as you can see in the comment I was replying to, discussions of emissions always get derailed by putting responsibility on corporations when faced with the prospect of changing their own lifestyle to lower emissions. But the emissions people want corporations to take responsibility for are the same emissions coming out of their own tailpipes, and I dont mean that figuratively. An oil corporation isnt just pumping emissions into the air at the drill site, or the pipeline, or the corporate office. When researchers are talking about carbon footprint of oil companies, they’re literally talking about the co2 emitted from the process which is at the end point, your vehicle.
There is no world where responsibility is taken for emissions that doesnt cut off access to these high emissions products and services to people, either by corporations no longer providing it, or people no longer buying it, it doesnt matter which side you blame, you dont get to keep driving a gas vehicle, eat red meat, or use non-renewable electricity.
