They wouldn't be mandating reduced thrust take offs if there wasn't a significant savings on fuel consumption.

The copilot who selected maximum power for his DC8 at JFK last week, and thus was able to climb over a 767 sitting on the runway (wrong turn!), sure profited from his decision. If you are at full throttle, and keep the speed well above stall, I would be surprised if there is much difference in fuel consumption to climb to a given altitude between one safe rate of climb and another. Noise control requires maximum safe climb from some runways at some airports. It has often seemed to me that DC9's climb at higher angles than most jets. The 757 is reputed to be the most overpowered commercial plane, but we don't get many around here.
