That's the whole point of carbon (and other Pigouvian) taxes - harness narrow self-interest into better global decision making. Badgering everyone to become a saint seems like a low-percentage plan.
What you dont get is that what "mega-dams and hydro" do on a relatively small area is what oil/gas/coal is doing on a global scale.
These oil companies are going to try survive as long as possible by a astroturfing, throw out misleading studies, bribing public officials, any means necessary to make as much money as possible. Because at the end of the day for a corporation its about making money nothing else.
What we got do is get the government to stop subsidizing oil/gas/coal. At this point we have made less then zero impact on carbon emissions. We're still going up in carbon emissions at the beginning of covid we saw a slight reduction but we're well above pre-covid levels.
The issue I see is the money that being made from oil/gas/coal is peanuts compare to the damage thats being done and the damage thats going to occur.
So when your iphone gets hacked they have every thing they need in a nice neat package to make your life hell. The more valuable you make the phone the more likely bad actors are to go after it ... I can only see bad things from this.
I'm pretty sure they didnt do this to for the benefit of the planet and more for the bottom line
