I dont know if this is the right place to put this but does anyone know why there is a green cloverleaf on the nacelle of SAS 737's....have to find out why for a project so if someone could tell me soon that would be appreciated.

Cheers JB

SAS were the first operators of a CFM modified combustor which produced a significant reduction in the Nox output from the engine. This green symbol comes from this. (Sorry thats all I know. Try Flight archives from the B737-600 introduction.)
