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. The countries most affected by the effects of climate change will be low-lying nations, particularly vulnerable to sea level rise, and developing countries that do not have the resources to adapt to changes in temperature and precipitation. But prosperous nations like the United States are also increasingly vulnerable. In fact, millions of Americans – especially children, the elderly and the poor – are already suffering from the wrath of climate change. (b) improving the ability to adapt to the negative effects of climate change and promoting resilience to climate change and the development of low greenhouse gas emissions so as not to endanger food production; 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 the planned contributions at the national level are not covered by the least expensive scenarios of 2oC, but lead to a projected level of 55 gigatons 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.”  [Clarification needed] “The ue-Green Agreement and the commitments of China, Japan and South Korea on carbon neutrality indicate the inevitable of our collective transition from fossil fuels” said Laurence Tubiana, one of the architects of the Paris Agreement and now director general of the European Climate Foundation. 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.
