In my eyes your proposal would have been resonable. Twenty or thirty years ago. I am just afraid that we are now past a line where any effective response would work without personal sacrifices. Of course it is still better to regulate manufacturers and companies to do the right things (or not do the wrong things). But we are now at a spot where we won't only have to think about CO2, we will also have to think about mitigating the consequences of the warming. And that means for example that food which uses 100 times more water per calorie than reasonable alternatives might not be something we can sustain anymore. That might mean we might have to make personal mobility more efficient, etc. And because we are doing it so late we have to do it on all fronts, because let's face it: what you propose will take too long even if we are doing it a magnitude faster than today.
