At the 2015 Paris conference, at which the agreement was negotiated, developed countries reaffirmed their commitment to mobilize $100 billion a year to finance climate by 2020 and agreed to continue mobilizing $100 billion a year by 2025.  The commitment refers to the existing plan to allocate $100 billion per year to developing countries for climate change adaptation and climate change mitigation.  InDCs become NDCs – 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 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 negotiators of the agreement stated that the INDCs presented at the time of the Paris conference were insufficient and found that “the estimates of aggregate greenhouse gas emissions in 2025 and 2030, resulting from planned contributions at the national level, do not fall into scenarios at 2oC at the lowest cost, but lead to a projected level of 55 gigatonnes in 2030.” and acknowledges that “much greater efforts to reduce emissions will be needed to keep the global average temperature rise to less than 2 degrees Celsius, by reducing emissions to 40 gigatonnes or 1.5 degrees Celsius.”  [Clarifications needed] To contribute to the goals of the agreement, countries have presented comprehensive national plans to combat climate change (contributions determined at national level. NDC). These are not yet sufficient to meet the agreed temperature targets, but the agreement points to the way forward for further measures. The Paris Agreement is the world`s first comprehensive climate agreement.  It is rare that there is consensus among almost all nations on a single subject. But with the Paris agreement, world leaders agreed that climate change was driven by human behaviour, that it was a threat to the environment and to humanity as a whole, and that global action was needed to stop it.
