable—that
    have had or are expected to have impacts in the
    same area; (4) the impacts or expected impacts
    from these other actions; and (5) the overall
    impact that can be expected if the individual
    impacts are allowed to accumulate.
    Delaware Riverkeeper I, 
    753 F.3d at 1319
     (cleaned up).
    FERC’s analysis of cumulative impacts on belugas
    complied with regulatory standards. FERC examined a wide
    variety of ongoing and planned projects that would combine
    with the Project to impact marine mammals, including belugas.
    For instance, increased ship traffic could cause more mammals
    to be hit by vessels, increased construction activity could cause
    more noise pollution, and increased air traffic could disturb
    cetaceans in particular. Nonetheless, the Commission
    concluded these cumulative effects would be minor. Moreover,
    NMFS regulates certain activities affecting marine mammals,
    7
    This provision was repealed after the agency actions at issue here.
    See Update, 85 Fed. Reg. at 43,375 (effective Sept. 14, 2020)
    (directing agencies to consider direct and indirect effects and stating,
    “[c]umulative impact, defined in 40 C.F.R. 1508.7 … is repealed”).
    17
    and this additional layer of regulation would address some of
    the Project’s impacts on belugas.
    CBD’s objections fail to demonstrate that FERC’s
    consideration was inadequate. CBD maintains FERC ignored
    or failed to understand the differences between belugas and
    other marine mammals. But the EIS repeatedly acknowledged
    and discussed these differences. CBD also suggests FERC’s
    analysis is inconsistent because it acknowledges that impacts
    on belugas could be “significant” in some circumstances and
    then concludes that cumulative impacts would be minor. The
    alleged contradiction is illusory, however, because FERC
    imposed mitigation measures to minimize the impacts it
    identified. Finally, CBD argues FERC unreasonably relied on
    NMFS regulation, even though NMFS is powerless over many
    of the environmental stressors that affect belugas. But FERC
    discussed NMFS only at the end of its detailed analysis, and it
    recognized the limited nature of NMFS’s power.
    In sum, the Commission properly assessed the cumulative
    impacts on beluga whales. CBD may disagree with the
    Commission’s policy choice to approve the Project, but the
    Commission comported with its regulatory obligations.
    E.
    CBD next argues that FERC’s evaluation of the Project’s
    impacts on wetlands was arbitrary and capricious. CBD relies
    on a difference between FERC’s estimate of the number of
    affected wetlands acres and the estimate the Corporation gave
    to the Army Corps of Engineers in a parallel permit application.
    We find that FERC reasonably acknowledged and
    addressed the difference in affected wetlands calculations.
    FERC estimated the Project would permanently affect 8,225
    acres of wetlands even after mitigation efforts. While approval
    18
    of the Project was pending before FERC, the Corporation
    applied to the Army Corps for a Clean Water Act permit to
    discharge materials into the navigable waters of the United
    States. 
    33 U.S.C. § 1344
    (a). In its permit application, the
    Corporation estimated the Project would impact 10,324 acres
    of wetlands.
    The Commission provided two explanations for the
    apparent discrepancy. First, the estimates were measuring
    different things. FERC’s calculation considered only wetlands
    proper, whereas the Corporation’s estimate included rivers,
    lakes, and bodies of saltwater. Second, FERC explained the
    estimates were based on different methods. FERC also
    consulted with the Army Corps and confirmed that over 99%
    of the gap in acreage calculation could be explained by the
    differences in scope and methodology. The Commission
    rationally accounted for the different acreage estimates, and
    CBD raises no other objection to the wetlands analysis. See
    Gulf Restoration Network, 47 F.4th at 799–800. We decline to
    second guess the Commission’s reasoned judgment in
    evaluating the impact on wetlands.
    III.
    Finally, CBD suggests the Commission’s substantive
    decision to authorize the Project was arbitrary and failed to
    satisfy the NGA. Under its delegated authority, FERC “shall
    issue” authorization for LNG facilities “unless” it determines
    doing so “will not be consistent with the public interest.”8 15
    U.S.C. § 717b(a); see also Vecinos, 6 F.4th at 1326. The NGA
    8
    The Department of Energy has delegated to FERC authority over
    the approval of LNG facilities. Department of Energy Delegation
    Order No. S1-DEL-FERC-2006, § 1.21(A) (May 16, 2006); see also
    Sierra Club v. FERC, 
    827 F.3d 59
    , 63 (D.C. Cir. 2016).
    19
    “sets out a general presumption favoring … authorization.” W.
    Va. Pub. Servs. Comm’n v. Dep’t of Energy, 
    681 F.2d 847
    , 856
    (D.C. Cir. 1982). FERC’s approval of the Project easily
    comports with the NGA. The Commission expressly concluded
    the Project was in the public interest because it would have
    substantial economic and commercial benefits, and these
    benefits were not outweighed by the projected environmental
    impacts.
    CBD asks us to set aside the Commission’s public interest
    determination on various grounds, including that the
    Commission failed to take a hard look at environmental harms;
    ignored impacts on belugas; failed to analyze the social cost of
    carbon; and did not adequately consider alternatives. In
    responding to CBD’s NEPA challenges, we have already
    explained why these arguments either fail or are not exhausted,
    and they fare no better when framed as NGA challenges.
    FERC’s public interest determination was reasonable and
    lawful.
    ***
    In approving the Alaska Liquid Natural Gas Project, the
    Commission complied with the NGA, NEPA, and the APA.
    CBD fails to provide any reason for this court to disturb the
    Commission’s reasonable determinations. To the extent the
    issues raised in the petition for review were not exhausted, we
    dismiss the petition for lack of jurisdiction. We otherwise deny
    the petition on the merits.
    So ordered.
