In 2016, Greenpeace published 248 pages of secret documents from TTIP`s trade negotiations.  Greenpeace Netherlands said it had published the documents “to ensure the necessary transparency and to stimulate an informed debate on the treaty.”  In March 2013, a coalition of digital rights organizations and other groups issued a statement calling on negotiators to “have TTIP debated in the US Congress, the European Parliament, national parliaments and other transparent for a,” instead of “conducting closed negotiations that give privileged access to insiders” and abandoning the intellectual property of the agreement. The texts of the TTIP agreement are drawn up by 24 joint working groups between the EU and the US, each taking into account a separate aspect of the agreement. Development usually takes a number of phases. First, large-scale position papers will be exchanged, introducing each party`s objectives and ambitions for each aspect. This is followed by proposals for texts from both parties, accompanied (in areas such as tariffs and market access) by the “initial offer” of each party. These negotiations and draft documents can evolve during the different phases of their development. If both parties are ready, a consolidated text will be prepared, with the remaining differences of discussion expressed between brackets. These texts are then closed thematically when a working consensus is reached. However, the agreement will be negotiated as a whole, so that no text of the subject will be finalized until a full consensus has been reached.
 In response to the criticism, the European Commission published negotiating documents months after its revelations by Greenpeace, including all EU proposals in the regulatory and regulatory elements of the agreement.    The Trade Commissioner described the negotiations as “the most transparent trade negotiations ever conducted by the EU”.  The Guardian called TTIP “the most controversial trade agreement ever negotiated by the EU.”  TTIP negotiations are criticised and rejected by some trade unions, charities, NGOs and environmentalists, particularly in Europe.   The Independent summarizes the negative effects of TTIP as “reducing regulatory barriers to large companies, food security, environmental legislation, banking regulation and sovereigns of different nations” or more critical than “the attack on European and American companies by transnational groups”.  German economist Max Otte stated that proposed arbitration (ISDR) and the protection of foreign investment would mean a “total deviation from policy” and that free trade agreements on the labour economy would generally apply lower standards and that the TTIP would put European workers in direct competition with the Americans (and, in fact, under the North American free trade agreement with the Mexicans). which would have an impact on European social models.  Otte also concluded: “We really don`t want the social system of these countries [U.S. and Mexico] here [in Europe].”  Trade policy is not only related to foreign affairs.
