The EU`s first Nationally Determined Contribution (NDC) under the Paris Agreement was the commitment to reduce greenhouse gas emissions by at least 40% by 2030 compared to 1990 within the broader climate and energy framework by 2030. All key EU legislation to achieve this goal has been adopted by the end of 2018. The choice of the pre-industrial reference period as well as the method of calculating the global average temperature may change scientists` estimates of historical warming by a few tenths of a degree Celsius. Such differences become important in the context of a global temperature limit that is only half a degree above what we are now. But assuming consistent definitions are used, they have no bearing on our understanding of how human activities affect climate. A new issue that emerged at the centre of the Paris negotiations arose from the fact that many of the worst impacts of climate change will be too severe or too rapid to be avoided by adaptation measures. The Paris Agreement explicitly recognizes the need to address such loss and damage and aims to find appropriate responses.  It clarifies that loss and damage can take various forms, both as immediate effects of extreme weather events and as slow effects, such as. B, land loss due to sea level rise for low-lying islands.  The agreement requires rich countries to meet a funding commitment of $100 billion per year beyond 2020 and use this figure as a «lower limit» for additional support agreed until 2025.
The Kyoto Protocol, a landmark environmental treaty adopted at COP3 in Japan in 1997, is the first time that countries have agreed on country-specific emission reduction targets that are legally mandated. The protocol, which only entered into force in 2005, set binding emission reduction targets only for developed countries, based on the assumption that they were responsible for most of the Earth`s high greenhouse gas emissions. The United States first signed the agreement, but never ratified it; President George W. Bush argued that the deal would hurt the U.S. economy because it would not include developing countries such as China and India. Without the participation of these three countries, the effectiveness of the treaty proved limited, as its objectives covered only a small fraction of total global emissions. However, it is important to remember that the Paris Agreement is not static. Instead, it is designed to amplify countries` national efforts over time – meaning that current commitments are the ground, not the ceiling of climate change ambitions. Much remains to be done – reducing emissions by 2030 and 2050 – and the agreement provides the tools to achieve this. When the agreement reached enough signatures on October 5, 2016 to cross the threshold, US President Barack Obama said, «Even if we achieve all the goals.» We will only reach part of where we need to go. He also said that «this agreement will help delay or avoid some of the worst consequences of climate change.
It will help other countries reduce their emissions over time and set bolder targets as technology advances, all within a robust transparency system that allows each country to assess the progress of all other nations.   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. The NRDC is working to make the Global Climate Action Summit a success by encouraging more ambitious commitments to the historic 2015 agreement and initiatives to reduce pollution. To avoid major changes in life as we know it, global measures must be taken. Hence the Paris Agreement, which sets the ultimate goal of limiting the rise of global warming to 1.5 degrees Celsius this century. In fact, the seemingly small difference between 1.5 and 2 degrees could have a dramatic impact on low-lying nations and coral reefs. It is rare that there is consensus among almost all nations on a single issue. But with the Paris Agreement, world leaders agreed that climate change is driven by human behavior, that it poses a threat to the environment and all of humanity, and that global action is needed to stop it. A clear framework has also been put in place for all countries to make commitments to reduce emissions and strengthen these measures over time.
Here are some key reasons why the agreement is so important: National communication reports are often several hundred pages long, covering a country`s actions to reduce greenhouse gas emissions, as well as a description of its vulnerabilities and the impacts of climate change.  National communications are prepared in accordance with guidelines agreed by the Conference of the Parties to the UNFCCC. The Nationally Determined Contributions (NDCs) that form the basis of the Paris Agreement are shorter and less detailed, but also follow a standardized structure and are subject to technical review by experts. 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. Recognizing that many developing countries and small island states that have contributed the least to climate change could suffer the most from its consequences, the Paris Agreement includes a plan for developed countries – and others that are «able to do so» – to continue to provide funds to help developing countries mitigate and increase their resilience to climate change. The agreement builds on financial commitments from the 2009 Copenhagen Accord, which aimed to increase public and private climate finance for developing countries to $100 billion a year by 2020.
(To put this in perspective, global military spending in 2017 alone amounted to about $1.7 trillion, more than a third of which came from the United States.) The Copenhagen Compact also created the Green Climate Fund to help mobilize transformative financing with targeted public funds. The Paris Agreement set hope that the world would set a higher annual target by 2025 to build on the $100 billion target for 2020 and put in place mechanisms to achieve that scale. While increasing NDC ambitions is an important objective of the global inventory, it assesses efforts that go beyond mitigation. The 5-year reviews will also assess adaptation, climate finance regulations, and technology development and transfer.  In principle, the term «pre-industrial level» could refer to any period prior to the beginning of the Industrial Revolution. But the number of direct temperature measurements decreases as we go back in time. The definition of a «pre-industrial» reference period is therefore a compromise between the reliability of temperature information and its representativeness for truly pre-industrial conditions. Some pre-industrial periods are cooler than others for purely natural reasons.
This could be due to spontaneous climate fluctuations or climate response to natural disturbances such as volcanic eruptions and fluctuations in solar activity. This IPCC special report on global warming of 1.5°C uses the reference period 1850-1900 to represent pre-industrial temperature. This is the first period with near-global observations and the reference period used as an approximation of pre-industrial temperatures in the IPCC`s Fifth Assessment Report. The Paris Agreement was opened for signature on 22 April 2016 (Earth Day) at a ceremony in New York.  After several European Union states ratified the agreement in October 2016, enough countries that had ratified the agreement were producing enough greenhouse gases worldwide for the agreement to enter into force.  The agreement entered into force on November 4, 2016.  The 4. In August 2017, the Trump administration sent an official notice to the United Nations stating that the United States intended to withdraw from the Paris Agreement as soon as it was legally allowed to do so.  The formal declaration of withdrawal could only be submitted when the agreement for the United States was in force for 3 years on November 4, 2019.   On November 4, 2019, the U.S.
government filed the notification of resignation with the Secretary-General of the United Nations, depositary of the agreement, and formally withdrew from the Paris Climate Agreement a year later, when the withdrawal took effect.  After the November 2020 election, President-elect Joe Biden promised to reinstate the United States in the Paris Agreement on his first day in power and to renew America`s commitment to mitigating climate change.   The Paris Agreement marks the beginning of a transition to a low-carbon world – much more needs to be done.
