"Green movements" look for a planned transition away from oil that doesn't cause worldwide economic disaster. The whole motivation is to prevent human suffering, not increase it.

That this makes you wonder indicates that you fundamentally misunderstand the entire point of environmental movements.

Further, even if there was "celebrating" how would you know? Are you involved with the groups politically working towards those ends? Perhaps you should question your information diet, rather than assuming that your information diet is representative of reality.
