1 persons individual change is not enough to matter. For individual carbon footprint changes to matter you need 100% participation across the planet to fix a small part of the problem.
To make systemic change you need the majority of voters. So around 25% participation to fix 100% of the problem.
I provided my source showing BP hired a marketing firm to get the public to focus on their individual carbon footprint.
So to answer your question of who the shill is: I’d say the person repeating the fossil fuel talking points.
