they imagined a solution would pop up where they themselves would not be required to make sacrifices

Exactly what's happening in Canada with the carbon tax. If you emit more CO2 than the average you pay a tax. If you emit less you get a rebate. But, now people who emit more than the average think that their case is special and they shouldn't have to make a sacrifice because they're not the real problem.

they imply that corporations emit greenhouse gases totally decoupled from the people’s consumption

Yes! Or, they think that corporations are maliciously burning fossil fuels for the hell of it. While corporations might not care about the environment, they do care about profits. They will burn oil to make profits, but if they can find a way to burn less oil and use that to make more profits, they'll do that too. Now, sure they'll also burn more oil if they can make a business case to do it. But, unless you're talking entertainment companies like Las Vegas casinos, corporations are generally not burning oil just for the hell of it.
