UPSC — Environment

The UNFCCC is the foundational multilateral environmental agreement on climate change. Its ultimate objective (Article 2) is to achieve stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system — within a time-frame that allows ecosystems to adapt naturally, ensures food production is not threatened, and enables sustainable economic development.

• CBDR-RC: common but differentiated responsibilities and respective capabilities — the philosophical spine of North–South climate politics.
• Annex I: industrialised countries + economies in transition — historically expected to take the lead on mitigation.
• Annex II: a subset of Annex I with additional obligations to provide financial resources and facilitate technology transfer to developing countries.
• Non-Annex I: mostly developing countries, including India.
• Institutional engine: COP (supreme body), SBI (Implementation), SBSTA (Scientific and Technological Advice), Bureau, and the secretariat in Bonn.

Publish inventories and national communications / biennial reports (formats evolved over time), formulate programmes containing measures to mitigate climate change and facilitate adaptation, promote science and education, and cooperate on finance and technology. The Convention itself did not lock every country into Kyoto-style numerical caps; that came later via the Protocol and then Paris.

India has consistently argued equity, per-capita emissions, historical responsibility, and the right to development. Domestic planning bridges include the National Action Plan on Climate Change (NAPCC) with its missions, State Action Plans, and the evolving Long-Term Low Emission Development Strategy submitted in the Paris era.

Kyoto operationalised the Convention for a first generation of binding targets. Annex I Parties accepted quantified emission limitation and reduction objectives for listed greenhouse gases over commitment periods. The first commitment period ran 2008–2012. The Doha Amendment created a second commitment period (2013–2020); its politics and ratification story are less central now than Paris, but the architecture still appears in Prelims comparisons.

• Clean Development Mechanism (CDM): Annex I Party earns certified emission reductions (CERs) from projects in non-Annex I countries — sustainable development + cost-effective compliance narrative. India was a major CDM host.
• Joint Implementation (JI): among Annex I Parties (often involving economies in transition).
• International Emissions Trading: trading of assigned amount units among Annex I Parties.

क्योटो लचीले तंत्र — “सीधा जा ईटी”: CDM, JI, Emissions Trading।

Kyoto’s hard split left large emerging emitters without QELROs and some major emitters outside the regime at key moments. Paris shifted to universal participation with nationally determined pledges, while keeping differentiation language softer and more flexible.

Paris is a legally binding agreement (as a treaty instrument) that combines binding process obligations with nationally determined substance. It aims to strengthen the global response by holding temperature increase to well below 2°C and pursuing 1.5°C, increasing adaptation ability, and making finance flows consistent with low-emission climate-resilient development.

• NDCs: each Party’s self-defined contribution; communicated every five years; expected to represent a progression.
• Global Stocktake: collective progress check every five years; first GST at COP28 informs the next round of NDCs.
• Enhanced Transparency Framework: reporting and review so pledges can be tracked without Kyoto’s Annex-I-only compliance psychology.
• Article 6: voluntary cooperation — market and non-market — with rules against double counting.
• Adaptation & loss and damage: Paris recognises the importance of averting, minimising and addressing loss and damage (Article 8); the dedicated Fund was a later COP political breakthrough.

• Emissions intensity of GDP: −45% by 2030 vs 2005.
• ~50% cumulative installed electric power capacity from non-fossil resources by 2030.
• Additional carbon sink of 2.5–3 GtCO₂e through additional forest & tree cover by 2030.
• Long-term political goal: net-zero by 2070 (COP26).

पेरिस लय: “पाँच साल NDC, पाँच साल Stocktake” — पहला GST = COP28 दुबई।

The Intergovernmental Panel on Climate Change assesses the science related to climate change. It does not conduct new primary research in the way a lab does; it assesses and synthesises peer-reviewed literature. It does not prescribe policy, though policymakers use its reports intensively.

• WG I: physical science basis.
• WG II: impacts, adaptation, vulnerability.
• WG III: mitigation of climate change.
• TFI (Task Force on National Greenhouse Gas Inventories): inventory methodologies used by countries.

IPCC ग्रुप्स — “विज्ञान–असर–रोकथाम”: WG1 science, WG2 impacts/adaptation, WG3 mitigation। याद रखो — IPCC संधि नहीं।

Landmark products often in CA: AR5, AR6, Special Report on 1.5°C (SR1.5), SRCCL (land), SROCC (ocean & cryosphere). Exam trap: confusing IPCC with UNFCCC secretariat or with a funding body.

The CBD is the main global treaty for biodiversity. It has three equally important objectives: (1) conservation of biological diversity; (2) sustainable use of its components; and (3) fair and equitable sharing of benefits arising out of the utilisation of genetic resources. Sovereignty of States over their natural resources is recognised, alongside a duty not to cause damage to the environment of other States or areas beyond national jurisdiction.

CBD के तीन लक्ष्य — “बचाओ–बरतो–बाँटो”: Conservation, Sustainable use, Benefit sharing (ABS)।

• COP is the governing body; SBSTTA provides scientific advice.
• National Biodiversity Strategies and Action Plans (NBSAPs) are the principal domestic planning instruments.
• Aichi Biodiversity Targets (2011–2020) were the previous decade’s framework; most were not fully achieved globally.
• Kunming–Montreal Global Biodiversity Framework (GBF) adopted at CBD COP15 (2022): includes the headline “30×30” style targets (protect at least 30% of terrestrial and inland water areas and of marine/coastal areas by 2030 — verify exact target text when revising), plus targets on restoration, pollution, subsidies, ABS, and finance.

Biological Diversity Act, 2002; National Biodiversity Authority (Chennai); State Biodiversity Boards; Biodiversity Management Committees; people’s biodiversity registers. ABS Regulations operationalise Nagoya-aligned access rules. Questions often ask which body grants approval for access to biological resources / associated knowledge.

Cartagena addresses the safe transfer, handling and use of Living Modified Organisms (LMOs) resulting from modern biotechnology that may have adverse effects on biodiversity, also taking risks to human health into account. It is especially about transboundary movement.

• Advance Informed Agreement (AIA): procedure ensuring the importing Party is informed and consents before the first intentional transboundary movement of an LMO for intentional introduction into the environment.
• Biosafety Clearing-House (BCH): information exchange mechanism.
• Risk assessment / risk management obligations; documentation for shipments.
• Nagoya–Kuala Lumpur Supplementary Protocol (on Liability and Redress) is a related later instrument — know the name even if details are secondary.

कार्टाजेना = “कार्गो LMO सुरक्षित लाओ” (Biosafety / AIA)। नागोया = “नफा बाँटो” (Access + Benefit Sharing)।

Nagoya implements the CBD’s third objective. It sets rules for access to genetic resources and for the fair and equitable sharing of benefits arising from their utilisation, including from associated traditional knowledge where applicable.

• Prior Informed Consent (PIC) of the provider country (and relevant indigenous/local communities where domestic law so requires).
• Mutually Agreed Terms (MAT) — contract-like terms on benefit sharing (monetary and non-monetary).
• Compliance measures in user countries; checkpoints; internationally recognised certificates of compliance via the ABS Clearing-House.
• Covers utilisation of genetic resources (R&D on genetic/biochemical composition) — biotechnology and pharma narratives dominate examples.

नागोया चाबी — “पहले इजाज़त (PIC), फिर शर्तें (MAT), फिर लाभ बाँटो”। भारत में NBA / BD Act 2002 से जोड़ो।

India’s Biological Diversity Act regime (National Biodiversity Authority approvals, benefit-sharing arrangements) is the classic domestic linkage in UPSC questions.

CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) regulates international trade in specimens of wild animals and plants to ensure trade does not threaten survival. It is not a habitat-protection convention like CBD/Ramsar; its lever is permits and listings.

• Appendix I: species threatened with extinction. Commercial international trade is generally prohibited; limited non-commercial trade may be allowed with strict permits from both exporting and importing countries.
• Appendix II: species not necessarily threatened with extinction now, but trade must be controlled to avoid utilisation incompatible with survival. Trade allowed with export permits (and other checks) if not detrimental to survival.
• Appendix III: species protected in at least one country that has asked others for assistance in controlling trade. Listing can be done by a Party for its own species with a different procedure from App I/II CoP votes.

CITES अपेंडिक्स — “एक बंद, दो कंट्रोल, तीन मदद माँगो”: I = व्यापार लगभग बंद, II = नियंत्रित व्यापार, III = एक देश ने मदद माँगी।

Conference of the Parties amends Appendices; Animals Committee and Plants Committee provide technical advice; Standing Committee oversees between CoPs. In India, CITES implementation intertwines with the Wildlife (Protection) Act, customs controls, and designated Management/Scientific Authorities. Recent CoPs often put sharks, rays, timber trees, and exotic pets into the news — perfect CA fodder.

CMS conserves migratory species that periodically cross one or more national jurisdictional boundaries. “Range States” are countries that exercise jurisdiction over any part of the range of a migratory species.

• Appendix I: endangered migratory species — Parties prohibit taking except in tightly limited circumstances.
• Appendix II: species that have an unfavourable conservation status and need or would significantly benefit from international cooperation — basis for Agreements and MoUs.
• CMS family includes legally binding Agreements and lighter MoUs (e.g. on raptors, dugong, sharks, Siberian crane — India-linked examples appear frequently in coaching lists; confirm the latest MoU set before quoting).

CMS = “घुमंतू प्रजाति बॉन में” — Appendix I = खतरे में (taking बंद), II = सहयोग/MoU चाहिए।

India has also used CMS COP hosting/diplomacy in recent years as a current-affairs hook — pair the instrument with whatever latest COP host/outcome is in the news when you revise.

The IUCN Red List is the global standard for assessing extinction risk. Categories from most to least severe among threatened/extinct classes commonly tested: Extinct (EX), Extinct in the Wild (EW), Critically Endangered (CR), Endangered (EN), Vulnerable (VU), then Near Threatened (NT), Least Concern (LC), plus Data Deficient (DD) and Not Evaluated (NE).

CR + EN + VU together are the “threatened” categories. A Red List assessment informs CITES debates, national wildlife schedules, and protected-area priorities, but an IUCN listing by itself is not an international trade ban — that is CITES / domestic law.

IUCN रेड लिस्ट सीढ़ी — “बिलकुल गया → जंगल में गया → बहुत खतरा → खतरा → कमज़ोर”: EX → EW → CR → EN → VU। Threatened = CR+EN+VU।

Ramsar is the oldest of the modern global intergovernmental MEAs for a specific ecosystem type. Its mission is conservation and wise use of all wetlands through local and national actions and international cooperation, as a contribution to sustainable development. “Wetlands” under Ramsar are defined broadly — marshes, lakes, rivers, peatlands, mangroves, coral reefs, and even human-made sites like tanks and reservoirs can qualify.

1. Designation of suitable wetlands to the List of Wetlands of International Importance (Ramsar List) and ensuring their effective management.
2. Wise use of all wetlands in the Party’s territory (not only listed ones) — maintaining ecological character within sustainable development.
3. International cooperation on shared wetlands, river basins, and migratory species pathways.

रामसर तीन खम्भे — “लिस्ट करो, समझदारी से बरतो (wise use), मिलकर बचाओ”। मोंट्रू रिकॉर्ड = “मुसीबत वाली रामसर साइटें”। विश्व वेटलैंड दिवस = 2 फ़रवरी (रामसर जन्मतिथि)।

There are nine criteria grouping sites of international importance (representative/unique wetlands; species/ecological communities; waterbirds; fish; other taxa). Once listed, the ecological character should be maintained. The Montreux Record is a register of listed sites where changes in ecological character have occurred, are occurring, or are likely to occur because of human interference — a danger/watch list inside Ramsar, not a separate convention.

COP (every 3 years typically), Standing Committee, Scientific & Technical Review Panel (STRP), and the Secretariat hosted by IUCN in Gland. World Wetlands Day is celebrated on 2 February.

• India’s Ramsar count has expanded rapidly in recent years; always verify the latest official count from MoEFCC / Ramsar before quoting a number in Mains.
• Classic early sites discussed in older notes include Chilika Lake (Odisha) and Keoladeo (Bharatpur). Chilika is also famous for Irrawaddy dolphins and lagoon ecology; Keoladeo for migratory waterfowl.
• Indian sites frequently associated with the Montreux Record in standard materials: Keoladeo National Park and Loktak Lake — re-check the live Montreux list before the exam.
• Domestic framework: Wetlands (Conservation and Management) Rules, 2017; National Plan for Conservation of Aquatic Ecosystems (NPCA); state wetland authorities.

The United Nations Convention to Combat Desertification addresses desertification and mitigates the effects of drought, particularly in Africa, but with global membership. It focuses on arid, semi-arid and dry sub-humid areas. Implementation emphasises bottom-up participatory approaches, National Action Programmes, and synergy with climate and biodiversity agendas.

LDN is a state whereby the amount and quality of land resources necessary to support ecosystem functions and services remains stable or increases. It is reflected in SDG Target 15.3. Parties set voluntary LDN targets. India has announced LDN targets and links restoration programmes (afforestation, watershed, agroforestry) to this frame.

UNCCD = “धूल–सूखा–ज़मीन” कन्वेंशन। LDN = भूमि क्षरण तटस्थता — जितना बिगड़े उतना सुधारो (net zero land degradation)। SDG 15.3 से जोड़ो।

COP; Committee on Science and Technology (CST); Committee for the Review of the Implementation of the Convention (CRIC). The Great Green Wall (Africa) and similar landscape initiatives often appear as CA examples of UNCCD-aligned action.

The Vienna Convention for the Protection of the Ozone Layer created the cooperative framework. The Montreal Protocol on Substances that Deplete the Ozone Layer is the control treaty — widely called the most successful MEA because it established binding, time-bound phase-out schedules for ozone-depleting substances (CFCs, halons, methyl bromide, HCFCs, etc.), supported by the Multilateral Fund for developing-country compliance.

• ODS vs GHG: classic ODS destroy stratospheric ozone. Some replacements (HFCs) do not deplete ozone much but are potent greenhouse gases — which is why Kigali matters for climate.
• Article 5 Parties: developing countries with delayed control schedules and financial support eligibility.
• Kigali Amendment (2016): phasedown of HFCs under Montreal. Different country baselines and freeze/reduction calendars apply; India is an Article 5 Party with a later schedule than non-A5 Parties.

India Cooling Action Plan (ICAP) — aims to reduce cooling demand, refrigerant transition, and energy efficiency together. Domestic ODS rules under environment/ozone cell administration are the bureaucratic side rarely asked in depth, but ICAP + Kigali is high-yield.

ओज़ोन कहानी — “वियना ने छतरी दी, मॉन्ट्रियल ने ODS काटी, किगाली ने HFC घटाई”। ODS ≠ HFC; HFC ओज़ोन नहीं खाते, जलवायु गरम करते हैं।

Basel controls the transboundary movements of hazardous wastes and other wastes and obliges Parties to ensure environmentally sound management (ESM). It was a response to dumping of hazardous wastes in developing countries. Exports generally require Prior Informed Consent of the importing (and often transit) State.

• Ban Amendment: prohibits certain hazardous waste exports from developed (Annex VII) to developing countries — political equity story.
• Plastic waste amendments (2019): brought many plastic waste streams into a clearer PIC framework — directly relevant to global waste trade and India’s import restrictions / PWM Rules debates.

Basel is about wastes in movement and management, not a chemical ban list like Stockholm.

बेसल = “कचरा सीमा पार तभी जब इजाज़त हो” (PIC + ESM)। प्लास्टिक वेस्ट 2019 संशोधन याद रखो।

Rotterdam creates a legally binding Prior Informed Consent (PIC) procedure for certain hazardous chemicals and pesticides in international trade. When a chemical is listed in Annex III, exporting Parties must ensure that exports do not proceed contrary to the importing Party’s documented import decision.

Critical trap: Rotterdam does not automatically ban a chemical worldwide. It empowers informed decisions. Listing fights at COP (e.g. over particular pesticides) are recurring CA items.

रॉटरडैम = “पहले पूछो, फिर भेजो” (Prior Informed Consent)। लिस्टिंग ≠ दुनियाभर में बैन।

Stockholm targets Persistent Organic Pollutants — chemicals that remain intact for long periods, become widely distributed, accumulate in fatty tissue, and are toxic to humans and wildlife. The Convention requires Parties to eliminate or restrict production/use and to reduce unintentional releases.

• Annex A: elimination (with specific exemptions possible).
• Annex B: restriction (e.g. DDT historically framed for acceptable purpose of disease vector control under conditions).
• Annex C: unintentionally produced POPs (e.g. dioxins/furans) — best available techniques / best environmental practices.

New chemicals can be added by COP after scientific review (POPs Review Committee). India’s National Implementation Plan and domestic regulations on POPs appear as applied questions.

स्टॉकहोम POPs — Annex याद: “A हटाओ, B बाधित करो, C अनजाने उत्सर्जन घटाओ” (Eliminate / Restrict / Unintentional)।

Minamata addresses the full life cycle of mercury: supply (mines), trade, mercury-added products (certain batteries, lamps, cosmetics, etc. on schedules), manufacturing processes, artisanal and small-scale gold mining (ASGM), air emissions, releases to land/water, environmentally sound interim storage, mercury wastes, and contaminated sites.

It is the chemicals convention most tightly tied to a public-health disaster narrative (methylmercury poisoning in Minamata, Japan). Distinguish it from Stockholm (many POPs) and Basel (waste movements).

मिनामाता = पारा (mercury) की पूरी ज़िंदगी कंट्रोल — खान से कचरे तक। नाम जापान की बीमारी से।

The three conventions share a chemicals-and-waste family resemblance and often hold coordinated COPs (BRS COPs) to exploit administrative synergies. Still, their legal triggers differ:

The United Nations Convention on the Law of the Sea is often called the “constitution of the oceans.” It codifies maritime zones measured mainly from baselines, balances coastal-state rights with freedoms of navigation, and creates institutions for the deep seabed and dispute settlement.

• ITLOS (Hamburg): International Tribunal for the Law of the Sea.
• ISA (Kingston): organises and controls activities in the Area, especially deep-sea mining regime (exploration regulations exist; exploitation regulations have been politically contested — CA hotspot).
• CLCS: Commission on the Limits of the Continental Shelf — makes recommendations on outer CS limits beyond 200 nm.
• DOALOS: UN Division for Ocean Affairs and the Law of the Sea — secretariat support functions.

UNCLOS दूरियाँ — “बारह राज, चौबीस जाँच, दो सौ दौलत”: 12 nm Territorial Sea (संप्रभुता), 24 nm Contiguous (customs/fiscal/immigration/sanitary), 200 nm EEZ (संसाधन अधिकार)। Area = “मानव जाति की साझी विरासत” (Common Heritage) — ISA Kingston।

Formally the Agreement under UNCLOS on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction. It fills governance gaps on the high seas and in the Area regarding biodiversity — places where UNCLOS set the stage but lacked a modern package on MPAs, benefit sharing from marine genetic resources, and standardised EIAs.

1. Marine Genetic Resources (MGRs) including digital sequence information debates, and fair & equitable benefit sharing.
2. Area-based management tools, including Marine Protected Areas on the high seas.
3. Environmental Impact Assessments for activities with potential effects in ABNJ.
4. Capacity-building and transfer of marine technology, especially for developing countries.

Entry into force depends on reaching the required number of ratifications — treat the in-force status as a living CA fact. Links tightly to CBD’s 30×30 target because much of the ocean lies beyond EEZs.

BBNJ चार खम्भे — “जेनेटिक बाँटो, MPA बनाओ, EIA करो, क्षमता दो”: MGRs + benefit sharing, area-based tools/MPAs, EIAs, capacity-building।
