COP28. An overview of the UN climate change summits – Vatican News

As Pope Francis prepares to speak at COP28 in Dubai, running from 30 November to 12 December, we offer a general overview of the United Nations climate change conferences and their outcomes.

By Vatican News

COP (Conference of the Parties) is the supreme decision-making body of the United Nations Framework Convention on Climate Change (UNFCCC), which was adopted in 1992 at the UN Conference on Environment and Development (UNCED), known as the “Earth Summit”, held in Rio de Janeiro (Brazil) shortly after the first assessment report issued in 1990 by the Intergovernmental Panel on Climate Change (IPCC).

The panel includes the world’s leading climate scientists who in the past decades have provided policymakers with regular, comprehensive, and authoritative scientific assessments on climate science knowledge, and specifically on the link between climate change and human activities, building on the work of thousands of scientists worldwide.

Based on the first IPCC Report, the 1992 UN Convention established an international environmental treaty to combat “dangerous human interference with the climate system”, in part by stabilizing greenhouse gas concentrations in the atmosphere, though it did not bind signatories to reduce emissions and gave no targets or timetables for doing so. However, it required frequent meetings between the ratifying countries, known as the above-mentioned Conferences of the Parties.

The Convention was originally signed by 154 states. As of 2023 it has been ratified by 198 countries.

Since entering into force in 1994, the UNFCCC has provided the basis for international climate negotiations. Starting from 1995, when the first COP was held in Berlin (Germany), Parties have met every year to measure progress and negotiate multilateral responses to climate change.

Two landmark agreements

Negotiations have resulted in two landmark agreements: the Kyoto Protocol (1997) requiring developed countries to reduce emissions, and the Paris Agreement (2015), in which, after 25 years of difficult negotiations, 196 parties pledged to reduce their greenhouse gas emissions, with enhanced support to assist developing countries to do so.

Its central aim is to strengthen the global response to the threat of climate change by keeping a global temperature rise this century well below 2 degrees Celsius above pre-industrial levels, and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius.

Although the U.S. originally signed the agreement, the Trump Administration pulled out in 2017. U.S President Joe Biden re-entered the United States in the Agreement in 2021, soon after his election.  However, since the adoption of the Paris Agreement progress in its implementation, namely in reducing emissions, has been slow.

Another major breakthrough came from COP -27 in  Sharm el-Sheikh in 2022 which established the Loss and Damage Fund, aimed to provide financial assistance to poorer nations as they deal with the negative consequences that arise from the unavoidable risks of climate change (rising sea levels, extreme heat waves, desertification, forest fires, crop failures etc.).

The funding will help vulnerable nations to rebuild the necessary physical and social infrastructure. While the fund is undoubtedly a historic breakthrough, its success largely depends on how quickly nations are able to get the fund up and running.

The COP-28 to be held in Dubai , United Arab Emirates,  from November 30 to December 12, 2023, will carry out the first global assessment of the Paris Agreement. The question of fossil fuels will once again be at the heart of discussions.

Timeline*

1992-1994 – The ground-breaking Rio Earth Summit and the UNFCCC

The summit results in some of the first international agreements on climate change, which become the foundation for future accords. Among them is the UN Framework Convention on Climate Change (UNFCCC) which aims to prevent “dangerous” human interference in the climate system, acknowledges that human activities contribute to climate change, and recognizes climate change as an issue of global concern. The UNFCCC, which went into force in 1994, does not legally bind signatories to reduce greenhouse gas emissions and gives no targets or timetables for doing so. But it requires frequent meetings between the ratifying countries, known as the Conference of the Parties, or COP. As of 2023 it has been ratified by 198 countries.

1995 – First meeting of UNFCCC signatories in Berlin (COP1)

UNFCCC signatories gather for the first Conference of the Parties, or COP1, in Berlin. The United States pushes back against legally binding targets and timetables, but it joins other parties in agreeing to negotiations to strengthen commitments on limiting greenhouse gases. The concluding document, known as the Berlin Mandate lays the groundwork for what will be the Kyoto Protocol, but it is criticized by environmental activists as a political solution that does not prompt immediate action.

1997 Kyoto Protocol, first legally binding climate treaty adopted at COP23

At COP3 in Japan, the conference adopts the Kyoto Protocol The legally binding treaty requires developed countries to reduce emissions by an average of 5 percent below 1990 levels and establishes a system to monitor countries’ progress. But the protocol does not compel developing countries, including high carbon emitters China and India, to take action. It also creates a carbon market for countries to trade emissions units and encourage sustainable development, a system known as “cap and trade.” Countries must now work out the details of implementing and ratifying the protocol.

2001 – Breakthrough in Bonn, but without the U.S.

The Kyoto Protocol is in jeopardy after talks collapse in November 2000 and the United States withdraws in March 2001, with Washington (pressurized by petroleum lobbies) saying that the protocol is not in the country’s “economic best interest.” In July 2001, negotiators in Bonn, Germany, reach breakthroughs on green technology, agreements on emissions trading, and compromises on how to account for carbon sinks (natural reservoirs that take in more carbon than they release). In October, countries agree on the rules for meeting targets set by the Kyoto Protocol, paving the way for its entry into force.

2005 –  The Kyoto Protocol takes effect

The Kyoto Protocol enters into force in February after it is ratified by enough countries to account for at least 55 percent of global emissions. Notably, it does not include the United States, the world’s leading carbon emitter. Between 2008 and 2012, when the protocol is set to expire, countries are supposed to reduce emissions by their pledged amounts: the European Union commits to reduce emissions by 8 percent below 1990 levels, Japan commits to 5 percent, and Russia commits to keeping levels steady with 1990 levels.

2007 – Negotiations begin for Kyoto 2.0

Before COP13 in Bali, Indonesia, the UN Intergovernmental Panel on Climate Change (IPCC) releases a new strongly-worded report yet confirming that global warming is “most likely” caused by human activity. During the conference, discussions begin on a stronger successor to the Kyoto Protocol. But they come to a standstill after the United States objects to a widely backed proposal that calls for all industrialized nations to cut greenhouse gas emissions by specific targets. U.S. officials argue that developing countries must also make commitments. Washington eventually backs down, and the parties adopt the Bali Action Plan, which establishes the goal of drafting a new climate agreement by 2009.

September 2009 –  U.S. joins bold statements at UN

Three months ahead of the target date for a new agreement, several world leaders pledge actions during a UN summit on climate change hosted by Secretary-General Ban Ki-moon. Chinese President Hu Jintao announces a plan to cut emissions by a “notable margin” by 2020, marking the first time Beijing commits to reducing its rate of greenhouse gas emissions. Japanese Prime Minister Yukio Hatoyama pledges to reduce emissions by 25 percent. U.S. newly elected President Barack Obama, in his first UN address, says the United States is determined to act and lead, but he doesn’t offer any new proposals. Ban expresses hope that leaders will reach a “substantive deal” during the upcoming conference in Copenhagen.

December 2009 – Disappointment at COP15 in Copenhagen (Denmark)

The successor to the Kyoto Protocol is supposed to be finalized at COP15 in Copenhagen, but the parties only come up with a nonbinding document that is “taken note of,” not adopted. The Copenhagen Accord acknowledges that global temperatures should not increase by 2°C (3.6°F) above preindustrial levels, though representatives from developing countries sought a target of 1.5°C (2.7°F). (A 2009 report from the American Meteorological Society predicts a 3.5°C [6.3°F] to 7.4°C [13.3°F] increase in less than one hundred years). After leading the negotiations, U.S. President Barack Obama tells the conference that the accord is “not enough.” Some countries later vow to follow the accord—though it remains non-binding—and make their own pledges.

2010  Temperature target set at COP16 in Cancun (Mexico)

There is increased pressure to reach a consensus in Mexico during COP16 after the failure in Copenhagen and NASA’s announcement that 2000–2009 was the warmest decade ever recorded. Countries commit for the first time to keep global temperature increases below 2°C in the Cancun Agreements. Approximately eighty countries, including China, India, and the United States, as well as the European Union, submit emissions reduction targets and actions, and they agree on stronger mechanisms for monitoring progress. But analysts say it’s not enough to stay below the 2°C target. The Green Climate Fund, a $100 billion fund to assist developing countries in mitigating and adapting to climate change, is also established. As of 2019, only around $3 billion has been contributed.

2011- New accord at COP17 to apply to all countries

The conference in Durban, South Africa, nearly fails after the world’s three biggest polluters—China, India, and the United States—reject an accord proposed by the European Union. But they eventually agree to work toward drafting a new, legally binding agreement in 2015 at the latest. The new agreement will differ from the Kyoto Protocol in that it will apply to both developed and developing countries. With the Kyoto Protocol set to expire in a few months, the parties agree to extend it until 2017.

2012 – No deal at COP 18 in Doha

Negotiators in Doha for COP18 extend the Kyoto Protocol until 2020, but remaining participants account for just 15 percent of global greenhouse gas emissions. By this time, Canada has withdrawn from the treaty, and Japan and Russia say they will not accept new commitments. (The United States never signed on.) Environmental groups criticize countries for not reaching an effective agreement as Typhoon Bopha slams the Philippines, which they say exemplifies a rise in extreme weather caused by climate change. One of the conference’s successes is the Doha Amendment, under which developed countries agree to assist developing countries mitigate and adapt to the effects of climate change. The agreement also sets delegates on the path toward a new treaty.

2013  – G77’s lead negotiators walk out at COP19 in Warsaw (Poland)

During the first week of COP19 in Poland, a grouping of developing countries, known as the Group of Seventy-Seven (G77), and China propose a new funding mechanism to help vulnerable countries deal with “loss and damage” caused by climate change. Developed countries oppose the mechanism, so the G77’s lead negotiators walk out of the conference. Talks eventually resume, and governments agree to a mechanism that falls short of what developing countries wanted. Countries also agree on how to implement an initiative to end deforestation known as REDD+, but the conference is described by analysts as the “least consequential COP in several years”.

2015 – Landmark Paris Agreement reached

196  countries agree to what experts call the most significant global climate agreement in history, known as the Paris Agreement. Unlike past accords, it requires nearly all countries—both developed and developing—to set emissions reduction goals. However, countries can choose their own targets and there are no enforcement mechanisms to ensure they meet them. Under the agreement, countries are supposed to submit targets known as nationally determined contributions (NDCs). The mission of the Paris Agreement, which enters into force in November 2016, is to keep global temperature rise below 2°C and pursue efforts to keep it below 1.5°C. But analysts urge more action to achieve this goal. In 2017, President Donald J. Trump withdraws the United States from the agreement, saying that it imposes “draconian financial and economic burdens” on the country.

2018 – Rules for Paris Agreement decided

Just ahead of COP24 in Katowice, Poland, a new IPCC report warns of devastating consequences—including stronger storms and dangerous heat waves—if the average global temperature rises 1.5°C above preindustrial levels and projects that it could reach that level by 2030. Despite the report, countries do not agree to stronger targets. They do, however, largely settle on the rules for implementing the Paris accord, covering questions including how countries should report their emissions. They do not agree on rules for carbon trading, however, and push that discussion to 2019.

September 2019- UN General Secretary plans Climate Action Summit

UN Secretary-General Antonio Guterres organizes the UN Climate Action Summit for world leaders in New York. Countries are mandated by the Paris Agreement to submit revised NDCs by the following year, so the meeting is a chance for leaders to share their ideas. But leaders of the world’s top carbon-emitting countries, including the United States and China, do not attend. At the summit, Guterres asks countries to submit plans to cut greenhouse gas emissions by 45 percent by 2030 and reach carbon neutrality by 2050.

December 2019- Lack of progress at COP25 in Madrid (Spain)

COP25 is marked by a lack of progress on major climate issues despite a year of dire warnings from scientists, record heatwaves, and worldwide protests demanding action. Negotiators are unable to finalize rules for a global carbon market, and they disagree over whether to compensate developing countries devastated by effects of climate change including rising sea levels and extreme weather. The conference’s final declaration does not explicitly call on countries to increase their climate pledges made under the Paris Agreement, and Secretary-General Guterres describes the talks as a lost opportunity.

April 2020 – Talks postponed amid COVID-19 pandemic

The United Nations postpones COP26, originally scheduled for November 2020, until 2021 because of a pandemic of a new coronavirus disease, known as COVID-19. Countries were expected to strengthen their emissions reduction goals set under the Paris Agreement at the conference in Glasgow. Amid the pandemic, emissions fall worldwide as many countries implement nationwide shutdowns that drastically slow economic activity. But experts predict that the reductions won’t last, with governments under pressure to boost output and disregard the environment to save their struggling economies.

July 2021 – States  update pledges ahead of COP26 in Glasgow (Scotland)

More than one hundred countries, altogether accounting for nearly 60 percent of Paris Agreement signatories, meet the deadline to submit updated NDCs ahead of COP26 in November. Some of the top emitters propose more ambitious targets. President Joe Biden announces that the United States will aim to cut its emissions to roughly half of its 2005 level by 2030, doubling President Obama’s commitment. Meanwhile, China and India, responsible for roughly one-third of global greenhouse gas emissions in 2019, miss the deadline. An IPCC report [PDF] released the following month predicts that the world will reach or exceed 1.5°C of warming within the next two decades even if nations drastically cut emissions immediately.

2021 –  1.5°C goal maintained at COP26 in Glasgow

COP26 President Alok Sharma says commitments made during the conference keep the Paris Agreement’s goal of limiting warming to 1.5°C “alive” but its “pulse is weak.” The final agreement, the Glasgow Climate Pact, calls for countries to reduce coal use and fossil fuel subsidies—both firsts for a UN climate agreement—and urges governments to submit more ambitious emissions-reduction targets by the end of 2022. In addition, delegates finally establish rules for a global carbon market. Smaller groups of countries make notable side deals on deforestation, methane emissions, coal, and more. But analysts note that even if countries follow through on their pledges for 2030 and beyond, the world’s average temperature will still rise 2.1°C (3.8°F).

2022 – Breakthrough on Loss and Damage at COP27 in Sharm el-Sheikh

At COP27 in Sharm el-Sheikh, nations agree [PDF] for the first time to establish a fund to compensate poor and vulnerable countries for losses and damages due to climate change, though the details are left undecided. Also for the first time, the conference’s final communiqué calls for global financial institutions to revamp their practices to address the climate crisis. However, countries don’t commit to phasing down use of all fossil fuels, and a goal to reach peak emissions by 2025 is removed from the communiqué. Guterres says that continuing to use fossil fuels means “double trouble” for the planet.
