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. The implementation of the agreement by all member countries will be evaluated every 5 years, the first evaluation will take place in 2023. The result will serve as a contribution to new Nationally Determined Contributions by Member States.  The assessment is not a contribution/achievement of individual countries, but a collective analysis of what has been achieved and what still needs to be done. The Paris Agreement is a historic environmental agreement adopted by almost all countries in 2015 to combat climate change and its negative impacts.
The agreement aims to significantly reduce global greenhouse gas emissions in order to limit the increase in global temperature this century to 2 degrees Celsius above pre-industrial levels, while looking for ways to limit the increase to 1.5 degrees. The agreement contains commitments from all major emitting countries to reduce their pollution from climate change and to strengthen these commitments over time. The Compact provides an opportunity for developed countries to support developing countries in their efforts to mitigate and adapt to climate change, and provides a framework for transparent monitoring, reporting and strengthening of individual and collective climate objectives of countries. On August 4, 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.   Am 4. In November 2019, the U.S. government filed the notification of resignation with the United Nations Secretary-General, the depositary of the agreement, and formally withdrew from the Paris Climate Agreement a year later, when the withdrawal entered into force.  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.   Both the EU and its Member States are individually responsible for ratifying the Paris Agreement.
A strong preference has been expressed for the EU and its 28 Member States to simultaneously deposit their instruments of ratification to ensure that neither the EU nor its Member States commit to fulfilling obligations that belong exclusively to each other, and fears of disagreements over each Member State`s share of the EU-wide reduction target – as well as the UK`s vote to leave the EU-wide the EU could delay the Paris Pact.  However, the European Parliament approved the ratification of the Paris Agreement on 4 October 2016, and the EU deposited its instruments of ratification on 5 October 2016 with several EU Member States.  The Parties recognise the importance of international support and cooperation in adaptation efforts and the importance of addressing the needs of developing country Parties, in particular those most vulnerable to the adverse effects of climate change. 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.  From November 30 to December 11, 2015, the France hosted representatives from 196 countries at the United Nations Climate Change Conference, one of the largest and most ambitious global climate conferences ever held.
The goal was nothing less than a binding, universal agreement that would limit greenhouse gas emissions to levels that would prevent global temperatures from rising more than 2°C (3.6°F) above the temperature scale set before the start of the Industrial Revolution. Yes, there is a broad consensus in the scientific community, although some deny that climate change is a problem, including politicians in the United States. When negotiating teams come together for international climate negotiations, there is “less skepticism about science and more disagreement about how to set priorities,” says David Victor, a professor of international relations at the University of California, San Diego. The basic science is as follows: This CFR backgrounder compares the actions countries are taking to combat climate change. The Parties recognize that adaptation is a global challenge facing all those with a local, subnational, national, regional and international dimension and that it is a key element of the long-term global response to climate change in order to protect people, livelihoods and ecosystems, taking into account the urgent and immediate needs of developing country Parties; who are particularly vulnerable to the adverse effects of climate change. .
