I know you're taking the piss but I worked for a Shell subsidiary for 2 years very recently and they actually take all the "green" stuff very seriously despite the fact their core business accounts for 2% of global co2 emissions. It's very bizarre and much of the internal "greenwashing" dialog reads like a catholic confessional.

With that out of the way there is a difference between corporate PR greenwashing and literally changing battery chemistries to not contain as many rare earth minerals.
