The energy bill recently passed in the House puts limits on CO2 emitted in the US with a goal of reducing our CO2 output by 85% by 2050, but makes no effort whatsoever to address the CO2 output (or other pollution) from goods produced outside of the US.
Good thing the US doesn't share an atmosphere with any other countries.
Or a jobs market. (Making energy expensive in the US will push energy-intensive production overseas, taking factory jobs with it.)
How hard would it be to include an imported goods section? Something like:
All imported goods from countries that do not have equivalent CO2 capping programs must pay a CO2 tax equal to what a domestic competitor would pay.
Personally, I care a lot more about the arsenic and sulfur clouds floating over from China, but forcing them to participate in a CO2 program or come up with their own would be a good first step.
