    Judge Lewis A. Kaplan of the United States District Court for the Southern
    District of New York, sitting by designation.
    Plaintiffs-Appellants Natural Resources Defense Council and
    Environmental Defense Fund appeal from a judgment of the United States
    District Court for the Southern District of New York (Castel, J.). The district court
    held that the Environmental Protection Agency properly invoked the deliberative
    process privilege and Exemption 5 of the Freedom of Information Act (“FOIA”)
    to withhold a portion of its OMEGA computer program when responding to
    Plaintiffs-Appellants’ FOIA request. Because we agree with Plaintiffs-Appellants
    that the requested record is not deliberative, the judgment of the district court is
    REVERSED and the case REMANDED.

    Appellee.
    GERARD E. LYNCH, Circuit Judge:
    This appeal concerns a Freedom of Information Act (“FOIA”) request filed
    with the Environmental Protection Agency (“EPA”) by Plaintiffs-Appellants
    Natural Resources Defense Council and Environmental Defense Fund
    (collectively “NRDC”). NRDC requested release of the current version of the
    OMEGA model, an EPA computer program used to forecast the likely responses
    2
    of automakers to proposed EPA greenhouse gas emissions standards. In response
    to NRDC’s request, EPA released several components of the computer program
    but withheld one component – the so-called “core model” – under FOIA
    Exemption 5, citing the deliberative process privilege. NRDC filed suit and the
    United States District Court for the Southern District of New York (P. Kevin
    Castel, J.) held that EPA properly invoked the deliberative process privilege and
    Exemption 5. For the reasons set forth below, we agree with NRDC that the core
    model is not deliberative and therefore does not fall within the scope of the
    privilege and FOIA Exemption 5. The judgment of the district court is
    REVERSED and the case is REMANDED with directions to enter judgment for
    NRDC on its motion for summary judgment and for further proceedings
    consistent with this opinion.
    BACKGROUND
    I.    The OMEGA Model and EPA Rulemaking
    The Clean Air Act requires EPA to regulate emissions from new motor
    vehicles if EPA determines that the vehicles “cause, or contribute to, air pollution
    which may reasonably be anticipated to endanger public health or welfare.” 42
    U.S.C. § 7521(a)(1). In 2009, EPA concluded that greenhouse gas (“GHG”)
    3
    emissions from motor vehicles contribute to air pollution and climate change and
    thereby “endanger[ ] the public welfare of both current and future generations.”
    Endangerment and Cause or Contribute Findings for Greenhouse Gases Under
    Section 202(a) of the Clean Air Act, 74 Fed. Reg. 66,496, 66,498-99 (Dec. 15, 2009).
    Per its Clean Air Act mandate, EPA began regulating GHG emissions from new
    motor vehicles in 2010. See Light-Duty Vehicle Greenhouse Gas Emission
    Standards and Corporate Average Fuel Economy Standards, 75 Fed. Reg. 25,324
    (May 7, 2010).
    As EPA sets emissions standards under the Clean Air Act, the statute
    directs it to do so in consideration of the compliance costs and lead time required
    for automakers to meet the new standard. 42 U.S.C. § 7521(a)(2). Estimating these
    time and cost factors is no easy task because EPA does not prescribe the manner
    by which automakers meet a given GHG standard, instead leaving it to each
    manufacturer to select from the “almost infinite number of technology
    combinations that could produce a desired level of emissions reductions.” J.
    App’x 82 ¶9 (internal quotation marks omitted). And since each technology
    combination has its own price tag and lead time requirements, coming up with
    viable, industry-wide estimates for these statutory factors is a complex
    4
    undertaking. To sift through the multitude of ways in which each automaker
    could comply with a GHG standard to identify the most likely compliance
    decisions, EPA developed a computer program called the Optimization Model
    for Reducing Emissions of Greenhouse Gases from Automobiles (“OMEGA” or
    “the OMEGA model”). See 75 Fed. Reg. at 25,446.
    The OMEGA model simulates how automakers will likely react to a
    hypothetical GHG standard. Based on scenario data loaded into the model,
    OMEGA forecasts “which emissions-reducing technologies manufacturers will
    use, when they will incorporate those technologies into each of their vehicles, and
    how much those technologies will cost to apply.” J. App’x 76 ¶18. With the
    OMEGA projections in hand, EPA is better able to set a GHG emissions standard
    that protects public health and welfare while remaining cognizant of the time and
    cost burdens imposed on automakers. As described in greater detail below, the
    OMEGA model consists of five key components. This appeal concerns only one
    of these components: the core model.
    EPA has relied on the OMEGA model to inform its GHG standards since it
    started regulating emissions in 2010. See 75 Fed. Reg. at 25,446. Since then, EPA
    has publicly released then-current versions of OMEGA alongside technical
    5
    reports, proposed rules, and final rules, anticipating that the public would be
    most interested in using OMEGA at those times. In total, EPA has released five
    versions of the OMEGA model over the past decade. In addition to these public
    releases, EPA’s historic practice was to freely share the most current version of
    OMEGA upon request.
    In 2012, EPA set GHG emissions standards for vehicles with model years
    (“MY”) 2017-2025. See 2017 and Later Model Year Light-Duty Vehicle
    Greenhouse Gas Emissions and Corporate Average Fuel Economy Standards, 77
    Fed. Reg. 62,624, 62,627 (Oct. 15, 2012). Recognizing the long time frame of the
    rule and the likelihood of intervening technological advancements, the 2012 rule
    required EPA to conduct a mid-term evaluation by April 2018 to ensure that the
    GHG standards set for MY 2022-2025 continued to be appropriate.
    Id. at 62,784.
    When EPA carried out the evaluation, it determined that the GHG standards set
    for MY 2022-2025 were based on overly optimistic assumptions and were
    therefore too stringent. See Mid-Term Evaluation of Greenhouse Gas Emissions
    6
    Standards for Model Year 2022-2025 Light-Duty Vehicles, 83 Fed. Reg. 16,077,
    16,087 (Apr. 13, 2018).1
    In August 2018, EPA issued a notice of proposed rulemaking that
    recommended freezing the GHG emissions standards at MY 2020 levels for MY
    2021-2026. See The Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule for Model
    Years 2021-2026 Passenger Cars and Light Trucks, 83 Fed. Reg. 42,986, 42,988
    (Aug. 24, 2018). As with previous GHG emissions rules, the 2018 proposed rule
    was issued as a joint rulemaking between EPA and the National Highway Traffic
    Safety Administration (“NHTSA”). Unlike previous rules, however, EPA did not
    base its proposal on the OMEGA model’s projection of automaker compliance,
    instead relying on a NHTSA modeling program.
    Id. at 43,000.2
    1
    The April 2018 evaluation was actually the second mid-term evaluation. In
    January 2017, EPA concluded that the existing GHG standards remained
    appropriate, but EPA announced its intention to reconsider that evaluation in
    March 2017. See 83 Fed. Reg. at 16,078.
    2
    The record shows that approximately four months before the proposed rule was
    issued, EPA met with the Office of Management and Budget to express serious
    concerns about the results produced by the NHTSA model, including concerns
    that the model was consistently overestimating compliance costs and not
    prioritizing cost-effective technologies. Notwithstanding EPA’s initial concerns,
    the NHTSA model was ultimately used to inform the GHG standards in the 2018
    proposed rule.
    7
    II.   Procedural History
    In August 2018, NRDC submitted a FOIA request to EPA, seeking several
    records related to OMEGA, including all unreleased versions of the model itself.
    EPA did not respond within the statutory deadline and NRDC filed suit.
    While the litigation was pending, NRDC voluntarily narrowed its request
    to seek only four of the five components of the current version of the OMEGA
    model, version 1.4.59. EPA then released three of the components of OMEGA
    v.1.4.59. EPA withheld release of the fourth component, the core model for
    OMEGA v.1.4.59, on the grounds that it was protected by the deliberative process
    privilege and thus within the scope of FOIA Exemption 5.
    NRDC and EPA filed cross-motions for summary judgment on the issue of
    whether EPA properly withheld the OMEGA core model. The district court
    granted summary judgment for EPA.
    DISCUSSION
    “We review a district court’s grant of summary judgment in FOIA
    litigation de novo.”ACLU v. Nat’l Sec. Agency, 
    925 F.3d 576
    , 588 (2d Cir. 2019). In
    enacting FOIA, Congress “intended to establish a general philosophy of full
    agency disclosure.” Fed. Labor Relations Auth. v. U.S. Dep’t of Veterans Affairs, 958
    
    8 F.2d 503
    , 508 (2d Cir. 1992) (internal quotation marks omitted). FOIA thus
    requires an agency to “disclose records on request, unless they fall within one of
    nine exemptions.” Milner v. Dep’t of the Navy, 
    562 U.S. 562
    , 565 (2011). “[I]n a
    FOIA case, the defending agency has the burden of showing . . . that any
    withheld documents fall within an exemption to the FOIA.” Carney v. U.S. Dep’t
    of Justice, 
    19 F.3d 807
    , 812 (2d Cir. 1994).
    Here, EPA has invoked Exemption 5, which provides that agencies need
    not release “inter-agency or intra-agency memorandums or letters that would not
    be available by law to a party other than an agency in litigation with the agency.”
    5 U.S.C. § 552(b)(5). By this language, Congress incorporated civil discovery
    privileges into Exemption 5, allowing an agency to withhold records that would
    be privileged in litigation. Dep’t of the Interior v. Klamath Water Users Protective
    Ass’n, 
    532 U.S. 1
    , 8 (2001). The specific discovery privilege invoked by EPA to
    justify withholding the OMEGA core model is the deliberative process privilege.
    That privilege is designed “to enhance the quality of agency decisions by
    protecting open and frank discussion among those who make them within the
    Government.”
    Id. at 9
    (internal quotation marks omitted). Accordingly, the
    9
    privilege covers certain agency records reflecting internal advisory opinions,
    recommendations, and deliberations.
    In order for the privilege to apply, the agency record at issue must be (1) an
    inter-agency or intra-agency memorandum or letter; (2) pre-decisional; and (3)
    deliberative. See Tigue v. U.S. Dep’t of Justice, 
    312 F.3d 70
    , 76 (2d Cir. 2002). NRDC
    argues that the OMEGA core model does not meet any of these three
    requirements, and that each offers an independent basis for reversing the district
    court. Because we agree that the OMEGA core model is not deliberative, we
    resolve this appeal on that ground alone.3
    I.    The Function and Context of the Core Model
    “Whether [the core model] is exempt under (b)(5) depends not only on the
    intrinsic character of the [core model] itself, but also on the role it play[s] in the
    administrative process.” Lead Indus. Ass’n, Inc. v. Occupational Safety and Health
    Admin., 
    610 F.2d 70
    , 80 (2d Cir. 1979). We thus begin by describing both the core
    model and its role within the broader OMEGA context. Both EPA and NRDC
    3
    We further decline to address NRDC’s additional arguments regarding the
    segregability of the OMEGA model machine code and the foreseeable harm
    requirement of 5 U.S.C. § 552(a)(8)(A)(i)(I) because resolving those issues is also
    not necessary to resolve this case.
    10
    submitted declarations detailing the workings of the OMEGA model, and these
    declarations are largely consistent in their depictions.4 While the NRDC
    declarations are somewhat more detailed, EPA did not dispute their accuracy
    before the district court and does not do so before us on appeal. We draw on this
    undisputed factual record to form our understanding of the core model and its
    context within OMEGA.
    Each “run” of the OMEGA model involves five components or stages. In
    the first component, input data is loaded into the model. The inputs are Excel
    spreadsheets filled with raw data that establish the factors and constraints to be
    modeled in that run of OMEGA. These inputs include (1) market data, including
    the characteristics of the vehicles at issue and current emissions levels; (2)
    technology data, such as the available emissions-reduction options and their
    4
    EPA submitted declarations from William L. Wehrum, the then-assistant
    administrator for the EPA Office of Air and Radiation (“OAR”); and William
    Charmley, the director of the Assessment and Standards Division within the EPA
    Office of Transportation and Air Quality (“OTAQ”), which falls under OAR.
    NRDC submitted declarations from Margo Oge, the former director of OTAQ;
    Nicholas Lutsey, a program director at the International Council on Clean
    Transportation; and Dave Cooke, a senior vehicles analyst at the Union of
    Concerned Scientists.
    11
    costs; (3) scenario data, primarily the GHG standard being modeled; and (4)
    other data relevant to the projection, such as anticipated fuel prices.
    Once the input files have been loaded, the second component takes over. A
    series of pre-processors take the raw input data and organize it into datasets to
    facilitate the modeling. For example, one pre-processor groups together
    technologies that might commonly be implemented together while another
    accounts for emissions-reduction technologies already in use to avoid double-
    counting.
    The third component is the core model, which consists of a series of
    algorithms, written in the C# computer programming language. These
    algorithms “run thousands of calculations” on the processed input data to
    forecast the emissions-reduction technologies automakers would likely
    incorporate to meet the simulated GHG standard in the particular scenario
    created by the input data. J. App’x 131 ¶13. The core model begins by
    “determin[ing] the specific emission standard applicable for each manufacturer
    and its vehicle class (car or truck). Then the model determines the emission
    standard applicable to each manufacturer’s car and truck sales.”
    Id. at 87
    ¶20.
    With the emissions goals identified from the input data, the core model
    12
    “considers the range of technology packages available to each automaker’s
    individual vehicles” and applies different combinations of the available
    technologies to an automaker’s fleet until it meets the simulated GHG standard
    in the most cost-effective way possible.
    Id. at 131
    ¶11.
    The core model results are turned into a series of output Excel files, the
    fourth component of OMEGA.5 The outputs detail the technologies automakers
    are projected to deploy as well as the costs of compliance. In the final component,
    the raw output data is put through a series of post-processors, which organize
    the results into a more user-friendly format and provide additional analysis. EPA
    can then review the results of the run to get a sense of the compliance time and
    costs likely to be associated with the simulated scenario.
    II.   The Core Model Is Not Deliberative
    Upon our review of OMEGA in general and the core model in particular,
    we are persuaded that the core model is not deliberative. An agency record is
    “deliberative if it reflects the give-and-take of the consultative process.” Brennan
    Ctr. for Justice at N.Y.U. Sch. of Law v. U.S. Dep’t of Justice, 
    697 F.3d 184
    , 202 (2d
    5
    NRDC has not sought release of these raw data output files; the FOIA request at
    issue seeks only the other four components.
    13
    Cir. 2012) (internal quotation marks omitted). “[T]he privilege focus[es] on
    documents reflecting advisory opinions, recommendations and deliberations
    comprising part of a process by which governmental decisions and policies are
    formulated.” Grand Cent. P’ship, Inc. v. Cuomo, 
    166 F.3d 473
    , 482 (2d Cir. 1999)
    (internal quotation marks omitted).
    Here, the record shows that to the extent the full OMEGA model reflects
    any subjective agency views, it does so in the input files, not the core model. See J.
    App’x 85 ¶13, 86 ¶¶15-16, 130 ¶10(a), 131 ¶12. It is the inputs that determine the
    constraints, predictions, and goals for each run of OMEGA. As one declarant
    explained, “[v]ery few numeric values are hard-coded in the pre- and post-
    processors or the [core model], as the model is meant to be built upon the input-
    file technology and cost data and the externally determined GHG-emission
    target.”
    Id. at 88
    ¶22. Once the input files set the parameters of the simulation, the
    only task remaining for the core model is to run “thousands of calculations” on
    the given data so as to find the most cost-effective technology combinations for
    that particular scenario.
    Id. at 87
    ¶20; see
    id. at 75
    ¶16 (“[T]he OMEGA model and
    its outputs simply reflect the inputs fed into the model, and EPA uses different
    sets of inputs to reflect different scenarios.”). The core model is thus akin to a
    14
    specialized calculator, driven by the same algorithms to make the same
    calculations on every run of OMEGA. And the release of “materials relating to
    standard or routine computations or measurements over which the agency has
    no significant discretion[] is unlikely to diminish officials’ candor or otherwise
    injure the quality of agency decisions.” Petroleum Info. Corp. v. U.S. Dep’t of the
    Interior, 
    976 F.2d 1429
    , 1436 (D.C. Cir. 1992).
    EPA argues that the deliberative process privilege may properly be applied
    to records that are ostensibly objective or fact-based insofar as such records might
    reveal the agency’s decisionmaking process. While the privilege generally does
    not extend to factual material, “[i]f the factual materials are inextricably
    intertwined with policy making recommendations so that their disclosure would
    compromise the confidentiality of deliberative information[, they are] entitled to
    protection under Exemption 5.” Lead Indus. 
    Ass’n, 610 F.2d at 85
    (internal
    quotation marks omitted). Specifically, EPA contends that release of the core
    model would reveal the agency’s decision to include or exclude various
    analytical tools, thus exposing agency thinking about the need for “a different or
    more substantial type of analysis in a certain area.” J. App’x 123 ¶12. As an
    example, EPA points to its deliberations about adding a “consumer choice sub-
    15
    model” to OMEGA, which would allow the model to account for anticipated
    consumer responses to changes in fuel economy and pricing.
    Id. at 124
    ¶¶18-19.
    EPA claims that “[t]he mere fact of whether or not policy consideration was
    given to including such an analytical tool in the current version of the OMEGA
    model, and the outlines and parameters of any such hypothetical tool, would
    reveal EPA’s pre-decisional thinking about the role of consumer choice in the
    regulatory development process.”
    Id. at 124
    ¶19.
    EPA’s argument stretches the deliberative process privilege too far. The
    release of the core model could, at most, reveal the various analytical tools EPA
    has at its disposal. It would not explain the factors that prompted development of
    a tool, nor would it expose rationales cutting against or in favor of its use. “Even
    the most mundane material could be said to reflect the exercise of agency
    discretion in some sense . . . . To be protected under Exemption 5, the kind and
    scope of discretion involved must be of such significance that disclosure
    genuinely could be thought likely to diminish the candor of agency deliberations
    in the future.” Petroleum Info. 
    Corp., 976 F.2d at 1436
    n.8.
    The example of the consumer choice sub-model is particularly unhelpful to
    EPA’s argument, as the record shows that the last publicly released version of the
    16
    OMEGA core model contained the consumer choice sub-model notwithstanding
    the fact that EPA had not – and still has not – “turned on” the sub-model to
    actually use it in OMEGA’s analysis. See J. App’x 185 ¶10, 186 ¶14. Thus, not only
    does the inclusion of a new analytical tool in the core model fail to reveal the
    deliberations underlying the tool’s development but it may not even reveal
    whether EPA has decided to use that tool. Without more, the fact that the core
    model might reveal that EPA has developed a new analytical capacity for
    OMEGA – which the agency may or may not be using – does not make the core
    model deliberative.6
    The core model is distinct from the computer programs at issue in two
    district court cases on which EPA relies. In Cleary, Gottlieb, Steen & Hamilton v.
    Department of Health and Human Services, 
    844 F. Supp. 770
    (D.D.C. 1993), the
    district court held that computer programs used to conduct an epidemiological
    study were deliberative.
    Id. at 782-83.
    In that case, the author of the study testified
    6
    EPA’s argument that disclosure of the core model would reveal privileged
    deliberations is further undermined by record evidence showing that the
    deliberations EPA claims to protect have already been revealed in the input files
    released to NRDC. See, e.g., J. App’x 185 ¶¶11-12, 186 ¶14 (explaining that the
    released input files contain data inputs for the consumer choice sub-model as
    well as the “on/off” switch to deploy the sub-model, which is set in the “off”
    position).
    17
    that she regularly modified her software over the course of the study to reflect
    her evolving hypotheses. The court found that the programs thus “reflect[ed]
    their creator’s mental processes” and revealed her “scientific deliberations and
    opinions.”
    Id. at 783.
    In contrast, the core model provides only highly abstract
    insights into EPA deliberations, which are too far removed from any policy
    judgments to render the core model deliberative. Moreover, the core model does
    not involve “culling and selection of relevant facts” in the same sense as the
    Cleary computer program.
    Id. And in
    Goodrich Corp. v. U.S. EPA, 
    593 F. Supp. 2d 184
    (D.D.C. 2009), the district court held that an incomplete computer modeling
    program was deliberative because the model was “still in development,”
    id. at 187,
    and was thus akin to a “draft,”
    id. at 189.
    We take no position on whether the
    core model of OMEGA v. 1.4.59 may in some sense be considered a “draft”
    because, as explained above, any insight that could be gleaned by comparing the
    current core model to other versions is simply not the kind of “policy-oriented
    judgment” protected by the deliberative process privilege. Nat’l Sec. Archive v.
    18
    CIA, 
    752 F.3d 460
    , 465 (D.C. Cir. 2014) (emphasis and internal quotation marks
    omitted).7
    The “key question” we keep in mind when assessing the application of the
    deliberative process privilege to an agency record is “whether disclosure would
    tend to diminish candor within an agency.” Petroleum Info. 
    Corp., 976 F.2d at 1435
    (internal quotation marks omitted). The core model does not contain or expose
    the types of internal agency communications that courts typically recognize as
    posing a risk to the candor of agency discussion such as advice, opinions, or
    recommendations. See Grand Cent. 
    P’ship, 166 F.3d at 482
    . Instead, it contains
    algorithms instructing the model on how to process the input data. While the
    core model may in some respects reflect internal agency deliberations, disclosure
    of its analytical tools cannot reasonably be anticipated to impair the quality of
    agency decisionmaking. See 
    Tigue, 312 F.3d at 76
    . Here, like the D.C. Circuit in
    Petroleum Information Corp., “[w]e do not see in the data elements, codes, and
    7
    Similarly, we in no way suggest that a computer program or set of algorithms
    may not, under particular circumstances, come within the deliberative process
    privilege. Algorithms underlying computer programs may well reflect policy
    judgments or assumptions about what data is relevant to a policy determination
    or factual projection. We hold only that on the record of this case, EPA has not
    presented sufficient evidence to permit a conclusion that the core model of
    OMEGA is deliberative.

    format choices, to the extent they have been explained to us, the candid or
    personal decisions that, if revealed prematurely, would be likely to stifle honest
    and frank communication within the 
    agency.” 976 F.2d at 1438-39
    (internal
    quotation marks omitted).
    Under FOIA, “[a]n agency must disclose agency records . . . unless they
    may be withheld pursuant to one of the nine enumerated exemptions.” U.S. Dep’t
    of Justice v. Tax Analysts, 
    492 U.S. 136
    , 150-51 (1989) (internal quotation marks
    omitted). Because the OMEGA core model is not deliberative, it does not fall
    within the scope of the deliberative process privilege. Accordingly, its
    withholding under Exemption 5 was improper.
    CONCLUSION
    For the reasons stated above, we find that the district court erred in
    granting summary judgment to EPA and in denying summary judgment to
    NRDC. The judgment of the district court is therefore REVERSED and the case is
    REMANDED with directions to enter judgment for NRDC on its motion for
    summary judgment and for further proceedings consistent with this opinion.
