From 30 November to 11 December 2015, France hosted representatives from 196 countries at the end of the Un Climate Change Conference (UN), one of the largest and most ambitious global meetings ever held. The goal was nothing less than a binding and universal agreement to limit greenhouse gas emissions to levels that would prevent global temperatures from rising more than 2oC above the lower temperature levels set before the start of the industrial revolution. President Trump is pulling us out of the Paris climate agreement. InDCs become CNDs – nationally determined contributions – as soon as a country formally adheres to the agreement. There are no specific requirements as to how or how many countries should reduce emissions, but there were political expectations about the nature and rigour of the targets set by different countries. As a result, the scale and ambition of national plans vary widely, largely reflecting each country`s capacity, level of development and contribution to emissions over time. China, for example, has committed to cleaning up its CO2 emissions by 2030 at the latest and reducing CO2 emissions per unit of gross domestic product (GDP) by 60-65% by 2030 from 2005 levels. India has set a target of reducing emissions intensity by 33-35% from 2005 levels by 2030 and producing 40% of its electricity from non-fossil fuels. The agreement entered into force on 4 November 2016, 30 days after the ratification on 5 October 2016 of at least 55 countries representing at least 55% of global emissions. 6. The Paris climate agreement is not yet in force. What we need is action: the Paris Agreement has been ratified by 179 countries, including Australia, the United States, China, the EU, India and all the other major emitters.
US President Donald Trump has said the US wants to leave the agreement, but cannot legally resign formally by November 2020. Trump`s America is the only country in the world to say it will renounce its obligations to the international community. 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.  Of the 196 negotiating countries that have signed the agreement, 181 parties have ratified it to date. Recognizing that many developing countries and small island developing states that have contributed the least to climate change are most likely to suffer the consequences, the Paris Agreement contains a plan for developed countries – and others that are able to do so – to continue to provide financial resources to help developing countries reduce and increase their capacity to withstand climate change. The agreement builds on the financial commitments of the 2009 Copenhagen Accord, which aimed to increase public and private climate finance to developing countries to $100 billion per year by 2020.
