Many people believe that climate change can't be "solved" in a vacuum and has to be approached with broad measures to be palatable or even "solvable".
I haven't checked for America, but at least in Germany it's pretty obvious that with the expected transition to electrical vehicles, it will not happen fast enough to reach the climate goals. But at the same time, electric vehicles have significant pollution in the manufacturing stage, so just making them a lot cheaper might not be a solution (and lead to more demand for vehicles, since they're suddenly much cheaper, leading to unintended emission). Additionally vehicles are getting larger (increasing energy usage) and more miles get driven. This means car mobility has to be reduced or at least kept at the same level.
This is certainly not an easy problem and probably has to be associated with vast changes across society, like rezoning, changing work & mobility. And that's just a single example.
It's also pretty obvious (IMHO) that SAF won't available in a large-enough scale to make much of a difference to flying emissions in the next decades. But flights are booming around the world (with a small damper due to covid) and could make up as much as 10% of global warming contribution in 15 years which (IMHO) looking at the benefits is way too much. What do you do there?
Housing is difficult (how do you incentivize moving to efficient heating based on electricity without people dying because they need to save on heating), adoption to climate change is difficult (sorry, you can't live/build new houses here anymore), ... .
How do you avoid that pricing emissions hurts poor people the most and thus discourages/punishes politicians?
These are all topics with no simple answers and possibly unpopular solutions with no great alternatives. But "solving" climate change is a very multidisciplinary problem, with many unpopular issues associated with it.
It's very easy to tie something to climate change, even if it might not make much sense when looking at it in greater detail. But it's also very easy to surface level say "What's that to do with climate change?" even though for almost any measure you can argue for at-least some benefit.
