Earlier in the week a handful of senior  Democratic Senators announced that they would be changing a provision  in a bill recently passed by the House of Representatives that imposes  carbon taxes on imports. According to FT.com, the original bill contained “tough provisions  to impose carbon tariffs, aimed at protecting American companies’  competitiveness against imports from countries without equivalent carbon  emission controls.” Both leaders in the Senate, and the Obama administration  have warned that such a provision could spark a global trade war, and  Chinese officials have already spoken out about it. 
 
Senator John Kerry, who is helping to  write the senate’s version of the bill, said in a hearing on the issue  on Wednesday: “We have already come to the conclusion in working on  the Senate bill that we’re going to try and change that provision  . . . we haven’t landed yet completely on where we come out”.
 
Max Baucus, the Democrat senator who  chairs the senate finance committee, said any provisions that “provoke  retaliation from our trading partners will only hurt the same industries  we’re trying to help”, adding that he was “confident we can craft  legislation that strikes the right balance”.
Differences in the two versions of the  bill will eventually have to be reconciled before passing into law.
 
President Barack Obama has warned the  House’s carbon tariffs plan could send the wrong signal to trading  partners. India called the measures “pernicious” while China said  they would violate World Trade Organization principles and amounted  to “trade protectionism in the disguise of environmental protection”.
 
A recent report from the WTO said that  such “border tax adjustments” could in theory be made consistent  with WTO rules, but trade lawyers stress that crafting such laws is  likely to be very difficult in practice.
