Many countries have indicated in their INDCs that they intend to use some form of international emissions trading to implement their contributions. To ensure the environmental integrity of these transactions, the agreement requires the parties to follow accounting practices that avoid double counting of “internationally transferred mitigation results.” In addition, the agreement introduces a new mechanism that contributes to containment and support for sustainable development and could generate or certify tradable emission units, depending on its design. Carbon dioxide, nitrous oxide and methane are gases that accumulate in the atmosphere and prevent heat from radiating from the Earth`s surface into space, creating the so-called greenhouse effect. According to the Intergovernmental Panel on Climate Change (IPCC), the leading international scientific body working on the issue, the concentration of these heat storage gases has increased dramatically since pre-industrial times to levels not seen in at least 800,000 years. Carbon dioxide (the main cause of climate change) has increased by 40%, nitrous oxide by 20% and methane by 150% since 1750 – mainly from the combustion of dirty fossil fuels. The IPCC says it is “extremely likely” that these emissions are mainly responsible for the rise in global temperatures since the 1950s. At the same time, deforestation and forest degradation have also contributed to their fair share of global carbon emissions. Currently, 197 countries – every nation on earth, the last signatory being war-torn Syria – have adopted the Paris Agreement. Of these, 179 have solidified their climate proposals with formal approval – including the US for now. The only major emitting countries that have not yet officially joined the deal are Russia, Turkey and Iran. The agreement recognises the role of non-party actors in the fight against climate change, including cities, other sub-national authorities, civil society, the private sector and others.
As the Paris Agreement is expected to apply after 2020, the first formal review under the agreement will not take place until 2023. But as part of a decision that accompanied the agreement, the parties decided to launch the five-year cycle with a “dialogue facilitating” collective progress in 2018 and the submission of NDCs by 2020 to 2030. The Paris Agreement reaffirms the commitments made by developed countries under the UNFCCC; The COP decision accompanying the agreement extends the target of $100 billion per year until 2025 and calls for a new target that starts from “a low of” $100 billion per year. The agreement also broadens the donor base beyond developed countries by encouraging other countries to provide “voluntary” support. China, for example, pledged $3 billion in 2015 to help other developing countries. The Paris Agreement is the first universal and legally binding global climate agreement adopted at the Paris Climate Change Conference (COP21) in December 2015. The agreement contains commitments from all countries to reduce their emissions and work together to adapt to the effects of climate change and calls on countries to strengthen their commitments over time. The agreement provides an opportunity for developed countries to assist developing countries in their mitigation and adaptation efforts, while providing a framework for transparent monitoring and reporting on countries` climate goals. Negotiators of the agreement said the INDCs presented at the Paris conference were inadequate and noted “with concern that the estimated overall greenhouse gas emissions in 2025 and 2030 resulting from the Intended Nationally Determined Contributions do not fall under the most cost-effective 2°C scenarios, but lead to a projected level of 55 gigatons in 2030.” and recognizing “that much greater efforts to reduce emissions will be needed to keep the increase in global average temperature below 2°C by reducing emissions to 40 gigatons or 1.5°C”.  [Clarification needed] Since Trump`s announcement, US envoys have continued to participate in UN climate negotiations as required to consolidate the details of the agreement.
Meanwhile, thousands of leaders across the country have stepped in to fill the void created by the lack of federal climate leadership, reflecting the will of the vast majority of Americans who support the Paris Agreement. Among city and state leaders, business leaders, universities, and individuals, there has been a wave of participation in initiatives such as America`s Pledge, the U.S. Climate Alliance, We Are Still In, and the American Cities Climate Challenge. Complementary and sometimes overlapping movements aim to deepen and accelerate efforts to combat climate change at local, regional and national levels. Each of these efforts is focused on the U.S. working toward the goals of the Paris Agreement, despite Trump`s attempts to steer the country in the opposite direction. The 32-page document provides a framework for global climate action, including climate change mitigation and adaptation, support to developing countries, as well as transparent reporting and strengthening of climate goals. Here`s what it`s supposed to do: Sign up for a weekly climate change chat on Facebook Messenger This will also allow the parties to gradually improve their contributions to the fight against climate change to achieve the long-term goals of the agreement. The Paris Agreement has a “bottom-up” structure unlike most international environmental treaties, which are “top-down” and are characterized by internationally defined norms and goals that must be implemented by states.  Unlike its predecessor, the Kyoto Protocol, which sets commitment targets with the force of law, the Paris Agreement, which emphasizes consensus-building, allows for voluntary, nationally defined targets.  Specific climate goals are therefore promoted politically and are not legally linked. Only the processes that govern the preparation of reports and the consideration of these objectives are prescribed by international law.
This structure is particularly noteworthy for the United States – since there are no legal mitigation or funding objectives, the agreement is considered an “executive agreement rather than a treaty.” Since the 1992 UNFCCC treaty received Senate approval, this new agreement does not need new congressional legislation to enter into force.  There is a lot of misinformation about the Paris Agreement, including the idea that it will hurt the U.S. economy. It was a series of unsubstantiated claims that Trump repeated in his 2017 speech in the rose garden, claiming that the deal would cost the U.S. economy $3 trillion by 2040 and $2.7 million in jobs by 2025, making us less competitive with China and India. But as fact-checkers noted, these statistics come from a debunked March 2017 study that exaggerated the future costs of emission reductions, underestimated advances in energy efficiency and clean energy technologies, and completely ignored the huge health and economic costs of climate change itself. Adaptation – measures to combat the effects of climate change – will be much more important under the Paris Agreement than before under the UNFCCC. Just as the Parties will submit mitigation contributions, the Agreement requires all Parties to plan and implement adaptation efforts “where necessary” and encourages all Parties to report on their adaptation efforts and/or needs. The agreement also provides for a review of progress on adaptation and the adequacy and effectiveness of adaptation support as part of the global stocktaking, to be carried out every five years. Developed countries have committed themselves under the UNFCCC to support mitigation and adaptation efforts in developing countries. Under the Copenhagen and Cancún Accords, developed countries committed to mobilize $100 billion a year in public and private financing for developing countries by 2020.
The level of NDCs set by each country will set that country`s objectives. However, the “contributions” themselves are not binding under international law because they do not have the specificity, normative character [clarification required] or mandatory language required to create binding norms.  In addition, there will be no mechanism that requires a country to set a target in its NDC by a certain date, and no application if a set target is not achieved in an NDC.   There will only be a “Name and Shame” system, or as János Pásztor, UN Under-Secretary-General for Climate Change, told CBS News (USA), a “Name and Encourage” plan.  Given that the agreement does not foresee any consequences if countries do not comply with their obligations, such a consensus is fragile. A net of nations withdrawing from the deal could trigger the withdrawal of more governments and lead to a total collapse of the deal.  The initial commitment period of the Kyoto Protocol has been extended until 2012. This year, delegates at COP18 in Doha, Qatar, agreed to extend the agreement until 2020 (excluding some developed countries that had withdrawn). They also reaffirmed their 2011 commitment at COP17 in Durban, South Africa, to create a new comprehensive climate agreement by 2015 that would commit all major emitters not covered by the Kyoto Protocol – such as China, India and the United States – to reduce their greenhouse gas emissions. The new treaty – the future Paris Agreement – is expected to completely replace the Kyoto Protocol by 2020. However, the Paris Agreement entered into force earlier than planned, in November 2016.
India`s INDC highlighted the challenges of eradicating poverty while reducing greenhouse gas emissions. About 24% of the world`s population without access to electricity (304 million) lived in India. .
