for sure, titles help focus. Unfortunately, that’s now more bad focus than good focus… when a title has reached a stage where it makes people wince when they hear it, their focus is more often on avoiding or even worse, attacking the principles.
‘sustainable’ seems better all round for the time being (although, it has connotations of stagnation)… let’s just forget ‘green’, I don’t think I’ve used it in any professional context since about 1997 anyway.
