Surely you are not suggesting that we in the US and other industrialized countries with large economic middle classes ought to be responsible for what Asian, India, and South American countries do? Who has the duty to pay for pollution control technoligies? I submit that it is the responsibility of those countries to do so, not the taxpayers of the developed countries.
I also submit the hodgepodge of local gasoline formulation requirements is also helping to drive the price of gasoline and diesel up. Why can't we have a single formulation for each octane level of gasoline for summer and a single one for winter instead of the 60 or so for summer and the additonal 60 or so for winter we have now in the US?
