Here is the story:
there are three main form of commitements in agreemnts on emissions. they are:
uniform base level intencity;
identical percentage cuts over existing emissions;
non-uniform percentage cuts over existing emissions.

Can you translate these three?

(my version, but i'm not really shure about it:
edinyi bazovyi uroven intensivnosti;
procentnoe sokrashenie identichnoe sushestvujushim vybrosam;
neodnorodnoe procentnoe sokrashenie suschestvujushih vybrosov.)

Help, pls
