Negotiators of the agreement said that the INDCs presented at the time of the Paris conference were not sufficient. concerned that aggregate greenhouse gas emission estimates for 2025 and 2030, resulting from projected national contributions, are not covered by the most cost-effective scenarios at 2oC, but result in a forecast level of 55 gigatonnes. By 2030, and acknowledging “that much greater efforts will be needed to reduce emissions in order to keep the increase in the average global temperature to less than 2 degrees Celsius by reducing emissions to 40 gigatonnes or 1.5 degrees Celsius.   [Clarification needed] The White House said that Trump would end the implementation of the CO2 reduction targets set by former President Barack Obama and that the withdrawal would be in accordance with the years of withdrawal processes provided for by the agreement.  On September 16, 2017, an EU official said that the Trump administration had apparently weakened its position on exiting the agreement. The White House informed the press that it had not changed its position on the agreement.   How each country is on track to meet its obligations under the Paris Agreement can be tracked continuously online (via the Climate Action Tracker  and the climate clock). The EU and its member states are among the nearly 190 parties to the Paris Agreement. The EU formally ratified the agreement on 5 October 2016, allowing it to enter into force on 4 November 2016. In order for the agreement to enter into force, at least 55 countries representing at least 55% of global emissions had to file their ratification instruments.
While mitigation and adjustment require more climate funding, adjustment has generally received less support and has mobilized fewer private sector actions.  A 2014 OECD report showed that in 2014, only 16% of the world`s financial resources were devoted to adaptation to climate change.  The Paris Agreement called for a balance between climate finance between adaptation and mitigation, highlighting in particular the need to strengthen support for adaptation from the parties most affected by climate change, including least developed countries and small island developing states. The agreement also reminds the parties of the importance of public subsidies, as adjustment measures receive less public sector investment.  John Kerry, as Secretary of State, announced that the United States would double its grant-based adjustment funding by 2020.  The implementation of the agreement by all the Member States combined will be evaluated every five years, with the first evaluation in 2023. The result will be used as an input for new national contributions from Member States.  The inventory will not be national contributions/achievements, but a collective analysis of what has been achieved and what remains to be done.
