I believe the idea is to implement the plan as fully as possible as soon after the election as possible. The problem is that as of now THERE IS NO PROGRAM TO IMPLEMENT. A program limited only to climate, and no other aspect of any GND proposal, would have to include both the technical aspects of shedding the carbon addiction but also the political and economic aspects of that major reconstruction of the economy and society. I’m not thinking of the details that can only be worked out on the fly in real time, but just the outlines, such as what carbon sources are to be reduced by how much on what schedule, with a significant margin for error, the reason the serious climate hawks are calling for what almost certainly IS impossible, net zero carbon by 2030. Does Beto have any personal knowledge of how any of that works? I doubt it, the reason he latched onto the 2030 notion without getting a slightly broader familiarity with a problem that so far people much more knowledgeable than he are approaching with caution. IMNSHO it is still possible–barely–to get to zero carbon emissions by 2050, but the time is very short and the path is very narrow, getting more so every day.
