Narrative:
During climb out from ZZZ; passing 12000 ft; we noticed a slow drop of the left engine EPR gauge. As we climbed higher; the drop continued. At FL200; we realized the thrust had degraded enough that we could not climb to our assigned altitude of FL220. We declared an emergency for loss of thrust. The left engine stabilized at a reduced thrust setting. The right engine remained normal. By this time we were close to ZZZ1. ATC cleared us direct to ZZZ1. Approach cleared us straight to runway xr. The landing was normal; except for the left engine putting out a reduced amount of thrust.

Narrative: DURING CLBOUT FROM ZZZ; PASSING 12000 FT; WE NOTICED A SLOW DROP OF THE L ENG EPR GAUGE. AS WE CLBED HIGHER; THE DROP CONTINUED. AT FL200; WE REALIZED THE THRUST HAD DEGRADED ENOUGH THAT WE COULD NOT CLB TO OUR ASSIGNED ALT OF FL220. WE DECLARED AN EMER FOR LOSS OF THRUST. THE L ENG STABILIZED AT A REDUCED THRUST SETTING. THE R ENG REMAINED NORMAL. BY THIS TIME WE WERE CLOSE TO ZZZ1. ATC CLRED US DIRECT TO ZZZ1. APCH CLRED US STRAIGHT TO RWY XR. THE LNDG WAS NORMAL; EXCEPT FOR THE L ENG PUTTING OUT A REDUCED AMOUNT OF THRUST.
