A carbon tax would be lucrative for helping fund a Global Government to deliver nice things to those poorer nations that the wealthy nations harmed by their excessive creation of carbon gases.
Pretty slick ....right!
Oddly enough, many of those poorer nations are at tropical latitudes where they don't require much heat to keep from freezing to death.
I guess when you build a fire and boil water, you start seeing other things that can be done with the fire... and steam...and develop technology just not necessary elsewhere.
Considering that poorer nations cook over open fires with no emissions control, on a per BTU basis, I would wager their energy consumption is far filthier than those regions which may consume a lot more energy, but tend to do so far more efficiently.
This would amount to penalizing those who are using their energy efficiently and with lower emissions per BTU in favor of those who are not doing that at all.
In short, the money will be taken from those doing it right and given to those who do not, on the assumption that those who do not are somehow harmed by those doing things right.
Nope, not happening, no see-gar.
