It is your central heating, my car, her holiday in the Seychelles, his concrete flooring.....
None of these things is the fault of capitalism, regulated or otherwise. All of us have lifestyles, which we have chosen for ourselves, that create the problem.
What I object to is this business of "othering" the problem, as if it is nothing to do with virtuous Guardian readers. This is just the Leftie version of the denial of responsibility we all see on the Right.
Apart from the hypocrisy, I think it is a huge mistake to try to connect blame for the climate crisis with politics. All that does is make others think it is just another political cause, peddled by the same people they have always disagreed with about politics. That is not the way to get people on board and, even worse, it implies the solution requires some kind of radical change to our economic system, pushing the solution way out into never-never-land, instead of buckling down and getting on with it.
