The contracting parties may, after three years of the agreement`s entry into force, withdraw from the agreement; However, they cannot express reservations about the agreement. It is rare that there is a 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. In addition, a clear framework has been put in place for all countries to make commitments to reduce emissions and strengthen these measures over time. Here are some important reasons why the agreement is so important: the NDCs are transformed into NDCs – nationally determined contributions – as soon as a country formally accedes 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. Taking part in an election campaign promise, Trump – a climate denier who has claimed that climate change is a “hoax” perpetrated by China, announced in June 2017 his intention to withdraw the United States from the Paris Agreement.
But despite the rose garden president`s statement that “we`re going out,” it`s not that simple. The withdrawal procedure requires that the agreement be in effect for three years before a country can formally announce its intention to withdraw. She`ll have to wait a year before she leaves the pact. This means that the United States could formally withdraw on November 4, 2020, the day after the presidential elections. Even a formal withdrawal would not necessarily be permanent, experts say. a future president could join us in a month. In the run-up to the Paris meeting, the United Nations has instructed countries to present plans detailing how they intend to reduce greenhouse gas emissions. These plans have been technically referred to as planned national contributions (INDC). As of December 10, 2015, 185 countries had introduced measures to limit or reduce their greenhouse gas emissions by 2025 or 2030.
In 2014, the United States announced its intention to reduce its emissions by 26-28% from 2005 levels by 2025. To achieve this goal, the country`s Clean Power Plan should set limits for existing and projected emissions from power plants. China, the country that emits the most greenhouse gases as a whole, has set a goal of reaching its carbon dioxide emissions “around 2030 and making the best efforts to reach an early peak.” The Chinese authorities have also sought to reduce carbon dioxide emissions per unit of gross domestic product (GDP) by 60-65% compared to 2005. 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.  The initial commitment period of the Kyoto Protocol was extended until 2012.
