An article in Aljazeera America (January 21, 2016) titled “TPP would facilitate lawsuits against governments, critics say” (http://america.aljazeera.com/articles/2016/1/21/tpp-would-erode-environmental-protections.html) explains that the TPP erode American sovereignty and threaten progress on climate change. The environmental group Sierra Club agrees that the TPP would expand the number of corporations able to sue governments for what they consider as unfair restraints on trade. Under the TPP, approximately 9,000 companies doing business in the US would receive expanded foreign rights to sue over lost profits. The costs implied in these legal actions may prevent the government to enact environmental policies that could harm foreign investors. In this way, critics mention that the TPP will make foreign companies in control of some important aspects of the American sovereignty. How risky could it be for the American Sovereignty that the TPP deal is approved?
