UNFCCC and the Conference of the Parties (COP)

The United Nations Framework Convention on Climate Change (UNFCCC) is the main world treaty on climate change. It was agreed in 1992, and almost every country has joined it. The Conference of the Parties (COP) is the yearly meeting of all the countries that have joined, called "Parties". It is the treaty's highest decision-making body, so when the news says "COP31", it means the 31st such yearly meeting.

Why does it exist?

Climate change is a shared problem. Carbon dioxide released in one country warms the whole planet. No single country can fix it alone, and no country wants to cut emissions if others do not. So countries need one common table where they can agree on rules, share information and check each other's progress. The UNFCCC gives that table, and the COP is where they sit down every year.

Where did it come from?

Scientists raised the alarm about global warming in the 1980s. The Intergovernmental Panel on Climate Change (IPCC) was set up in 1988 to assess the science. The UNFCCC was then opened for signature at the Earth Summit in Rio de Janeiro in June 1992. It came into force on 21 March 1994. The first COP (COP1) was held in Berlin in 1995. Since then, COPs have met every year, except in 2020 when the COVID-19 pandemic postponed COP26 to 2021.

What does the treaty say?

The main aim is written in Article 2: to keep greenhouse gases in the air at a level that prevents "dangerous" human interference with the climate. The treaty is a framework. That means it sets goals and principles but not hard, country-wise emission cuts. Those came later through two add-on agreements:

• Kyoto Protocol (1997, in force 2005): gave legally binding emission cuts only to rich (developed) countries.
• Paris Agreement (2015, in force 2016): every country sets its own targets, called Nationally Determined Contributions (NDCs), and updates them every five years.

How does the treaty group countries?

The UNFCCC puts countries in lists called "Annexes":

• Annex I: industrialised countries and "economies in transition" (like Russia and East European countries). They were expected to lead in cutting emissions.
• Annex II: a smaller group of richer Annex I countries that must also give money and technology to developing countries.
• Non-Annex I: mostly developing countries, including India and China.

Türkiye is an interesting case. It was listed in both Annex I and Annex II in 1992. At COP7 in Marrakesh in 2001, it was removed from Annex II, but it stayed in Annex I. It ratified the Paris Agreement only in October 2021.

Who runs a COP?

Many bodies work together:

• COP President: usually a minister from the host country. The President chairs the meeting and guides the talks towards a final deal.
• COP Bureau: 11 officers: the President, seven Vice-Presidents, the chairs of the two subsidiary bodies, and a Rapporteur (the person who records the meeting's report).
• Subsidiary bodies: the SBSTA (Subsidiary Body for Scientific and Technological Advice) and the SBI (Subsidiary Body for Implementation). They meet twice a year: once in June in Bonn, and again during the COP. The June meeting prepares the ground for the COP.
• UNFCCC Secretariat: the permanent office that organises everything. It is based in Bonn, Germany, since 1996.

Three meetings under one roof

A "COP" today is really three meetings held at the same time:

• COP: the meeting of Parties to the UNFCCC itself.
• CMP: the meeting of Parties to the Kyoto Protocol.
• CMA: the meeting of Parties to the Paris Agreement.

So COP31 in 2026 is also CMP21 and CMA8. Each keeps its own decisions, even though they share the same venue and dates.

How are hosts chosen?

The COP presidency rotates among the five UN regional groups: Africa, Asia-Pacific, Latin America and the Caribbean, Central and Eastern Europe, and the Western European and Others Group (WEOG). The group whose turn it is must agree, among itself, on one host. If the group cannot agree, the conference goes to Bonn, the seat of the Secretariat, by default. There is no voting rule to break such a deadlock. One side must step back.

How are decisions made?

Here is a key fact for exams. The COP has never formally adopted its own rules of procedure. The draft rules were written in 1996, but countries could not agree on draft Rule 42, the voting rule. One option allowed a two-thirds majority vote if consensus failed; the other allowed only consensus. So since COP1, the COP applies the draft rules except Rule 42, and decides everything by consensus.

Consensus means no country formally objects. It is not the same as everyone voting "yes". In practice, this gives even one determined group of countries the power to block or weaken a text.

India's position and Indian examples

India signed the UNFCCC on 10 June 1992 and ratified it on 1 November 1993. India hosted COP8 in New Delhi in 2002, which adopted the Delhi Ministerial Declaration. That declaration stressed technology transfer to developing countries and the need to help them cope with climate impacts. India has consistently argued for equity and for the principle of common but differentiated responsibilities: rich countries should act first and pay more because they polluted first. India offered to host COP33 in 2028, but withdrew that offer in April 2026.

Commonly confused concepts

• UNFCCC vs IPCC: The UNFCCC is a treaty where governments negotiate. The IPCC is a scientific body that assesses research and writes reports. The IPCC does not make rules.
• COP vs CMA vs CMP: COP is for the UNFCCC. CMA is for the Paris Agreement. CMP is for the Kyoto Protocol.
• UNFCCC COP vs other COPs: The word "COP" is used by many treaties. The Convention on Biological Diversity (CBD) and the UN Convention to Combat Desertification (UNCCD) also hold COPs. Together, the UNFCCC, CBD and UNCCD are called the three Rio Conventions, all linked to the 1992 Earth Summit.
• COP vs SB (Bonn) sessions: The June Bonn meetings are technical, working-level sessions. Final decisions are adopted only at the COP.
• COP President vs UNFCCC Executive Secretary: The President is a host-country minister for one year. The Executive Secretary heads the permanent Secretariat.

Issues, criticism and the way forward

• Consensus can mean the weakest deal. Because any group can block a text, strong words (for example, on fossil fuels) often get diluted or dropped. Some experts suggest voting as a last resort. Others warn that voting could push countries to leave the process.
• Host-country credibility. Several recent hosts are big fossil fuel producers or users. Critics say this creates a conflict of interest. Supporters say bringing producers inside the talks is the only way to change them.
• Hosting deadlocks. The rotation system has no tie-breaker, as the long fight over COP31 showed.
• Implementation gap. Many promises made at COPs are voluntary pledges outside the formal decisions, and follow-up is weak.
• Climate finance. Developing countries say rich countries have not delivered enough money. Rich countries want large emerging economies to contribute too.
• Way forward: Suggestions include clearer rules for hosts, stronger review of pledges, and better use of the five-yearly Global Stocktake to push countries to do more.

Concepts to Know

• Greenhouse gases: Gases such as carbon dioxide and methane that trap the Sun's heat near the Earth, like a blanket. More of them means a warmer planet.
• Ratify: When a country formally confirms, through its own legal process, that it will be bound by a treaty it has signed. Signing alone is a promise to consider; ratifying is the real commitment.
• Framework convention: A treaty that sets broad goals and a system for talks, leaving detailed rules for later agreements (called protocols).
• Rapporteur: The official who writes down and presents the report of a meeting.
• UN regional groups: Five groups of countries used by the UN to share out posts and hosting turns fairly across the world.
