I feel like this point is missing the big picture: people create the demand, and companies supply what the market demands. Like or hate "the free market", this is essentially what it is. If there were magically 1/10th the number of humans on the planet, we would expect those companies to have 90% less emissions. It's not that some of these companies aren't bad actors, and have actions that are at times immoral, it's that they are amoral actors in a market economy that is only responsive to consumer demand.

The example I like to give is that companies' race to the bottom on quality. They're responding to human behavior, where if an item on Amazon is $6, and another very similar item is 10 cents cheaper, the cheaper item will sell 100x more. This is a brutal, cutthroat example of human behavior and market forces. It leads to shitty products because consumers are more responsive to price and find it hard to distinguish quality, so the market supplies superficially-passable junk at the lowest possible price and the lowest possible profit margin.
