We write briefly to clarify that (1) the record must unambiguously demonstrate that the District Court was aware of “its discretion to consider that [the disparity between cocaine base and cocaine powder offenses in the United States Sentencing Guidelines] might result in a sentence greater than necessary,” in order to avoid a remand pursuant to
United States v. Regalado,
BACKGROUND
Defendant-appellant Robin Keller appeals from a judgment of conviction of the United States District Court for the District of Vermont (William K. Sessions, Chief Judge). She pleaded guilty to conspiracy to possess and distribute fifty grams or more of cocaine base, or “crack,” in violation of 21 U.S.C. §§ 846 and 841(a), a charge which carried a ten-year mandatory minimum, see 21 U.S.C. 841(b)(1)(A).
Sentencing in the District Court
Defendant was sentenced on July 25, 2007. At sentencing, the District Court determined that the applicable Guidelines range was 360 months’ to life imprisonment, 1 but the Court agreed to impose a non-Guidelines sentence, consistent with the recommendation contained in the plea agreement. After considering the testimony of various witnesses and the parties’ arguments, the Court stated that it had “balance[d] all of those factors, to determine a sentence which is according to 18 U.S.C. § 3553(a) ... sufficiently long to satisfy the purposes of sentencing, but not overly long.” It reviewed each of the factors in turn, along with the evidence it considered most relevant. The Court then announced that it would “depart to criminal history category five, offense level 31, [resulting in a sentencing range of] 168 to 210 months.” This calculation was based, in part, on a two-level reduction to reflect the then-forthcoming changes in the Sentencing Guidelines for offenses associated with crack cocaine. The District Court explained the basis for the two-level reduction:
[T]he reason I do that, quite frankly, is because if the Sentencing Commission were ever to determine that the crack adjustment of two levels was to be applied retroactively, then we would have to come back for a new sentencing, but, in this particular case, I am already taking that into consideration so there would be no need to apply a retroactive application of the adjustment in the *99 guidelines because it basically is a factor.
The parties did not raise the specific issue of the Court’s discretion to consider the crack-powder cocaine disparity under § 3553(a). The Court did not itself acknowledge its discretion to consider the crack-powder cocaine disparity as a basis for imposing a non-Guidelines sentence-even though it did recognize that forthcoming changes to the Guidelines somewhat mitigated that disparity — nor did it mention any pending cases in which such a theory was pressed, such as
Kimbrough v. United States,
— U.S. -,
Legal Background
At the time that the District Court sentenced defendant, the law of our Circuit did not acknowledge a district court’s so-called “variance discretion” with respect to whether the quantity disparity between crack and powder cocaine set forth in the Guidelines — a 100-to-l crack-powder ratiO' — results in an unfair measure of the seriousness of the offense.

See, e.g., United States v. Jones,
Following
Kimbrough,
our Court set forth principles for addressing appeals, such as this one, that were pending at the
*100
time
Kimbrough
was decided.
See Regalado,
On appeal, defendant argues that (1) the District Court erred by sentencing her “under the guidelines with a downward departure after determining that a non-guidelines sentence was appropriate”; and (2) we should remand the cause for resen-tencing pursuant to our decision in
Regala-do,
DISCUSSION
We review a district court’s imposition of a particular sentence for procedural and substantive reasonableness, which is akin to review under an abuse-of-discretion standard.
See Gall,
As an initial matter, we reject defendant’s contention that the District Court erred by agreeing to impose a non-Guidelines sentence and then imposing a sentence that “is really just an eight level departure within the guidelines sentencing scheme.” Appellant’s Br. at 6. In essence, she contends that the District Court stated that it would grant a variance from the Guidelines regime but then merely granted her a downward departure instead. While the record shows that the District Court used both “departure” and “non-[G]uide-line[s] sentence” to describe the sentence it imposed, it is also clear from the record that the District Court relied on its power under § 3553(a) — and not on any Guidelines provision — as a basis for the seven-level “departure.” We see no error whatsoever in the District Court’s use of the framework and terminology of the Guidelines in the course of exercising its variance discretion. To the contrary, we have said that in order to comply with
Booker,
*101
Defendant’s second argument— that a remand pursuant to
Regalado
is required — raises the recurring issue of how we will determine whether a district court understood its variance discretion, which was recognized by the Supreme Court in
Kimbrough,
The Government points to various indications in the record and outside the record of Chief Judge Sessions’s awareness of his “variance discretion,” but these fall short of an explicit statement by the sentencing court that it was aware of its discretion to impose a lighter sentence but declined to do so. Accordingly, the Government suggests that remanding the case to the District Court pursuant to
Regalado
under these circumstances would be tantamount to imposing a requirement that a district court must explicitly state that it was aware of its variance discretion. The Government instead presses the view that we should not regard a district court’s silence on the issue of the crack-powder disparity as indicating that the court “was unaware of [its]
potential
authority to depart from the advisory Guidelines range based on that disparity” (emphasis added). Appellee’s Supplemental Br. of 7/8/08 at 4. We have disavowed formulaic requirements,
see Crosby,
We cannot, however, adopt the Government’s theory that where a record is silent on the district court’s understanding of its variance discretion, we can nevertheless assume that the court understood its various sentencing options.
See Regalado,
In evaluating whether a
Regalado
remand is appropriate, we consider the evidence in the record, such as the sentencing transcript and the parties’ submissions. The strongest evidence of this kind presented by the Government is the fact that the District Court explicitly accounted for the then-pending changes to the crack Guidelines in the course of imposing a
non-
Guidelines sentence. While this may suggest that the Court was aware of (1) its discretion generally to depart from the Guidelines and (2) the pending changes to the Guidelines’ treatment of crack cocaine, the record does not establish that the Court was aware of its authority to impose a non-Guidelines sentence because of a disagreement with the policy underlying the crack-powder disparity in the Guidelines. Indeed, these possible indications of the District Court’s understanding cannot surmount the fact that, as of the date defendant was sentenced, the District Court was bound by our holding in
Castillo
that it did not have this discretion.
See Castillo,
CONCLUSION
For the reasons stated above, the judgment is AFFIRMED and the cause REMANDED for consideration of whether resentencing is appropriate pursuant to
Regalado,
Notes
. The District Court's findings were consistent with the recommendations contained in the Pre-Sentence Report ("PSR”), based on the following calculations. The defendant’s base offense level was 38 as a result of the weight of crack involved in the offense. See U.S.S.G § 2D1.1 (c)(1). The PSR added a four-level role enhancement pursuant to section 3Bl.l(a) and deducted three levels for acceptance of responsibility, see id. § 3 El.l. Defendant's criminal history placed her in Category V.
. While the terms "departure” and "variance” are often used interchangeably to describe deviations from the recommended Guideline range,
see, e.g., Gall v. United States,
552 U.S.-,
. A passing mention in a footnote in
United States v. Regalado
may appear to leave open the possibility that such an explicit statement is required.
See
This appeal presents an additional wrinkle because on a Crosby remand — where the issue is whether the sentencing judge would have imposed a non-trivially different sentence had it anticipated Booker — there would have been no occasion for the Court to consider the harshness of the 100-to-l ratio. Even if the court did consider this issue, it would not have had to say so explicitly.
Id. (emphasis added). While this statement could be read to imply that after Kimbrough an explicit statement was required, it is merely an explanation for why remand was appropriate in that case although the district court could have considered the ratio on the Crosby remand. Regalado did not impose an explicit statement requirement.
. Chief Judge Sessions's statements at a sentencing hearing for defendants in a different case several months after he sentenced Keller cannot demonstrate his awareness of his discretion at the time Keller was sentenced. Similarly, we cannot place any weight on Chief Judge Sessions's likely personal knowledge of sentencing issues, because of his service as Vice Chair of the United States Sentencing Commission, as a basis for concluding that he was aware of his discretion to depart in order to account for the crack-powder disparity. An inference on this basis would be speculative at best.
