Yes, this is correct. And the reason is because our capitalist classes have decided that it is not sufficiently profitable, so they're not going to do it.
We must understand this reality. Capital *cannot* be relied upon to address the climate crisis.

Ahead of COP 30 I’ve been thinking about the irony that the critics of our 1.5 IPCC report are many of the people now saying it’s too late to act because we’ve going past 1.5 & we must focus on instead on technological fixes to address overshoot - here’s why I think these arguments are distractions
