We need a personal carbon profile. E.g. this means that when you buy meat, etc. it is added to your personal carbon balance. Of course, it will require a complete overhaul of payment systems, but eventually this can lead to more awareness and hence a reduction of emissions.

A carbon tax at source (presumably, at a wholesale level) for electricity, natural gas, diesel, petrol etc would capture most of that, with a lot less effort.

That would certainly help, but paying != solving, unfortunately, unless you charge for storing CO2, which is rather expensive.
