On the globe, you will find one and only international organisation which promotes peace, security, social progress, better living standards and human rights. Can you guess the name of that organisation? Yes, you are correct, that is the United Nations. The United Nations is an international organization founded with 51 membership countries in 1945, having headquarters at New York, USA, now increased to 193 Member States. The UN is playing a key role in international environmental issues and climate change.
We know that the changes in Earth’s climate is a fallout of global warming which has happened due to a few natural causes in general but a lot of anthropogenic activities in particular. Release of toxic greenhouse gases (GHGs) to the atmosphere from industrial and vehicular emissions and aerosols could trap the outgoing heat and raise air temperatures near the ground leading to global warming. You have understood about GHGs and global warming elaborately in the previous unit.
The Intergovernmental Panel on Climate Change (IPCC) of the UN has warned that the increasing levels of global warming are mostly due to human activities of the past five decades. The world is now experiencing the effects of global warming in the form of rising sea levels, decrease in snow cover, moving ice sheets, changing rainfall patterns, and occurrence of extreme weather events in many areas across the globe.
The UN opines that the GHG emissions must be reduced to prevent global warming and arrest the climate change impact on the environment. Do you think this is possible only with one country or a region? No, it must be the cumulative efforts of all the nations of the planet Earth. Reducing emissions of GHGs depends on the actions of various countries of the world, but it is not in the hands of a particular region or country.
The World Meteorological Organization (WMO), the United Nations Environment Programme (UNEP), and the International Council of Scientific Unions (ICSU) started the World Climate Programme to tackle climate change problems in 1979. This was slowly led to the formation of IPCC in 1988 to assess the magnitude and timing of changes, estimate their impacts, and evaluate management strategies. You will understand how the United Nations Framework Convention on Climate Change (UNFCCC) came into existence and is playing a significant role in addressing the above problems.
Let us first understand the objective and principles of UNFCCC and how it is really a matter of global concern. Initially, a total of 154 States Members of the world met in 1992, at the UN Earth Summit in Rio de Janeiro, Brazil, and signed this Convention. The countries ratified the Convention and agreed upon reducing their greenhouse gas emissions.
The main objective of the Convention is to “stabilize greenhouse gas concentrations at a level that would prevent dangerous anthropogenic interference with the climate system.” Keeping in consideration of the food production and economic development in a sustainable manner, such a level should be achieved within a time-line. The ecosystems must be allowed to adapt naturally to climate change. It may be essential to think of the bearable limits of emissions by the atmosphere. This framework convention is a legally binding treaty aimed at lowering the emissions of carbon dioxide (CO2) and other greenhouse gases.
You will be astonished to know that once CO2 is emitted, it stays nearly 100 years and more time in the climate system. The treaty was expected to come into operation immediately. The developed countries should lead, and the developing countries should be compensated for costs incurred for taking necessary measures for controlling climatic change. Governments should submit reports on their activities and meet regularly to review progress.
To do this more effectively, the UNFCCC had adopted some principles. These important principles of the Convention are made to protect the climate system for the benefit of present and future generations of mankind (UNFCCC Handbook, 2006).
We now study briefly the working administration of UNFCCC. The Convention has established several institutions to work within the framework. These are the Conference of the Parties to the Convention (COP), the subsidiary bodies (SBs), the Bureau and the Secretariat.
COP is the “supreme body” of the Convention and is responsible for reviewing and making decisions necessary to promote the effective implementation of the Convention.
Subsidiary bodies—namely the Subsidiary Body for Scientific and Technological Advice (SBSTA) and the Subsidiary Body for Implementation (SBI)—are designated as advisory bodies to the COP. Each have a Bureau which consists of a Chair, a Vice-Chair and a Rapporteur. These SBs conduct the sessions on climate change processes and recommend draft decisions to the COP for taking final decisions.
We now discuss some of the important conventions held after the Rio Earth Summit to know the initiatives taken to address the issues of climate change. Table provided below explains broadly about the details of the Convention.

Enhanced the time period for Lima work programme on gender and its gender action plan to achieve and sustain the full, equal and meaningful participation of women in the UNFCCC process. |
Under the Kyoto Protocol, the Parties are legally bound by specific commitments on GHG reduction. In December 1997, COP 3 held at Kyoto, Japan, adopted the Protocol unanimously, and it came into force on 16th February 2005. The industrialized countries agreed to reduce greenhouse gas emissions to an average of 5.2% below the 1990 levels during the five-year commitment period from 2008 to 2012.
Key issues addressed by the Kyoto Protocol include:
The Protocol also provides for a comprehensive inclusion of GHGs and sources. A basket of four important gases and two groups of gases are addressed under the Kyoto Protocol:
Additionally, the Protocol introduced flexibility mechanisms such as land use changes and forest activities (e.g., afforestation, reforestation, and deforestation), allowing countries to meet a portion of their commitments by earning credits for GHG emissions avoided or removed in other countries. It also allowed grouping of Parties, such as the European Union, to be considered jointly for emission counting.
The Kyoto Protocol of 1997 marked the beginning of global cooperation on climate change. It aimed to fulfill the commitments made in 1992 during the UN Earth Summit, focusing on stabilizing GHGs to prevent dangerous interference with the climate system.
However, two major issues emerged:
The Protocol required ratification by countries representing 55% of CO2 emissions in the developed world. It took seven years post-signing to enact. Australia ratified in 2008, Kazakhstan in 2009. The United States, responsible for ~25% of global emissions despite less than 5% of the global population, did not ratify the Protocol.
Progress was unsatisfactory:
Some progress was made by countries like:
Developing countries faced a dilemma: while most vulnerable to climate change, they are urged to restrict economic growth to reduce emissions.
At the UN Climate Summit in Copenhagen, December 2009, a non-binding accord drafted by the US, China, Brazil, India, and South Africa aimed to cap temperature rise at 2°C above pre-industrial levels, but lacked concrete implementation strategies.
Climate change not only affects human development but also significantly impacts plant and animal species. It can lead to habitat shifts, changes in species life cycles, and in extreme cases, extinction. Rising temperatures and low rainfall contribute to drylands turning into deserts. The Rio Conventions—UNFCCC, UNCCD, and UNCBD—collaborate on climate adaptation, desertification control, biodiversity conservation, and sustainable development.
Initiated by the United Nations Environment Programme (UNEP) in 1987, the foundation for an internationally binding agreement on biodiversity was laid. On 5th June 1992, the United Nations Convention on Biological Diversity (UNCBD) was opened for signature during the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro. It came into force on 29 December 1993, and now has a membership of 188 countries.
The CBD is a legally binding treaty with three main objectives:
The principle emphasizes that States have the sovereign right to exploit their own resources under their environmental policies, while also bearing the responsibility to prevent environmental harm beyond national borders (CBD Handbook, 2005).
Parties are expected to design and report activities supporting climate adaptation based on national and local needs.
The UNCBD operates through three core institutions:
These bodies oversee measures such as in situ and ex situ conservation, research and training, public awareness, impact assessments, access to genetic resources, technology transfer, and financial resource allocation.
Two important protocols under the Convention are described below:
Adopted on 29 January 2000 in Montreal, Canada, the Cartagena Protocol on Biosafety governs the movement of living modified organisms (LMOs) across borders.
Its goal is to ensure safe handling and use of LMOs that may affect biodiversity and human health, especially in the context of trans-boundary movement (CBD Handbook, 2005).
Adopted on 29 October 2010 in Nagoya, Japan, the Nagoya Protocol focuses on access to genetic resources and the fair and equitable sharing of benefits from their use.
Key benefits of this Protocol include:
Food and Agriculture Organization (FAO) and the Global Plan of Action for the Conservation and Sustainable Utilization of Plant Genetic Resources contributed significantly under the Convention. FAO defines agro-biodiversity as “The variety and variability of animals, plants and micro-organisms that are used directly or indirectly for food and agriculture...”
According to the FAO, 90% of our food, energy, and protein today comes from only 15 plants and 8 animal species, with wheat, rice, and maize providing over 50% of the global plant-based energy intake.
This theme is a joint initiative by the Convention on Biological Diversity and the Convention to Combat Desertification.
Dry and sub-humid lands include arid/semi-arid regions, grasslands, savannahs, and Mediterranean landscapes. Their biodiversity is highly adapted to harsh environments.
In 2006, the UN declared the International Year for Deserts and Desertification to highlight its role in poverty eradication and sustainable development.
Infant mortality in these regions stands at 54 per 1,000 live births, twice the rate of temperate areas, underlining the development urgency.
This biodiversity supports the livelihood of millions and contributes to global food production.
Forest biodiversity includes all life forms and their interactive roles within forested areas. This includes trees, plants, animals, and microorganisms along with their genetic diversity.
“Forest biological diversity results from evolutionary processes driven by ecological forces such as climate, fire, and competition over thousands or millions of years.”
FAO estimates that we lose nearly 13 million hectares of forest annually due to deforestation, fragmentation, and degradation.
Inland waters include lakes, rivers, ponds, streams, springs, groundwater, bogs, marshes, and swamps—fresh, saline, or brackish.
The Ramsar Convention defines wetlands as "areas of marsh, fen, peatland, or water... where water is static or flowing, fresh, brackish, or salty."
Islands are land masses surrounded by water, ranging in size from 0.15 km² to 2.2 million km² (Greenland). Their isolation fosters specialized species with adaptations like gigantism, dwarfism, flightlessness, and loss of dispersal traits.
Islands hold evolutionary significance and act as reservoirs of genetic diversity.
The majority of Earth's surface is occupied by oceans, which harbour 95% of the biosphere. Marine and coastal biodiversity includes coral reefs, mangroves, seagrass meadows, estuaries, seamounts, and soft/rocky bottoms.
Millions of people depend on marine fish and invertebrates for their food sources.
The UNEP-World Conservation Monitoring Centre and UNEP’s Mountain Programme have developed a systematic assessment of mountain ecosystems, utilizing Geographic Information System (GIS) analysis of global data.
Nearly 27% of the world's land surface is occupied by mountains, providing fresh water to numerous species, including humans.
At the Rio Earth Summit, State Members of the world negotiated and announced the Non-legally Binding Authoritative Statement of Principles for a Global Consensus on the Management, Conservation, and Sustainable Development of all Types of Forests. These principles are commonly referred to as the “Forest Principles”.
The main purpose of these principles is to strengthen political commitment and action at national and international levels for the effective implementation of sustainable forest management.
You can learn more about forestry by visiting the website: FAO Forestry and explore the references section for additional links.
The United Nations emphasizes that the Forest Principles will help maintain and enhance the economic, social, and environmental values of all types of forests, benefiting present and future generations.
During the Rio Earth Summit, several State Parties raised a confrontation on various environmental issues, particularly regarding the emission of greenhouse gases (GHGs), global warming, and ozone depletion. A major conflict emerged between developed and developing countries regarding responsibility for environmental damage and who should pay for its repair.
The UNFCCC stated that developed nations (referred to as the 'North') are primarily responsible for producing nearly 70% of total GHG emissions, and thus, they must lead efforts to reduce emissions, as argued by the 'South'.
In the global North, countries like Australia and New Zealand were included, while China was included in the global South.
