The '''United Nations Framework Convention on Climate Change''' ('''UNFCCC''') is an [[International law|international]] [[Environmental protocol|environmental treaty]] negotiated at the [[Earth Summit]] in [[Rio de Janeiro]] from 3 to 14 June 1992, then entered into force on 21 March 1994. The UNFCCC objective is to "stabilize [[greenhouse gas]] concentrations in the atmosphere at a level that would prevent dangerous [[Human impact on the environment|anthropogenic interference]] with the [[climate system]]".<ref name="art2">{{cite web|url=http://unfccc.int/files/essential_background/background_publications_htmlpdf/application/pdf/conveng.pdf|title=Article 2|work=The United Nations Framework Convention on Climate Change|accessdate=23 May 2016}}</ref> The framework set no binding limits on greenhouse gas emissions for individual countries and contains no enforcement mechanisms. Instead, the framework outlines how specific international treaties (called "protocols" or "Agreements") may be negotiated to set binding limits on greenhouse gases.

Initially an Intergovernmental Negotiating Committee produced the text of the Framework Convention during its meeting in New York from 30 April to 9 May 1992. The UNFCCC was adopted on 9 May 1992, and opened for signature on 4 June 1992.<ref>{{citation|title=Status of Ratification of the Convention|publisher= United Nations Framework Convention on Climate Change |url= https://unfccc.int/essential_background/convention/status_of_ratification/items/2631.php |accessdate= 10 May 2015}}</ref> UNFCCC has 197 parties as of December 2015.

}} PDF version is also [http://www.smithschool.ox.ac.uk/wp-content/uploads/2011/03/Climate-Negotiations-report_Final.pdf available]</ref> The Protocol was amended in 2012 to encompass the period 2013-2020 in the Doha Amendment, which -as of December 2015- not entered into force. In 2015 the [[Paris Agreement]] was adopted, governing emission reductions from 2020 on through commitments of countries in ambitious Nationally Determined Contributions.

One of the first tasks set by the UNFCCC was for signatory nations to establish [[greenhouse gas inventory|national greenhouse gas inventories]] of [[greenhouse gas]] (GHG) emissions and removals, which were used to create the 1990 benchmark levels for accession of Annex I countries to the Kyoto Protocol and for the commitment of those countries to GHG reductions. Updated inventories must be regularly submitted by Annex I countries.

The UNFCCC is also the name of the [[United Nations Secretariat]] charged with supporting the operation of the Convention, with offices in [[Haus Carstanjen]], and UN Campus (known as [[Langer Eugen]]) [[Bonn, Germany]]. From 2010 to 2016 the head of the secretariat was [[Christiana Figueres]]. In July 2016, [[Patricia Espinosa]] from Mexico succeeded Figueres. The Secretariat, augmented through the parallel efforts of the [[Intergovernmental Panel on Climate Change]] (IPCC), aims to gain consensus through meetings and the discussion of various strategies.

== Treaty ==
The United Nations Framework Convention on Climate Change (UNFCCC) was opened for signature at the 1992 [[United Nations Conference on Environment and Development]] (UNCED) in [[Rio de Janeiro]] (known by its popular title, the [[Earth Summit]]). On 12 June 1992, 154 nations signed the UNFCCC, that upon ratification committed signatories' governments to reduce atmospheric concentrations of greenhouse gases with the goal of "preventing dangerous anthropogenic interference with Earth's climate system".  This commitment would require substantial reductions in greenhouse gas emissions (see the later section, [[United Nations Framework Convention on Climate Change#Stabilization of greenhouse gas concentrations|"Stabilization of greenhouse gas concentrations"]])

</ref> states that Parties should act to protect the climate system on the basis of "common but differentiated responsibilities", and that developed country Parties should "take the lead" in addressing climate change. Under Article 4, all Parties make general commitments to address climate change through, for example, climate change mitigation and adapting to the eventual impacts of climate change.<ref>

===Kyoto Protocol===
{{main article|Kyoto Protocol}}
After the signing of the UNFCCC treaty, Parties to the UNFCCC have met at conferences ("[[UNFCCC#Conferences of the Parties|Conferences of the Parties]]" – COPs) to discuss how to achieve the treaty's aims. At the [[UNFCCC#1995: COP 1, The Berlin Mandate|1st Conference of the Parties]] (COP-1), Parties decided that the aim of Annex I Parties stabilizing their emissions at 1990 levels by the year 2000 was "not adequate",<ref>

</ref> and further discussions at later conferences led to the [[Kyoto Protocol]]. The Kyoto Protocol sets emissions targets for developed countries which are binding under international law.

The Kyoto Protocol has had two commitment periods, the first of which lasted from 2008-2012. The second one runs from 2013-2020 and is based on the Doha Amendment to the Protocol, which has not entered into force.

The US has not ratified the Kyoto Protocol, while Canada denounced it in 2012. The Kyoto Protocol has been ratified by all the other Annex I Parties.

All Annex I Parties, excluding the US, have participated in the 1st Kyoto commitment period. 37 Annex I countries and the EU have agreed to second-round Kyoto targets. These countries are Australia, all members of the European Union, Belarus, Croatia, Iceland, Kazakhstan, Norway, Switzerland, and Ukraine.<ref>

===Paris Agreement===
{{main article|Paris Agreement}}
In 2011, parties adopted the "Durban Platform for Enhanced Action".<ref name="durban legal instrument">Paragraphs 2-4, in {{harvnb|COP|2012|p=2}}</ref> As part of the Durban Platform, parties have agreed to "develop a protocol, another legal instrument or an agreed outcome with legal force under the Convention applicable to all Parties".<ref name="durban legal instrument"/> At Durban<ref>{{harvnb|COP|2012|p=2}}</ref> and Doha,<ref>{{harvnb|COP|2013|p=19}}</ref> parties noted "with grave concern" that current efforts to hold global warming to below 2 or 1.5&nbsp;°C relative to the pre-industrial level appear inadequate.

In 2015, all (then) 196 then parties to the convention came together for the [[2015 United Nations Climate Change Conference|UN Climate Change Conference]] in Paris 30 November - 12 December and adopted by consensus the Paris Agreement, aimed at limiting global warming to less than two degrees Celsius, and pursue efforts to limit the rise to 1.5 degrees Celsius.<ref>{{Cite web|title = COP21 {{!}} United nations conference on climate change|url = http://www.cop21.gouv.fr/en/|website = www.cop21.gouv.fr|accessdate = 2015-12-07}}</ref> The [[Paris Agreement (climate change)|Paris Agreement]] is to be signed in 2016 and will enter into force upon ratification by 55 countries representing over 55% of greenhouse gas emissions.

=== Intended Nationally Determined Contributions ===
{{Main article|Intended Nationally Determined Contributions}}
At the [[2013 United Nations Climate Change Conference|19th session of the Conference of the Parties]] in Warsaw in 2013, the UNFCCC created a mechanism for [[Intended Nationally Determined Contributions|Intended Nationally Determined Contributions (INDCs)]] to be submitted in the run up to the [[2015 United Nations Climate Change Conference|21st session of the Conference of the Parties in Paris]] (COP21) in 2015.<ref>{{Cite news|url=http://climateobserver.org/open-and-shut/indc/|title=INDC - Climate Policy Observer|newspaper=Climate Policy Observer|language=en-US|access-date=2017-01-23}}</ref> Countries were given freedom and flexibility to ensure these climate change mitigation and adaptation plans were nationally appropriate;<ref>''[http://climateobserver.org/wp-content/uploads/2015/01/l05.pdf Ad Hoc Working Group on the Durban Platform for Enhanced Action Second session, part seven],'' UNFCCC, Geneva, 12 December 2014</ref> this flexibility, especially regarding the types of actions to be undertook, allowed for developing countries to tailor their plans to their specific adaptation and mitigation needs, as well as towards other needs.

In the aftermath of COP21, these INDCs became Nationally Determined Contributions (NDCs) when a country ratified the Paris Agreement, unless a new NDC was submitted to the UNFCCC at the same time.<ref>{{Cite web|url=http://unfccc.int/focus/ndc_registry/items/9433.php|title=NDC registry|last=Change|first=United Nations Framework Convention on Climate|website=unfccc.int|access-date=2017-01-23}}</ref> The [[2016 United Nations Climate Change Conference|22nd session of the Conference of the Parties]] (COP22) in Marrakesh focused on these Nationally Determined Contributions and their implementation, after the Paris Agreement entered into force on 4 November 2016.<ref>{{Cite web|url=https://treaties.un.org/pages/ViewDetails.aspx?src=TREATY&mtdsg_no=XXVII-7-d&chapter=27&clang=_en|title=United Nations Treaty Collection|language=EN|access-date=2017-01-23}}</ref>

The [[Climate and Development Knowledge Network]] (CDKN) created a guide for NDC implementation, for the use of decision makers in Less Developed Countries. In this guide, CDKN identified a series of common challenges countries face in NDC implementation, including how to: 
* build awareness of the need for, and benefits of, action among stakeholders, including key government ministries
* mainstream and integrate climate change into national planning and development processes
* strengthen the links between subnational and national government plans on climate change
* build capacity to analyse, develop and implement climate policy
* establish a mandate for coordinating actions around NDCs and driving their implementation
* address resource constraints for developing and implementing climate change policy.<ref>{{Cite web|url=http://www.cdkn.org/ndc-guide/|title=Planning for NDC implementation: A Quick-Start Guide|website=www.cdkn.org|language=en-GB|access-date=2017-01-23}}</ref>

===Other decisions===
In addition to the Kyoto Protocol (and its amendment) and the Paris Agreement, parties to the Convention have agreed to further commitments during UNFCCC Conferences of the Parties. These include the [[2007 United Nations Climate Change Conference|Bali Action Plan]] (2007),<ref>

;Copenhagen Accord and Cancún agreements
As part of the 2009 Copenhagen negotiations, a number of countries produced the [[Copenhagen Accord]].<ref name="copenhagen accord p5">
{{harvnb|COP|2010|p=5}}</ref> The Accord states that global warming should be limited to below 2.0&nbsp;°C (3.6&nbsp;°F).<ref name="copenhagen accord p5"/> This may be strengthened in 2015 with a target to limit warming to below 1.5&nbsp;°C.<ref name="copenhagen accord p7">{{harvnb|COP|2009|p=7}}, paragraph 12.</ref> The Accord does not specify what the baseline is for these temperature targets (e.g., relative to pre-industrial or 1990 temperatures). According to the UNFCCC, these targets are relative to pre-industrial temperatures.<ref>{{harvnb|UNFCCC|2012a}} (16 May)</ref>

114 countries agreed to the Accord.<ref name="copenhagen accord p5"/> The UNFCCC secretariat notes that "Some Parties [...] stated in their communications to the secretariat specific understandings on the nature of the Accord and related matters, based on which they have agreed to [the Accord]." The Accord was not formally adopted by the Conference of the Parties. Instead, the COP "took note of the Copenhagen Accord."<ref name="copenhagen accord p5"/>

As part of the Accord, 17 developed country Parties and the EU-27 have submitted mitigation targets,<ref>{{harvnb|UNFCCC|2011a}} (25 February)</ref> as have 45 developing country Parties.<ref>{{harvnb|UNFCCC|2012b}} (21 May)</ref> Some developing country Parties have noted the need for international support in their plans.

As part of the Cancún agreements, developed and developing countries have submitted mitigation plans to the UNFCCC.<ref>{{harvnb|UNFCCC|2011c}} (7 June)</ref><ref>{{harvnb|UNFCCC|2011b}} (18 March></ref> These plans are compiled with those made as part of the Bali Action Plan.

</ref> and Durban,<ref name="durban development">{{harvnb|COP|2012|p=9}}
</ref> the development needs of developing country parties were reiterated. For example, the Durban Platform reaffirms that:<ref name="durban development"/><blockquote>[...] social and economic development and poverty eradication are the first and overriding priorities of developing country Parties, and that a low-emission development strategy is central to sustainable development, and that the share of global emissions originating in developing countries will grow to meet their social and development needs</blockquote>

=== Interpreting Article 2 ===
{{Further information|Avoiding dangerous climate change}}
The ultimate objective of the Framework Convention is to prevent "dangerous" anthropogenic (i.e., human-caused) interference of the climate system.<ref name=art2/> As is stated in Article 2 of the Convention, this requires that GHG concentrations are stabilized in the atmosphere at a level where [[climate change and ecosystems|ecosystems]] can adapt naturally to climate change, [[climate change and agriculture|food production]] is not threatened, and [[economics of global warming|economic development]] can proceed in a sustainable fashion.

=== Precautionary principle ===
In decision making, the [[precautionary principle]] is considered when possibly dangerous, irreversible, or catastrophic events are identified, but scientific evaluation of the potential damage is not sufficiently certain (Toth ''et al''., 2001, pp.&nbsp;655–656).<ref name="2001 toth precautionary principle">{{cite book | year = 2001 | contribution = 10.4.2.2 Precautionary Considerations | title = Chapter 10. Decision-making Frameworks | series = Climate Change 2001: Mitigation: Contribution of Working Group III to the Third Assessment Report of the Intergovernmental Panel on Climate Change | editor = B. Metz| publisher = Cambridge University Press | author = Toth, F.L.| url = http://www.grida.no/climate/ipcc_tar/wg3/437.htm |display-authors=etal|display-editors=etal}}</ref> The precautionary principle implies an emphasis on the need to prevent such adverse effects.

Uncertainty is associated with each link of the causal chain of climate change. For example, future GHG emissions are uncertain, as are climate change damages. However, following the precautionary principle, uncertainty is not a reason for inaction, and this is acknowledged in Article 3.3 of the UNFCCC (Toth ''et al''., 2001, p.&nbsp;656).<ref name="2001 toth precautionary principle"/>

* '''Annex B''': Parties listed in Annex B of the Kyoto Protocol are Annex I Parties with first- or second-round Kyoto greenhouse gas emissions targets (see [[Kyoto Protocol]] for details). The first-round targets apply over the years 2008–2012. As part of the [[2012 United Nations Climate Change Conference|2012 Doha climate change talks]], an amendment to Annex B was agreed upon containing with a list of Annex I Parties who have second-round Kyoto targets, which apply from 2013–2020.<ref>

== Conferences of the Parties ==
{{main article|United Nations Climate Change conference}}
The United Nations Climate Change Conference are yearly conferences held in the framework of the UNFCC. They serve as the formal meeting of the UNFCC Parties (''Conferences of the Parties'') (COP) to assess progress in dealing with climate change, and beginning in the mid-1990s, to negotiate the [[Kyoto Protocol]] to establish legally binding obligations for developed countries to reduce their greenhouse gas emissions.<ref name="climate-leaders.org"/> From 2005 the Conferences have also served as the [[Meetings of Parties of the Kyoto Protocol (CMP)]]. Also parties to the Convention that are not parties to the Protocol can participate in Protocol-related meetings as observers. The first conference (COP1) was held in 1995 in Berlin. The 3rd conference (COP3) was held in Kyoto and resulted in the Kyoto protocol, which was amended during the [[2012 United Nations Climate Change Conference|2012 Doha]] Conference (COP18, CMP 8). The latest Conference (COP21, CMP11) was held in Paris and resulted in adoption of the Paris Agreement. The next conference is planned November 2016 in Marrakech, Morocco.

== Subsidiary bodies ==
A subsidiary body is a committee that assists the Conference of the Parties. Subsidiary bodies include:<ref>{{cite web | url = http://unfccc.int/essential_background/glossary/items/3666.php | title = Glossary of climate change acronyms | work = Essential Background | publisher = UNFCCC.int | accessdate = 23 August 2016 }}</ref>
* Permanents:
** The [[Subsidiary Body of Scientific and Technological Advice]] (SBSTA) is established by Article 9 of the Convention to provide the Conference of the Parties and, as appropriate, its other subsidiary bodies with timely information and advice on scientific and technological matters relating to the Convention. It serves as a link between information and assessments provided by expert sources (such as the [[Intergovernmental Panel on Climate Change|IPCC]]) and the COP, which focuses on setting policy.
** The [[Subsidiary Body of Implementation]] (SBI) is established by Article 10 of the Convention to assist the Conference of the Parties in the assessment and review of the effective implementation of the Convention. It makes recommendations on policy and implementation issues to the COP and, if requested, to other bodies.
* Temporary:
** Ad hoc Group on Article 13 (AG13), active from 1995 to 1998;
** Ad hoc Group on the Berlin Mandate (AGBM), active from 1995 to 1997;
** [[Ad Hoc Working Group on Further Commitments for Annex I Parties under the Kyoto Protocol]] (AWG-KP), established in 2005 by the Parties to the Kyoto Protocol to consider further commitments of industrialized countries under the Kyoto Protocol for the period beyond 2012; it concluded its work in 2012 when the CMP adopted the [[2012 United Nations Climate Change Conference|Doha Amendment]];<ref>{{cite web | url = http://unfccc.int/bodies/body/6409.php | title = What is the AWG-KP? | publisher = UNFCCC.int | accessdate = 23 August 2016 }}</ref>
** [[Ad Hoc Working Group on Long-term Cooperative Action]] (AWG-LCA), established in Bali in 2007 to conduct negotiations on a strengthened international deal on climate change;
** [[Ad Hoc Working Group on the Durban Platform for Enhanced Action]] (ADP), established at [[2011 United Nations Climate Change Conference|COP 17 in Durban]] in 2011 "to develop a protocol, another legal instrument or an agreed outcome with legal force under the Convention applicable to all Parties." <ref>{{cite web | url = http://unfccc.int/resource/docs/2011/cop17/eng/09a01.pdf#page=2 | title = Establishment of an Ad Hoc Working Group on the Durban Platform for Enhanced Action | work = Decision 1/CP.17 | publisher = UNFCCC.int | accessdate = 23 August 2016}}</ref> The ADP concluded its work in Paris on 5 December 2015.<ref>{{cite web | url = http://unfccc.int/bodies/body/6645.php | title = What is the ADP? | publisher = UNFCCC.int | accessdate = 23 August 2016 }}</ref>

== Secretariat ==
The work under the UNFCCC is facilitated by a secretariat in [[Bonn]], Germany. The secretariat is established under Article 8 of the Convention. It is headed by the Executive Secretary. The current Executive Secretary, [[Patricia Espinosa]], was appointed on 18 May 2016 by United Nations Secretary-General [[Ban Ki-moon]] and took office on 18 July 2016.<ref>{{cite web|title=Executive Secretary|url=http://unfccc.int/secretariat/executive_secretary/items/1200.php|website=unfccc.int|accessdate=28 August 2016}}</ref> She succeeded [[Christiana Figueres]] who held the office since 2010. Former Executive Secretaries have been [[Yvo de Boer]] (2006-2010), [[Joke Waller-Hunter]] (2002-2005) and [[Michael Zammit Cutajar]] (1995-2002).

== Action for climate empowerment (ACE) ==
''Main article: [[Action for climate empowerment (ACE)]]''

Action for Climate Empowerment (ACE) is a term adopted by the UNFCCC. It refers to Article 6 of the Convention’s original text (1992), focusing on six priority areas: education, training, public awareness, public participation, public access to information, and international cooperation on these issues. The implementation of all six areas has been identified as the pivotal factor for everyone to understand and participate in solving the complex challenges presented by [[climate change]]. ACE calls on governments to develop and implement educational and public awareness programmes, train scientific, technical and managerial personnel, foster access to information, and promote public participation in addressing climate change and its effects. It also urges countries to cooperate in this process, by exchanging good practices and lessons learned, and strengthening national institutions. This wide scope of activities is guided by specific objectives that, together, are seen as crucial for effectively implementing climate adaptation and mitigation actions, and for achieving the ultimate objective of the UNFCCC.<ref name=":0">{{Cite book|url=http://unesdoc.unesco.org/images/0024/002464/246435e.pdf|title=Action for climate empowerment: Guidelines for accelerating solutions through education, training and public|last=UNESCO and UNFCCC|first=|publisher=UNESCO and UNFCCC|year=2016|isbn=978-92-3100-182-6|location=|pages=6}}</ref>

==Commentaries and analysis==

===Criticisms of the UNFCCC Process===
The overall umbrella and processes of the UNFCCC and the adopted Kyoto Protocol have been criticized by some as not having achieved its stated goals of reducing the emission of [[carbon dioxide]] (the primary culprit blamed for rising global temperatures of the 21st century).<ref>{{cite web|title=The Kyoto Protocol: Hot air|url=http://www.nature.com/news/the-kyoto-protocol-hot-air-1.11882|work=Nature|accessdate=29 November 2012}}</ref> At a speech given at his alma mater, Todd Stern&nbsp;— the US Climate Change envoy&nbsp;— has expressed the challenges with the UNFCCC process as follows, “Climate change is not a conventional environmental issue...It implicates virtually every aspect of a state's economy, so it makes countries nervous about growth and development. This is an economic issue every bit as it is an environmental one.”  He went on to explain that, the United Nations Framework Convention on Climate Change is a multilateral body concerned with climate change and can be an inefficient system for enacting international policy. Because the framework system includes over 190 countries and because negotiations are governed by consensus, small groups of countries can often block progress.<ref>{{cite web|title="Voices" speaker talks climate change |url=http://thedartmouth.com/2012/08/03/news/climate|publisher=The Dartmouth|accessdate=29 November 2012}}</ref>

The failure to achieve meaningful progress and reach effective-CO2 reducing-policy treaties among the parties over the past eighteen years have driven some countries like the United States to never ratify the UNFCCC's largest body of work&nbsp;— the Kyoto Protocol, in large part because the treaty didn't cover developing countries who now include the largest CO2 emitters. However, this fails to consider the historical responsibility for climate change since industrialisation, which is a contentious issue in the talks, and the responsibility of emissions from consumption and importation of goods.<ref>{{cite news|title=Which nations are most responsible for climate change? |url=https://www.theguardian.com/environment/2011/apr/21/countries-responsible-climate-change|publisher=Guardian|accessdate=2 January 2013|location=London|first=Duncan|last=Clark|date=21 April 2011}}</ref> It has also led Canada to withdraw from the Kyoto Protocol out of a desire to not force its citizens to pay penalties that would result in wealth transfers out of Canada. Canada formally withdrew from the Kyoto Protocol in 2011.<ref>{{cite news|title=Canada pulls out of Kyoto Protocol |url=http://www.cbc.ca/news/politics/story/2011/12/12/pol-kent-kyoto-pullout.html|publisher=CBC News|accessdate=29 November 2012}}</ref> Both the US and Canada are looking at [[Voluntary Emissions Reduction]] schemes that they can implement internally to curb carbon dioxide emissions outside the Kyoto Protocol.<ref>{{cite news|title=U.N.

The perceived lack of progress has also led some countries to seek and focus on alternative high-value activities like the creation of the [[Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants]] which seeks to regulate short-lived pollutants such as methane, [[black carbon]] and [[hydrofluorocarbon]]s (HFCs) which together are believed to account for up to 1/3 of current global warming but whose regulation is not as fraught with wide economic impacts and opposition.<ref>{{cite web|title=Secretary Clinton To Announce a Climate and Clean Air Initiative To Reduce Short-Lived Climate Pollutants|url=http://www.state.gov/r/pa/prs/ps/2012/02/184011.htm|publisher= US Dept of State|accessdate=29 November 2012}}</ref>

In 2010, Japan stated that it will not sign up to a second Kyoto term, because it would impose restrictions on it not faced by its main economic competitors, China, India and Indonesia.<ref>{{cite news|title=Japan derails climate talks by refusing to renew Kyoto treaty |url=http://www.independent.co.uk/environment/climate-change/japan-derails-climate-talks-by-refusing-to-renew-kyoto-treaty-2148769.html|work=The Independent|accessdate=29 November 2012|location=London|first=Michael|last=McCarthy|date=2 December 2010}}</ref> A similar indication was given by the Prime Minister of New Zealand in November 2012.<ref>{{cite news|title=NZ backs off Kyoto climate change route|url=http://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=10846305|work=The New Zealand Herald|accessdate=29 November 2012|date=10 November 2012}}</ref> At the 2012 conference, last minute objections at the conference by Russia, [[Ukraine]], [[Belarus]] and [[Kazakhstan]] were ignored by the governing officials, and they have indicated that they will likely withdraw or not ratify the treaty.<ref name="Belarus negotiator hints at Kyoto exit, says others could follow

</ref> These defections place additional pressures on the UNFCCC process that is seen by some as cumbersome and expensive: in the UK alone the climate change department has taken over 3,000 flights in two years at a cost of over [[₤]]1,300,000 (British Pounds).<ref>{{cite web|title=UK climate change department takes over 3000 flights at a cost of over £1.3m|url=http://www.thecommentator.com/article/1920/uk_climate_change_department_takes_over_3000_flights_at_a_cost_of_over_1_3m|publisher=The Commentator|accessdate=29 November 2012}}</ref>

Before the [[2015 United Nations Climate Change Conference]], [[National Geographic Magazine]] added criticism, writing: "Since 1992, when the world’s nations agreed at Rio de Janeiro to avoid 'dangerous anthropogenic interference with the climate system,' they’ve met 20 times without moving the needle on carbon emissions. In that interval we’ve added almost as much carbon to the atmosphere as we did in the previous century."<ref>[http://ngm.nationalgeographic.com/print/2015/11/climate-change/introduction-text Fresh Hope for Combating Climate Change], National Geographic, November 2015, page 14 of print edition</ref>

===Benchmarking===
[[Benchmarking]] is the setting of a policy target based on some frame of reference.<ref>

</ref> commented on the economic implications of this target. Although the target applies equally to all Annex I Parties, the economic costs of meeting the target would likely vary between Parties. For example, countries with initially high levels of [[efficient energy use|energy efficiency]] might find it more costly to meet the target than countries with lower levels of energy efficiency. From this perspective, the UNFCCC target could be viewed as [[equity (economics)|inequitable]], i.e., unfair.

Benchmarking has also been discussed in relation to the first-round emissions targets specified in the [[Kyoto Protocol]] (see [[views on the Kyoto Protocol]] and [[Kyoto Protocol and government action]]).
