Happy to oblige.
Aridas (like dann a few pages back) does have a point about self-interested bad actors on the "supply" side interfering with concerted action. The problem is, from ground level, stopping them from doing that is just as intractable a problem as reducing demand in the face of that interference. Achieving either aim is doubtful unless someone with that agenda acquires dictatorial power.
The bad-actor industries and bad-actor politicians and the complacent public, the supply side and the demand side, aren't opponents of one another, they're an axis of common interest. This includes the majority of the developed world and most climate activists. Do hordes of oligarchs showing up in private jets and yachts for global climate conferences seem incongruous? They're actually not.
Who are their opponents? For all practical purposes, no one. The poor who consume and pollute less by necessity have no leverage on the supply or demand sides. A tiny contingent of fringe climate passivists practices austerity primarily to escape a status quo they see as increasingly demanding, unhealthy, and/or fragile, not to try to rescue it (or the planet).
