I guess I wasn't very clear.
The problem is that if an individual makes every single choice they can to reduce their CO2 footprint, they still won't make a dent in CO2 emissions. It's effectively pissing in the ocean.
So, you can connect it to status and make people feel good, but you have to go after the big things if you want to actually dent CO2 emissions (this is simply a case of Amdahl's law in reverse).
And the big one is transportation. If you can get every single car and truck onto electricity, you win multiple times. Traffic jams don't convert energy to CO2; electric motors are quite a bit more efficient than internal combustion engines at low speeds with high torque; multiple distributed CO2 sources now become single point sources (at the power plant--much easier to apply technology to).
After that, the next big thing, if I remember correctly, is that you need to switch from AC transmission lines to high-voltage DC transmission lines as the loss is so much better. And a LOT of energy gets lost to simple transmission (also has the advantage that your grids are much easier to interconnect and stabilize).
After those two, then you take a look around and see what the next big 2 or 3 are, and go attack those. Lather. Rinse. Repeat. Until you are at CO2 negative.
