Sustainability prefix (3)

Ross

I believe the answer is:

eco

'sustainability prefix' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for eco that I've seen before include "Concerned with the environment" , "Environmental group" , "Green prefix" , "Umberto - - , novelist" , "Umberto --, Italian writer" .)

I've seen this clue in the USA Today and The Washington Post.
