The really bad part is that carbonbriefs analysis is that the Biden line is only the laws Biden has passed or is about to pass, before the election not being revoked by Trump. So if Biden actually gets elected he can and probably will do more, bringing the actual results much closer to the Target line. However being able to create a graph, seems to hard for a modern PR team.
Not from US, so pardon my lack of knowledge on this, but I read some comments that mentioned that it will require the Congress to sign off on it, and that's still largely republican?
There are a lot of procoporate enviromental policies. Building renewables, EVs, public transport and so forth is pumping money into the economy, which cooperations love. Obviously it is not enough and the US has to activly lower consumption to do enough to keep climate change manageable. For that you need activists. However corportists like Biden are activly working on making real things in America, which is a hell of a lot better then the finance presidents before that. To be fair Trump is also a corporatist, but he does nothing for the enviroment.
