Ideally, we should try to reduce emissions as much as possible in every way possible, prioritizing those that don't reduce standards of living, but to the degree that we need to, say, drive less, we should do that too. I honestly think that most peoples lives would be better, not if they just drove less with all else being the same, but if our cities and towns were changed in such a way that we didn't NEED to drive nearly as much. The less driving we need to do, the easier it is to decarbonize it.
To be tongue-in-cheek: just tax carbon lol.
Not disagreeing with you, but everything by itself is a drop in the ocean compared with the total - the "coordinated effort to de-carbonize" starts with doing what's possible and reducing CO2 use of land travel is a lot easier than for the military, commercial shipping, and air travel at the moment.
Or animal agriculture.
