Several tech executives – including Google CEO Sundar Pichai, Microsoft president and legal director Brad Smith, Apple CEO Tim Cook, Facebook CEO Mark Zuckerberg and General Electric CEO Jeff Immelt – condemned the decision.   Microsoft`s Satya Nadella stated that Microsoft believes that „climate change is an urgent issue that requires global action.” Google`s Sundar Pichai tweeted: „Disappointed with today`s decision. Google will continue to work hard for a cleaner and more prosperous future for all. Facebook`s Mark Zuckerberg said: „The exit from the Paris climate agreement is bad for the environment, bad for the economy and threatening the future of our children. Although the United States and Turkey are not parties to the agreement, as they have not indicated their intention to withdraw from the 1992 UNFCCC, they will continue to be required, as an „Annex 1” country under the UNFCCC, to end national communications and establish an annual inventory of greenhouse gases.  The Paris Agreement was launched at the signing on April 22, 2016 (Earth Day) at a ceremony in New York.  After the agreement was ratified by several EU member states in October 2016, there were enough countries that had ratified the agreement to produce enough greenhouse gases in the world for the agreement to enter into force.  The agreement came into force on November 4, 2016.  The EU and its member states are individually responsible for ratifying the Paris Agreement. There was a strong preference for the EU and its 28 Member States to simultaneously table their ratification instruments to ensure that neither the EU nor its Member States commit to commitments that belong exclusively to the other and there was concern that there was a disagreement on each Member State`s share of the EU-wide reduction target.
just as Britain`s vote to leave the EU could delay the Paris pact.  However, on 4 October 2016, the European Parliament approved the ratification of the Paris Agreement and the EU tabled its ratification instruments on 5 October 2016 with several EU Member States.  The level of NCC set by each country will determine the country`s objectives. However, the „contributions” themselves are not binding under international law because of the lack of specificity, normative nature or language necessary to establish binding standards.  In addition, there will be no mechanism to compel a country to set a target in its NDC on a specified date and not for an application if a defined target is not achieved in an NDC.   There will be only a „Name and Shame” system  or as UN Deputy Secretary General for Climate Change, J. Pésztor, CBS News (US), a „Name and Encouragement” plan.  Since the agreement has no consequences if countries do not live up to their commitments, such a consensus is fragile.
