Like all externalities, the solution isn't social shaming, it's taxation. We need to introduce a carbon tax, and tariffs on trade with countries that don't enforce an equivalent tax. I suggest this tax income be distributed equally among all citizens, so that it functions as compensation paid from those who emit more than their fair share to those who emit less. I see no problem with billionaires emitting enormous quantities of CO2 so long as they pay for it. Wealth needs to have some privileges for capitalism to function correctly, and capitalism (with the state doing its duty to regulate market failures) is the best economic system we have.
