Manager deliberately trying to rile me up?

Ignore him. The offenses you described are too minor for you to do anything about. Ignore him until he does something that constitutes harment and then complain. Calling you a tree hugger isn't even an insult. Driving a giant SUV is not harment. He might be the worst polluter in the world, and might flaunt in to you, but that is not harment. Just take his silly behavior and wait. And keep up the good work. You are making friends and he is letting everyone know he is a fool.
