According to the Office of the United States Trade Representative, the TPP contains “the most robust environmental commitments in history.  The USTR notes that the TPP requires signatories to comply with its obligations under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in order to protect and preserve iconic species.  According to the USTR, the TPP is the first trade agreement banning fishing-harmful subsidies such as those that contribute to overfishing.  The USTR states that TPP signatories are required to “fight illegal fishing,” “promote sustainable fisheries management practices,” “protect wetlands and important natural areas,” “fight illegal wildlife trade, illegal logging and illegal fishing” and “protect the marine environment from pollution from ships , including meeting its obligations under MARPOL (an international agreement for the prevention of marine pollution).”  In May 2015, U.S. Congressman Sander Levin argued that it was difficult to impose trade agreements because he questioned Vietnam`s willingness to comply with TPP labor standards.  According to a report by U.S. Senator Elizabeth Warren, there is a significant gap between the labour standards of previous U.S. free trade agreements and the effective application of those rules.  However, PIIE analysts note that studies show that the presence of “sticks” (possible suspension of trade benefits) and “carrots” (technical assistance) in trade agreements increases the likelihood that work commitments in trade agreements will have a positive effect; there are sticks as well as carrots in the TPP.  Opposition to the TPP agreement revolves around a number of issues. The secrecy of the negotiations is considered undemocratic.
Moreover, these opponents add that trade agreements are believed to be the source of foreign competition that contributes to the loss of production jobs in the United States. In addition, some opponents are concerned about the “Investor-State Dispute Settlement Clause” (ISDR), which allows companies to sue national governments that violate trade agreements. PolitiFact considers President Obama`s assertion that the Trans-Pacific Partnership “has a country like Malaysia that is really making serious efforts to combat human trafficking.”  PolitiFact notes that in June 2015, Malaysia began complying with the TPP and amending its legislation to improve the treatment of victims of human trafficking.  Among the amendments, Malaysia has granted victims better access to public shelter, transitional housing and more victim-friendly restitution procedures.  Malaysia has also taken steps to end human trafficking in the construction industry.  The White House cited statements of support from the World Wildlife Fund, the Nature Conservancy, the Humane Society, the Wildlife Conservation Society, Defenders of Wildlife, the International Fund for Animals, Global Animal Protection and other environmental groups for the TPP.   The Peterson Institute for International Economics argues that the TPP is “the most environmentally friendly trade agreement ever negotiated.”  With respect to ISDS, IPIE analysts note that there is little evidence of environmental policy restrictions arising from ISDS disputes.  Proponents of the agreement argue that trade agreements open up new markets for domestic industry.
