Flying is just too cheap for the environment. 1 EUR per km for car/plain and 0.4-0.5 by train should be the minimum.
Besides, much more energy is wasted heating old, leaky homes that are an eauivalent of a wet dump. Landlords have no incentive to fix them because the tenants are the ones that pay for heating. If we fixed crappy housing im UK, allegendly worst in europe if yoy consider price, we would save a lot more CO2 and a lot more people would be happy.
Back to work, peasants!
Once you tax it markets will immediately respond by finding efficient, low carbon footprint alternatives to everything. That is, if people can get into their heads that capitalism is a system (to be tweaked for the benefit of everyone), not a religion.
By the way rich people will be the least affected global warming.
