I think there's growing interest in investing in enterprises that people can feel good about, so that creates an incentive to give people something to feel good about with GM so they'll buy that stock. There are entire funds devoted to sustainability, etc. so GM has probably researched what it would take to get on some of those funds' green lists, because that triggers those funds' managers to buy their stock.
It's fun to pretend you're friendly to sell your stock.
