Common But Differentiated Responsibilities (CBDR) is a principle that was formalized in the United Nations Framework Convention on Climate Change (UNFCCC) of Earth Summit in Rio de Janeiro, 1992. The CBDR principle is mentioned in UNFCCC article 3 paragraph 1.., [1] and article 4 paragraph 1. [2] It was the first international legal instrument to address climate change and the most comprehensive international attempt to address negative impacts to global environment. [3] The CBDR principle acknowledges that all states have shared obligation to address environmental destruction but denies equal responsibility of all states with regard to environmental protection.
In the Earth Summit, states acknowledged disparity of economic development between developed and developing countries. Industrialization proceeded in developed countries much earlier than it did in developing countries. CBDR is based on the relationship between industrialization and climate change. [4] The more industrialized a country is, the more likely that it has contributed to climate change. States came to an agreement that developed countries contributed more to environmental degradation and should have greater responsibility for climate change mitigation than developing countries should. The CBDR principle could therefore be said to be based on the polluter-pays principle where historical contribution to climate change and respective ability to combat climate change become measures of responsibility for environmental protection. [5]
The concept of CBDR evolved from the notion of "common concern" in Convention for the Establishment of an Inter-American Tropical Tuna Commission of 1949 [6] and "common heritage of mankind" in United Nations Convention on the Law of the Sea, 1982. [7]
In general, there are three objectives of contracting differential treatment; to bring substantive equality in a framework for justice, to foster cooperation among states, and to provide incentives for states to implement their obligations. [8]
In the Earth Summit, the CBDR principle was established to apprise the world that pollution transcends political boundaries and that environmental protection should be achieved through means of cooperation. UNFCCC 1992, Article 3 paragraph 1, "The Parties should protect the climate system for the benefit of present and future generations of humankind, on the basis of equity and in accordance with their common but differentiated responsibilities and respective capabilities. Accordingly, the developed country Parties should take the lead in combating climate change and the adverse effects thereof." [1]
CBDR was not the first differential treatment of countries in international agreements. There were other protocols and agreements that employed a principle of differential treatment:

Todd Stern, then U.S. Special Envoy on Climate Change, said in his commencement speech at Dartmouth's 2012 graduation ceremony that the world can no longer have two distinct categories of countries having different responsibility for climate change mitigation. Countries should instead follow differentiation of a continuum, where states are required to act vigorously according to their own circumstances, abilities and responsibilities. He emphasized sharing the responsibility to reduce carbon emissions between all countries instead of having a group of countries take the bulk of the responsibility for mitigation.
Stone argues that the meaning of the word 'differentiated' could be problematic as every agreement differentiates. [11] He also says CBDR is "neither universal nor self-evident." [12]
Cullet points out that with CBDR, it may be difficult to determine the existence of specific customary norms. [13]
In 2002, Lavanya Rajamani argued that developing countries would have an unfair economic advantage because they would not face the same restrictions as would developed counties. A climate change treaty would be ineffective without the participation of developing countries. The US has suggested that developing countries are not doing enough to satisfy their share of 'common responsibility for the problem' of climate change. Developing countries, however, argued that their carbon emissions are essential to their survival, while those of the developed countries are 'luxury emissions.' [14]
The Paris Agreement departed from the prior paradigm of rigid categorization between industrialized and developing countries. Under prior agreements, such as the Kyoto Protocol, there was a rigid distinction between Annex 1 and Annex 2 countries among the parties to the Kyoto Protocol, which determined the countries' responsibilities. Industrialized (Annex 1) countries had to observe strict limits on emissions, while other countries did not. Under the Paris Agreement, each country makes its own nationally determined contribution based on its own national circumstances, and as circumstances change, so do the responsibilities. [15]
The Kyoto Protocol (Japanese: 京都議定書, Hepburn: Kyōto Giteisho) was an international treaty which extended the 1992 United Nations Framework Convention on Climate Change (UNFCCC) that commits state parties to reduce greenhouse gas emissions, based on the scientific consensus that global warming is occurring and that human-made CO2 emissions are driving it. The Kyoto Protocol was adopted in Kyoto, Japan, on 11 December 1997 and entered into force on 16 February 2005. There were 192 parties (Canada withdrew from the protocol, effective December 2012) to the Protocol in 2020.
The United Nations Framework Convention on Climate Change (UNFCCC) is the UN process for negotiating an agreement to limit dangerous climate change. It is an international treaty among countries to combat "dangerous human interference with the climate system". The main way to do this is limiting the increase in greenhouse gases in the atmosphere. It was signed in 1992 by 154 states at the United Nations Conference on Environment and Development (UNCED), informally known as the Earth Summit, held in Rio de Janeiro. The treaty entered into force on 21 March 1994. "UNFCCC" is also the name of the Secretariat charged with supporting the operation of the convention, with offices on the UN Campus in Bonn, Germany.
The United Nations Conference on Environment and Development (UNCED), also known as the RioConference or the Earth Summit, was a major United Nations conference held in Rio de Janeiro from 3 to 14 June 1992.
Post-Kyoto negotiations refers to high level talks attempting to address global warming by limiting greenhouse gas emissions. Generally part of the United Nations Framework Convention on Climate Change (UNFCCC), these talks concern the period after the first "commitment period" of the Kyoto Protocol, which expired at the end of 2012. Negotiations have been mandated by the adoption of the Bali Road Map and Decision 1/CP.13.
The World Ocean Conference 2009 (WOC) was an international conference to develop a common understanding and firm commitment to address the adverse impact of climate change on the state of the world's oceans, and increase understanding on the role of the oceans as ‘climate moderator’. This conference includes diplomats and heads of state from a number of countries. It took place in May 2009 in Manado, Indonesia. Its topic is the threat to various nations from rising oceans due to global warming.
Environmental governance (EG) consists of a system of laws, norms, rules, policies and practices that dictate how the board members of an environment related regulatory body should manage and oversee the affairs of any environment related regulatory body which is responsible for ensuring sustainability (sustainable development) and manage all human activities—political, social and economic. Environmental governance includes government, business and civil society, and emphasizes whole system management. To capture this diverse range of elements, environmental governance often employs alternative systems of governance, for example watershed-based management. Obviously, in fact the EG arrangements are very diversed and not at all as inclusive as we could wish them to be.
Climate debt is the debt said to be owed to developing countries by developed countries for the damage caused by their disproportionately large contributions to climate change. Historical global greenhouse gas emissions, largely by developed countries, pose significant threats to developing countries, who are less able to deal with climate change's negative effects. Therefore, some consider developed countries to owe a debt to developing ones for their disproportionate contributions to climate change.
In political ecology and environmental policy, climate governance is the diplomacy, mechanisms and response measures "aimed at steering social systems towards preventing, mitigating or adapting to the risks posed by climate change". A definitive interpretation is complicated by the wide range of political and social science traditions that are engaged in conceiving and analysing climate governance at different levels and across different arenas. In academia, climate governance has become the concern of geographers, anthropologists, economists and business studies scholars.
The BASIC countries are a bloc of four large newly industrialized countries – Brazil, South Africa, India and China – formed by an agreement on 28 November 2009. The four committed to act jointly at the Copenhagen climate summit, including a possible united walk-out if their common minimum position was not met by the developed nations. All are members of BRICS, which also includes Russia and other developing countries that joined the bloc in 2024.
The Kyoto Protocol was an international treaty which extended the 1992 United Nations Framework Convention on Climate Change.
Nationally Appropriate Mitigation Action (NAMA) refers to a set of policies and actions that countries undertake as part of a commitment to reduce greenhouse gas emissions. The term recognizes that different countries may take different nationally appropriate action on the basis of equity and in accordance with common but differentiated responsibilities and respective capabilities. It also emphasizes financial assistance from developed countries to developing countries to reduce emissions.
The Paris Agreement is an international treaty on climate change that was adopted in 2015. The treaty covers climate change mitigation, adaptation, and finance. The Paris Agreement was negotiated by 196 parties at the 2015 United Nations Climate Change Conference near Paris, France. As of February 2023, 195 members of the United Nations Framework Convention on Climate Change (UNFCCC) are parties to the agreement. Of the three UNFCCC member states which have not ratified the agreement, the only major emitter is Iran. The United States withdrew from the agreement in 2020, but rejoined in 2021.
The 2011 United Nations Climate Change Conference (COP17) was held in Durban, South Africa, from 28 November to 11 December 2011 to establish a new treaty to limit carbon emissions.
The 2012 United Nations Climate Change Conference was the 18th yearly session of the Conference of the Parties (COP) to the 1992 United Nations Framework Convention on Climate Change (UNFCCC) and the 8th session of the Meeting of the Parties (CMP) to the 1997 Kyoto Protocol. The conference took place from Monday 26 November to Saturday 8 December 2012, at the Qatar National Convention Centre in Doha.
The United Nations Climate Change Conferences are yearly conferences held in the framework of the United Nations Framework Convention on Climate Change (UNFCCC). They serve as the formal meeting of the UNFCCC parties – the Conference 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. Starting in 2005 the conferences have also served as the "Conference of the Parties Serving as the Meeting of Parties to the Kyoto Protocol" (CMP); also parties to the convention that are not parties to the protocol can participate in protocol-related meetings as observers. From 2011 to 2015 the meetings were used to negotiate the Paris Agreement as part of the Durban platform, which created a general path towards climate action. Any final text of a COP must be agreed by consensus.
The 2016 United Nations Climate Change Conference was an international meeting of political leaders and activists to discuss environmental issues. It was held in Marrakech, Morocco, on 7–18 November 2016. The conference incorporated the twenty-second Conference of the Parties (COP22), the twelfth meeting of the parties to the Kyoto Protocol (CMP12), and the first meeting of the parties to the Paris Agreement (CMA1). The purpose of the conference was to discuss and implement plans about combatting climate change and to "[demonstrate] to the world that the implementation of the Paris Agreement is underway". Participants work together to come up with global solutions to climate change.
Action for Climate Empowerment (ACE) is a term adopted by the United Nations Framework Convention on Climate Change (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. The importance of ACE is reflected in other international frameworks such as the Sustainable Development Goals ; the Global Action Programme for Education for Sustainable Development ; the Aarhus Convention (2011); the Escazú Agreement (2018) and the Bali Guidelines (2010).
There are various theoretical frameworks to mitigate climate change. Frameworks are significant in that they provide a lens through which an argument can be addressed, and can be used to understand the possible angles from which to approach solving climate change. Frameworks in political science are used to think about a topic from various angles in order to understand different perspectives of the topic; common ones in international political science include rationalist, culturalist, marxist, and liberal institutionalist. See international relations theory for more frameworks through which problems can be analyzed.
