Actually, with america not able to directly control what a nation does, it is neither fair nor sophisticated. In fact, it is akin to telling a rape victim that s?he owes their rapist for services rendered.
Instead, we should put an increasing tax on all goods based on where the parts come from. In addition, the normalization should be co2 / $GDP. With this approach nations like India which actually has a low emission / $GDP will have a lower to none existent tax, while nations / states such as China, or wyoming , america, will have high tax unless they change their way.
