While climate crisis is a global issue, almost all the power for taking major, large-scale action resides at the national level. The international structure is (and is explicitly designed to be) nearly incapable of forcing major nations to do anything without their consent, so global agreements and major multilateral action (e.g. affecting the global oil supply) are feasible if and only if they are aligned with what's acceptable and desired by the separate nations.
In that regard, if we're looking at how to motivate change to actually happen, it is appropriate to look at the incentives that would/wouldn't make sense from the national perspective - because otherwise it's just empty PR and wishful thinking, proposals that have no chance to get implemented. And, to put it explicitly, climate change is not currently overriding most other aspects of national interests, far from it, it's not (yet?) the #1 or even #3 concern in most countries elections or unelected leader motivations.
