The core reason there is no plan is that it's not practicable to make enough impact on climate change with any realistic approach to generate a different that we can measure. This is OBVIOUS and well documented. Whatever we spend, whatever we DO, is not going to matter longer term in any measurable sense.
That is why no one talks about this, or wants to discuss it. They focus on the sky is falling we have to DO something and don't want to confront the FACT that the horse is out of the barn. We could spend huge amounts and the impact would be tiny, not measurable.
We need a realistic approach that deals with the actual problem.
