Cory Tyrone Robinson, Sr., federal prisoner # 56493-180, has moved to proceed in forma pauperis (IFP) in this appeal of the denial of his motion for a sentencing reduction under 18 U.S.C. § 3582(c)(2). The district court denied Robinson leave to appeal IFP, but it did not certify that his appeal was not taken in good faith. See Fed. R.App. P. 24(a). We may nevertheless dismiss the appeal sua sponte pursuant to 5th Cir. R. 42.2 if it is apparent that the appeal lacks merit.

Robinson argues that the district court abused its discretion in denying his motion for a sentencing reduction because it failed to consider 18 U.S.C. § 3553(a)(6), which concerns the need to avoid unwarranted sentencing disparities, and placed too great a weight on his criminal history. Robinson’s unwarranted-disparity argument is without merit because it amounts to a request that the court make a sentencing reduction mandatory when requested pursuant to the crack cocaine amendments. United States v. Smith, 595 F.3d 1322, 1323 (5th Cir.), cert. denied, — U.S. -, 130 S.Ct. 3374, 176 L.Ed.2d 1260 (2010). The district court provided reasons for denying Robinson’s motion that reflect its consideration of the § 3553(a) *357 factors. See United States v. Cooley, 590 F.3d 293, 297-98 (5th Cir. 2009); United States v. Whitebird, 55 F.3d 1007, 1010 (5th Cir. 1995). Robinson’s effort to have us weigh the factors anew is unavailing.

Robinson has not shown that the denial of his § 3582(c)(2) motion presents a non-frivolous issue for appeal. Accordingly, his motion for leave to proceed IFP is denied, and his appeal is dismissed. 5th Cir. R. 42.2.

MOTION DENIED; APPEAL DISMISSED.
