And big corporations are steered by money nobles (or oligarchs, whatever you want to call them). They set the agenda of the corporations thanks to the money they invest into them by owning their shares or being directly invested.
Sadly nothing will change until the common people start to realize that you have to remove those oppressors, who not only steer corporations but also influence public opinion through media and agencies, change policies as they need by buying out politicians, etc.
Be it peacefully or violently.
Oh, and by the way, it's not just the climate that is affected by their quest of greed. Poverty, wars, low education, bad healthcare and so much more are also heavily influenced, if not entirely caused by them and their shenanigans.
