The British government played an important role when the world met in Paris last year to reach the ambitious agreement on reducing global CO2 emissions. Less than a year later, the pioneering agreement came into force and was ratified by the United Kingdom as a sign of a constant commitment to climate action around the world. The Paris agreement is not without its critics and it is not the agreement that everyone wanted. Many believe that emissions targets are not sufficient and stricter targets are needed to limit the effects of climate change. It is also worrying that some of the agreement`s commitments are not legally binding and, more recently, the President-elect of the United States has raised concerns by promising to withdraw the United States (responsible for 17.8% of global emissions) from the agreement. 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.  On June 1, 2017, U.S.
President Donald Trump announced that the United States would withdraw from the agreement.  Under Article 28, the effective withdrawal date of the United States is the fastest possible date, given that the agreement entered into force in the United States on November 4, 2016. If it had decided to withdraw from the UNFCCC, it could be informed immediately (the UNFCCC came into force in 1994 for the United States) and come into force a year later. On August 4, 2017, the Trump administration officially announced to the United Nations that the United States intends to withdraw from the Paris Agreement as soon as it has a legal right to do so.  The formal declaration of resignation could only be submitted after three years of implementation of the agreement for the United States in 2019.   We look at what this means and why this historic agreement is so important.
