The first UNFCCC Conference of the Parties occurred from 28 March to 7 April 1995 in Berlin, Germany. It voiced worries about the sufficiency of nations' capacities to meet responsibilities under the Body for Scientific and Technological Advice (BSTA) and the Subsidiary Body for Implementation (SBI). COP 1 settled on "Exercises Implemented Jointly", first joint estimates in global environment activity.

COP 2 occurred in July 1996 in Geneva, Switzerland. Its ministerial announcement was noted (but not adopted) on 18 July 1996, and mirrored a United States position statement introduced by Timothy Wirth, previous Under Secretary for Global Affairs for the United States Department of State at that gathering.

COP 3 was held in Kyoto, Japan from 4 - 15 November 1997. During this conference, the Kyoto Protocol is adopted with the obligation to diminish emissions of greenhouse gases in industrialized nations. It establishes the foundation of the carbon market.

COP 4 took place in November 1998 in Buenos Aires. It had been expected that the issues unresolved in Kyoto COP 3 would be settled at this conference. However, the intricacy and trouble of finding agreement on these issues proved insurmountable, and on second thought the parties adopted a 2-year "Strategy" to propel endeavors and to devise systems for executing the Kyoto Protocol, to be finished by 2000. During COP4, Argentina and Kazakhstan expressed their commitment to take on the greenhouse gas emissions reduction commitment.

COP 5 that was held between 25 October and 5 November 1999, in Bonn, Germany was mainly a technical conference. This year, the conference did not reach any major conclusions.

COP 6 was held on 13–25 November 2000, in The Hague, Netherlands. The conversations developed quickly into a significant level discussion over the major political issues. These included significant discussion over the United States' proposition to permit credit for carbon "sinks" in forests and farming grounds that would fulfill a significant extent of the U.S. emissions reductions along these lines; conflicts over consequences non-compliance by countries that didn't meet their reduction targets; and difficulties in settling how developing nations could acquire financial assistance to manage unfriendly impacts of environmental change and meet their commitments to make arrangements plan for measuring and possibly reducing greenhouse gas emissions.

At the COP 7 meeting held in Marrakech, Morocco from 29 October to 10 November 2001, negotiators wrapped up the work on the Buenos Aires Plan of Action, finishing the majority of the functional details and making way for countries to endorse the Kyoto Protocol. The completed package of choices is known as the Marrakesh Accords.

The United States delegation kept up with its onlooker job, declining to take part effectively in the negotiations. Other parties hoped that the United States would re-engage in the process and worked to achieve confirmation of the Kyoto Protocol by the required number of nations to bring it into force.

This meeting was held from 23 October to 1 November 2002, in New Delhi. COP 8 adopted the Delhi Ministerial Declaration calling for endeavors by developed nations to move innovation and limit the effect of environmental change on developing countries. It additionally approved the New Delhi work program on Article 6 of the Convention

The COP8 was marked by Russia's hesitation, expressing that it required additional opportunity to thoroughly consider it. The Kyoto Protocol could go into force whenever it was approved by 55 nations, including nations answerable for 55% of the developed world's 1990 carbon dioxide emanations. With the United States (36.1 percent of created world carbon dioxide) and Australia refusing ratification, Russia's understanding (17% of worldwide outflows in 1990) was expected to meet the approval measures and thus Russia could delay the cycle.

COP 9 was held from 1-12 December 2003 in Milan.

It was one of the biggest intergovernmental conferences on environmental change of all time.

The event marked the section into power of the Kyoto Protocol. Facilitating in excess of 10,000 delegates, it was one of Canada's biggest global occasions ever and the biggest get-together in Montreal since Expo 67.

Canada's environment minister, at that point, Stéphane Dion, said the understanding gives a future map.

COP 12/CMP 2 held on 6 -17 November 2006 in Nairobi, Kenya. At the meeting, BBC reporter Richard Black instituted the saying "climate tourists" to describe a few representatives who joined in "to see Africa, take snaps of the untamed life, poor people, dying African children and women".

Black also noted that there were no discussions related to reducing emissions. The meeting showed a strong disconnection between the scientific imperative and the political process. In spite of such analysis, certain steps were made at COP12, remembering the areas of help for support for developing countries and clean advancement components. The parties adopted a five-year plan of work to help environmental change transformation by developing countries, and settled on the methodology and modalities for the Adaptation Fund. They also consented to work on the undertakings for a clean development mechanism.

COP 15 took place in Copenhagen, Denmark, on 7-18 December 2009.The general objective for the COP 15/CMP 5 United Nations Climate Change Conference in Denmark was to lay out an ambitious global climate agreement for the period from 2012 when the first commitment period under the Kyoto Protocol lapsed. On 14 November 2009, the New York Times declared that "President Obama and other world pioneers have chosen to put off the difficult undertaking of arriving at an environmental change agreement... concurring rather to make it the mission of the Copenhagen conference to arrive at a less specific "politically restricting" agreement that would dropkick the most difficult issues into what's in store".

COP 16 was held in Cancun, Mexico, from 28 November to 10 December 2010. The result of the summit was a contract taken on by the states' parties that required the US $100 billion for every annum "Green Climate Fund", and a "Climate Technology Center" and organization. Anyway the subsidizing of the Green Climate Fund was not settled upon. Nor was a pledge to a second time of the Kyoto Protocol agreed upon, however it was reasoned that the base year will be 1990 and the global warming potentials will be those given by the IPCC. All parties perceiving that environmental change addresses a pressing and possibly irreversible danger to human societies and the planet, and accordingly expects to be earnestly addressed by all Parties.

The 2011 COP 17 was held in Durban, South Africa, from 28 November to 9 December 2011.The meeting agreed to beginning negotiations on a legitimately official arrangement comprising all nations, to be taken on in 2015, overseeing the period post 2020. There was also progress in regards to the making of a Green Climate Fund (GCF) for which an administration structure was embraced. The fund is to distribute US$100 billion every year to assist poor nations with adjusting to environmental influences. While the president of the conference, Maite Nkoana-Mashabane, proclaimed it a triumph, researchers and environmental groups cautioned that the agreement was not adequate to avoid an unnatural weather change past 2 °C as a more urgent act is required.

Qatar facilitated COP 18 which occurred in Doha, Qatar, from 26 November to 7 December 2012. The Conference produced a bundle of documents on the whole named The Doha Climate Gateway. The meeting gained little headway towards subsidizing the Green Climate Fund. Russia, Belarus and Ukraine protested toward the finish of the session, as they reserved a privilege to under the session's rules. In closing the meeting, the President said that he would take note of these protests in his final report.
