An A319 pilot reported an actual fuel burn 1;300 pounds over planned burn even when published fuel conservation procedures in place. Dispatch is not using actual fuel burns to flight plan.

Narrative:
Aircraft was fueled to destination with a fuel burn of 25;800 pounds of fuel. The actual burn was 27;100 pounds. That is a 1;300 over burn as calculated from takeoff to touch down. This is documented in the mcdu post flight report. We made every effort to comply with the flight plan and altitude step climbs. At mid point we had a 400 pound under burn. The greatest error in the burn was from top of climb to touch down. ATC gave use directs that shortened our arrive procedure and all publish decent were complied with. There was no weather consideration at the destination. Although the required fuel contained 1;500 pound of contingency fuel this does not relieve dispatch from calculating an accurate destination fuel burn. Dispatch is not using realistic fuel burn for decent at airports with standard decent profiles. Use mcdu fuel burn data to establish standard decent burn for all airports. Dispatch has the ability to gather this data directly from the mcdu via atsu (air traffic services unit) or required crews to print the post flight fuel burn report.
