> Do these people even know the carbon footprint of manufacturing a solar panel or a wind mill for their "green" energy?

Yes, and it can't be ignored. A carbon tax is universal

I don't get your whining on the middle class. Everyone can strive for a climate friendly life style. This generates a demand on a big scale, thus also solutions.

A dividend would help people having not much money and still need to use carbon intensive products (until there are alternatives), because they have a small footprint anyways
