The Paris Agreement (French: Accord de Paris), Paris climate accord or Paris climate agreement, is an agreement within the United Nations Framework Convention on Climate Change (UNFCCC) dealing with greenhouse gas emissions mitigation, adaptation and finance starting in the year 2020. The language of the agreement was negotiated by representatives of 196 parties at the 21st Conference of the Parties of the UNFCCC in Paris and adopted by consensus on 12 December 2015. As of August 2017, 195 UNFCCC members have signed the agreement, 160 of which have ratified it.
In the Paris Agreement, each country determines, plans and regularly reports its own contribution it should make in order to mitigate global warming. There is no mechanism to force a country to set a specific target by a specific date, but each target should go beyond previously set targets.
In 2017, U.S. President Donald Trump announced his intention to withdraw the United States from the agreement, causing widespread condemnation in the European Union and many sectors in the United States. Under the agreement, the earliest effective date of withdrawal for the U.S. is November 2020.
In July 2017, France’s environment minister Nicolas Hulot announced France’s five-year plan to ban all petrol and diesel vehicles by 2040 as part of the Paris Agreement. Hulot also stated that France would no longer use coal to produce electricity after 2022 and that up to €4bn will be invested in boosting energy efficiency.
The aim of the convention is described in Article 2, "enhancing the implementation" of the UNFCCC through:
The Paris deal is the world's first comprehensive climate agreement.
The contributions that each individual country should make in order to achieve the worldwide goal are determined by all countries individually and called "nationally determined contributions" (NDCs). Article 3 requires them to be "ambitious", "represent a progression over time" and set "with the view to achieving the purpose of this Agreement". The contributions should be reported every five years and are to be registered by the UNFCCC Secretariat. Each further ambition should be more ambitious than the previous one, known as the principle of 'progression'. Countries can cooperate and pool their nationally determined contributions. The Intended Nationally Determined Contributions pledged during the 2015 Climate Change Conference serve—unless provided otherwise—as the initial Nationally determined contribution.
The level of NDCs set by each country will set that country's targets. However the 'contributions' themselves are not binding as a matter of international law, as they lack the specificity, normative character, or obligatory language necessary to create binding norms. Furthermore, there will be no mechanism to force a country to set a target in their NDC by a specific date and no enforcement if a set target in an NDC is not met. There will be only a "name and shame" system or as János Pásztor, the U.N. assistant secretary-general on climate change, told CBS News (US), a "name and encourage" plan. As the agreement provides no consequences if countries do not meet their commitments, consensus of this kind is fragile. A trickle of nations exiting the agreement may trigger the withdrawal of more governments, bringing about a total collapse of the agreement.
The negotiators of the Agreement, however, stated that the NDCs and the 2 °C reduction target were insufficient; instead, a 1.5 °C target is required, noting "with concern that the estimated aggregate greenhouse gas emission levels in 2025 and 2030 resulting from the intended nationally determined contributions do not fall within least-cost 2 °C scenarios but rather lead to a projected level of 55 gigatonnes in 2030", and recognizing furthermore "that much greater emission reduction efforts will be required in order to hold the increase in the global average temperature to below 2 °C by reducing emissions to 40 gigatonnes or to 1.5 °C".
Although not the sustained temperatures over the long term which the Agreement addresses, in the first half of 2016 average temperatures were about 1.3 °C (2.3 degrees Fahrenheit) above the average in 1880, when global record-keeping began.
When the agreement achieved enough signatures to cross the threshold on 5 October 2016, US President Barack Obama claimed that "Even if we meet every target ... we will only get to 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 nations ratchet down their emissions over time, and set bolder targets as technology advances, all under a strong system of transparency that allows each nation to evaluate the progress of all other nations."
The global stocktake will kick off with a "facilitative dialogue" in 2018. At this convening, parties will evaluate how their NDCs stack up to the nearer-term goal of peaking global emissions and the long-term goal of achieving net zero emissions by the second half of this century.
The implementation of the agreement by all member countries together will be evaluated every 5 years, with the first evaluation in 2023. The outcome is to be used as input for new nationally determined contributions of member states. The stocktake will not be of contributions/achievements of individual countries but a collective analysis of what has been achieved and what more needs to be done.
The stocktake works as part of the Paris Agreement's effort to create a "ratcheting up" of ambition in emissions cuts. Because analysts have agreed that the current NDCs will not limit rising temperatures below 2 degrees Celsius, the global stocktake reconvenes parties to assess how their new NDCs must evolve so that they continually reflect a country's "highest possible ambition".
While ratcheting up the ambition of NDCs is a major aim of the global stocktake, it assesses efforts beyond mitigation. The 5 year reviews will also evaluate adaptation, climate finance provisions, and technology development and transfer.
The Paris Agreement has a 'bottom up' structure in contrast to most international environmental law treaties which are 'top down', characterised by standards and targets set internationally, for states to implement. Unlike its predecessor, the Kyoto Protocol, which sets commitment targets that have legal force, the Paris Agreement, with its emphasis on consensus-building, allows for voluntary and nationally determined targets. The specific climate goals are thus politically encouraged, rather than legally bound. Only the processes governing the reporting and review of these goals are mandated under international law. This structure is especially notable for the United States—because there are no legal mitigation or finance targets, the agreement is considered an "executive agreement rather than a treaty". Because the UNFCCC treaty of 1992 received the consent of the Senate, this new agreement does not require further legislation from Congress for it to take effect.
Another key difference between the Paris Agreement and the Kyoto Protocol is their scopes. While the Kyoto Protocol differentiated between Annex-1 and non-Annex-1 countries, this bifurcation is blurred in the Paris Agreement, as all parties will be required to submit emissions reductions plans. While the Paris Agreement still emphasizes the principle of "Common but Differentiated Responsibility and Respective Capabilities"—the acknowledgement that different nations have different capacities and duties to climate action—it does not provide a specific division between developed and developing nations.
Article 6 has been flagged as containing some of the key provisions of the Paris Agreement. Broadly, it outlines the cooperative approaches that parties can take in achieving their nationally determined carbon emissions reductions. In doing so, it helps establish the Paris Agreement as a framework for a global carbon market.
Paragraphs 6.2 and 6.3 establish a framework to govern the international transfer of mitigation outcomes (ITMOs). The Agreement recognizes the rights of Parties to use emissions reductions outside of their own jurisdiction toward their NDC, in a system of carbon accounting and trading.
This provision requires the "linkage" of various carbon emissions trading systems—because measured emissions reductions must avoid "double counting", transferred mitigation outcomes must be recorded as a gain of emission units for one party and a reduction of emission units for the other. Because the NDCs, and domestic carbon trading schemes, are heterogeneous, the ITMOs will provide a format for global linkage under the auspices of the UNFCCC. The provision thus also creates a pressure for countries to adopt emissions management systems—if a country wants to use more cost-effective cooperative approaches to achieve their NDCs, they will need to monitor carbon units for their economies.
Paragraphs 6.4-6.7 establish a mechanism "to contribute to the mitigation of greenhouse gases and support sustainable development". Though there is no specific name for the mechanism as yet, many Parties and observers have informally coalesced around the name "Sustainable Development Mechanism" or "SDM". The SDM is considered to be the successor to the Clean Development Mechanism, a flexible mechanism under the Kyoto Protocol, by which parties could collaboratively pursue emissions reductions for their Intended Nationally Determined Contributions. The Sustainable Development Mechanism lays the framework for the future of the Clean Development Mechanism post-Kyoto (in 2020).
In its basic aim, the SDM will largely resemble the Clean Development Mechanism, with the dual mission to 1. contribute to global GHG emissions reductions and 2. support sustainable development. Though the structure and processes governing the SDM are not yet determined, certain similarities and differences from the Clean Development Mechanism can already be seen. Notably, the SDM, unlike the Clean Development Mechanism, will be available to all parties as opposed to only Annex-1 parties, making it much wider in scope.
Since the Kyoto Protocol went into force, the Clean Development Mechanism has been criticized for failing to produce either meaningful emissions reductions or sustainable development benefits in most instances. It has also suffered from the low price of Certified Emissions Reductions (CERs), creating less demand for projects. These criticisms have motivated the recommendations of various stakeholders, who have provided through working groups and reports, new elements they hope to see in SDM that will bolster its success. The specifics of the governance structure, project proposal modalities, and overall design are expected to come during the next Conference of the Parties in Marrakesh.
Adaptation issues garnered more focus in the formation of the Paris Agreement. Collective, long-term adaptation goals are included in the Agreement, and countries must report on their adaptation actions, making adaptation a parallel component of the agreement with mitigation. The adaptation goals focus on enhancing adaptive capacity, increasing resilience, and limiting vulnerability.
At the Paris Conference in 2015 where the Agreement was negotiated, the developed countries reaffirmed the commitment to mobilize $100 billion a year in climate finance by 2020, and agreed to continue mobilizing finance at the level of $100 billion a year until 2025. The commitment refers to the pre-existing plan to provide US$100 billion a year in aid to developing countries for actions on climate change adaptation and mitigation.
Though both mitigation and adaptation require increased climate financing, adaptation has typically received lower levels of support and has mobilised less action from the private sector. A 2014 report by the OECD found that just 16 percent of global finance was directed toward climate adaptation in 2014. The Paris Agreement called for a balance of climate finance between adaptation and mitigation, and specifically underscoring the need to increase adaptation support for parties most vulnerable to the effects of climate change, including Least Developed Countries and Small Island Developing States. The agreement also reminds parties of the importance of public grants, because adaptation measures receive less investment from the public sector. John Kerry, as Secretary of State, announced that the U.S. would double its grant-based adaptation finance by 2020.
Some specific outcomes of the elevated attention to adaptation financing in Paris include the G7 countries' announcement to provide US $420 million for Climate Risk Insurance, and the launching of a Climate Risk and Early Warning Systems (CREWS) Initiative. In early March 2016, the Obama administration gave a $500 million grant to the "Green Climate Fund" as "the first chunk of a $3 billion commitment made at the Paris climate talks." So far, the Green Climate Fund has now received over $10 billion in pledges. Notably, the pledges come from developed nations like France, the US, and Japan, but also from developing countries such as Mexico, Indonesia, and Vietnam.
A new issue that emerged as a focal point in the Paris negotiations rose from the fact that many of the worst effects of climate change will be too severe or come too quickly to be avoided by adaptation measures. The Paris Agreement specifically acknowledges the need to address loss and damage of this kind, and aims to find appropriate responses. It specifies that loss and damage can take various forms—both as immediate impacts from extreme weather events, and slow onset impacts, such as the loss of land to sea-level rise for low-lying islands.
The push to address loss and damage as a distinct issue in the Paris Agreement came from the Alliance of Small Island States and the Least Developed Countries, whose economies and livelihoods are most vulnerable to the negative impacts of climate change. Developed countries, however, worried that classifying the issue as one separate and beyond adaptation measures would create yet another climate finance provision, or might imply legal liability for catastrophic climate events.
In the end, all parties acknowledged the need for "averting, minimizing, and addressing loss and damage" but notably, any mention of compensation or liability is excluded. The agreement also adopts the Warsaw International Mechanism for Loss and Damage, an institution that will attempt to address questions about how to classify, address, and share responsibility for loss and damage.
While each Party's NDC is not legally binding, the Parties are legally bound to have their progress tracked by technical expert review to assess achievement toward the NDC, and to determine ways to strengthen ambition. Article 13 of the Paris Agreement articulates an "enhanced transparency framework for action and support" that establishes harmonized monitoring, reporting, and verification (MRV) requirements. Thus, both developed and developing nations must report every two years on their mitigation efforts, and all parties will be subject to both technical and peer review.
While the enhanced transparency framework is universal, along with the global stocktaking to occur every 5 years, the framework is meant to provide "built-in flexibility" to distinguish between developed and developing countries' capacities. In conjunction with this, the Paris Agreement has provisions for an enhanced framework for capacity building. The agreement recognizes the varying circumstances of some countries, and specifically notes that the technical expert review for each country consider that country's specific capacity for reporting. The agreement also develops a Capacity-Building Initiative for Transparency to assist developing countries in building the necessary institutions and processes for complying with the transparency framework.
There are several ways in which flexibility mechanisms can be incorporated into the enhanced transparency framework. The scope, level of detail, or frequency of reporting may all be adjusted and tiered based on a country's capacity. The requirement for in-country technical reviews could be lifted for some less developed or small island developing countries. Ways to assess capacity include financial and human resources in a country necessary for NDC review.
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, there were enough countries that had ratified the agreement that produce enough of the world's greenhouse gases for the agreement to enter into force. The agreement went into effect on 4 November 2016.
Within the United Nations Framework Convention on Climate Change, legal instruments may be adopted to reach the goals of the convention. For the period from 2008 to 2012, greenhouse gas reduction measures were agreed in the Kyoto Protocol in 1997. The scope of the protocol was extended until 2020 with the Doha Amendment to that protocol in 2012.
During the 2011 United Nations Climate Change Conference, the Durban Platform (and the Ad Hoc Working Group on the Durban Platform for Enhanced Action) was established with the aim to negotiate a legal instrument governing climate change mitigation measures from 2020. The resulting agreement was to be adopted in 2015.
At the conclusion of COP 21 (the 21st meeting of the Conference of the Parties, which guides the Conference), on 12 December 2015, the final wording of the Paris Agreement was adopted by consensus by all of the 195 UNFCCC participating member states and the European Union to reduce emissions as part of the method for reducing greenhouse gas. In the 12 page Agreement, the members promised to reduce their carbon output "as soon as possible" and to do their best to keep global warming "to well below 2 degrees C" [3.6 degrees F].
The Paris Agreement was open for signature by States and regional economic integration organizations that are Parties to the UNFCCC (the Convention) from 22 April 2016 to 21 April 2017 at the UN Headquarters in New York.
The agreement stated that it would enter into force (and thus become fully effective) only if 55 countries that produce at least 55% of the world's greenhouse gas emissions (according to a list produced in 2015) ratify, accept, approve or accede to the agreement. On 1 April 2016, the United States and China, which together represent almost 40% of global emissions, issued a joint statement confirming that both countries would sign the Paris Climate Agreement. 175 Parties (174 states and the European Union) signed the agreement on the first date it was open for signature. On the same day, more than 20 countries issued a statement of their intent to join as soon as possible with a view to joining in 2016. With ratification by the European Union, the Agreement obtained enough parties to enter into effect as of 4 November 2016.
Both the EU and its member states are individually responsible for ratifying the Paris Agreement. A strong preference was reported that the EU and its 28 member states deposit their instruments of ratification at the same time to ensure that neither the EU nor its member states engage themselves to fulfilling obligations that strictly belong to the other, and there were fears that disagreement over each individual member state's share of the EU-wide reduction target, as well as Britain's vote to leave the EU might delay the Paris pact. However, the European Parliament approved ratification of the Paris Agreement on 4 October 2016, and the EU deposited its instruments of ratification on 5 October 2016, along with several individual EU member states.
As of December 2016, 194 states and the European Union have signed the Agreement. 160 of those parties have ratified or acceded to the Agreement, most notably China, the United States (who is intent on leaving) and India, the countries with three of the four largest greenhouse gas emissions of the signatories' total (about 42% together).

† Though corresponding with the source the provided number for Sierra Leone's emissions is incorrect. According to World Bank data, the correct 2000 emissions for Sierra Leone is 14,763 kt CO2-equivalents (not 365,107 kt), or 0.04% of the world total (not 0.98%).
The following UNFCCC member states were entitled to sign the Paris Agreement but did not do so prior to its close for signature on 21 April 2017. These states can now accede to the treaty. The Holy See is an observer state of the UNFCCC and can accede to the Paris Agreement if it first joins the UNFCC.
|State||Percentage of greenhouse
gases for ratification
|Holy See||N/A[d]||Observer state||The Holy See cannot sign the Paris Agreement until it becomes a full member of the UNFCCC. In 2015, Bernardito Auza stated that the Holy See intended to join the UNFCCC in order to sign the Paris Agreement.|
|Nicaragua||0.03%||Member state||In 2015, Nicaraguan envoy Paul Oquist criticized the Paris Agreement for not punishing countries who did not follow it. He stated Nicaragua will continue countering climate change on its own, with plans being that the country will be "90 percent renewable" by 2020.|
|Syria||0.21%||Member state||Syria was not expected to sign the Paris Agreement in 2015 due to the still ongoing Syrian Civil War.|
Article 28 of the agreement enables parties to withdraw from the agreement after sending a withdrawal notification to the depositary, but notice can be given no earlier than three years after the agreement goes into force for the country. Withdrawal is effective one year after the depositary is notified. Alternatively, the Agreement stipulates that withdrawal from the UNFCCC, under which the Paris Agreement was adopted, would also withdraw the state from the Paris Agreement. The conditions for withdrawal from the UNFCCC are the same as for the Paris Agreement.
On 1 June 2017, U.S. President Donald Trump announced that the United States would withdraw from the agreement. In accordance with Article 28, as the agreement entered into force in the United States on 4 November 2016, the earliest possible effective withdrawal date for the United States is 4 November 2020. If it chooses to withdraw by way of withdrawing from the UNFCCC, notice could be given immediately (the UNFCCC entered into force for the US in 1994), and be effective one year later. On August 4, 2017, the Trump Administration delivered an official notice to the United Nations that the U.S. intends to withdraw from the Paris Agreement as soon as it is legally eligible to do so. The formal notice of withdrawal cannot be submitted until the agreement is in force for 3 years for the US, in 2019.
According to a memo obtained by HuffPost believed to be written by US State Department legal office, any "attempts to withdraw from the Paris Agreement outside of the above-described withdrawal provisions would be inconsistent with international law and would not be accepted internationally."
In the agreement no provisions for non compliance are stated.
According to UNEP the emission cut targets in November 2016 will result in temperature rise by 3 °C above preindustrial levels, far above the 2 °C of the Paris climate agreement. Twenty years after the Kyoto Protocol fossil fuels are still humanity's primary energy source and consumption continues to grow.
A study published in the August 1, 2017 Nature found that all major industrialized nations are failing to meet the pledges they made in the Paris Agreement. In addition to failing to meet their reduction pledge amounts, the countries are not even enacting all the policies that they planned to do in order to meet their pledged reduction of CO2 output.
James Hansen called the Paris talks a fraud with 'no action, just promises' and feels that only an across the board tax on CO2 emissions, something not part of the Paris Agreement, would force CO2 emissions down fast enough to avoid the worst effects of global warming.
Although the agreement was lauded by many, including French President François Hollande and UN Secretary General Ban Ki-moon, criticism has also surfaced. For example, James Hansen, a former NASA scientist and a climate change expert, voiced anger that most of the agreement consists of "promises" or aims and not firm commitments.
Institutional asset owners associations and think-tanks have also observed that the stated objectives of the Paris Agreement are implicitly "predicated upon an assumption – that member states of the United Nations, including high polluters such as China, the US, India, Japan, Brazil, Canada, Russia, Indonesia and Australia, which generate more than half the world’s greenhouse gas emissions, will somehow drive down their carbon pollution voluntarily and assiduously without any binding enforcement mechanism to measure and control CO2 emissions at any level from factory to state, and without any specific penalty gradation or fiscal pressure (for example a carbon tax) to discourage bad behaviour."
World Pensions Council Director-General Nicolas J. Firzli insisted that, in reality, the role of government signatories would be limited in most instances, and that private sector asset owners would take the lead by expanding massively their investment in "clean tech, low-carbon ventures" and innovative companies which pursue socially and environmentally sound corporate strategies, regardless of whether the new US administration or other governments renege on their commitments.
The inevitable nature of the secular trend towards divestment from polluting fossil fuels was reconfirmed at 6th annual World Pensions Forum held in Greenwich in February 2017, with all institutional investors in attendance, including U.S. and Canadian pension funds, agreeing that climate-change conscious, responsible investments "constitute a [real, ] rising trend: [they’re] here to stay".
