Environment & Ecology

📘 CDS Current Affairs · CFC08

Environment & Ecology carries low-to-medium weightage in CDS but the questions are highly specific: exact COP number, the specific outcome of a summit, what the Panchamrit targets are, which species has what population. Knowing the right number (COP28 = Dubai; Loss & Damage Fund; fossil fuel language) is the difference between right and wrong.

📌 CDS Pattern — Environment & Ecology (2022–2025):
• COP summits: host country/city + key outcome  |  • India’s commitments: Panchamrit 5 points exactly
• Wildlife: population numbers + project names  |  • Ramsar sites: India’s count + new additions
• Conventions: Montreal, Paris, Ramsar — what each covers  |  • ISFR: India’s forest cover numbers

1. Climate Summits & COP Outcomes

🌎 COP Summits — Key Outcomes

  • COP26 (Glasgow, Scotland, 2021): India announced Panchamrit targets. “Phase down” (NOT “phase out”) coal — India & China insisted on weaker language. Glasgow Climate Pact. Climate Finance: $100 billion/year pledge (not fully met). Loss and Damage: discussed but no fund created yet.
  • COP27 (Sharm el-Sheikh, Egypt, 2022): Loss and Damage Fund agreed in principle (historic milestone for small island states and developing nations). No new mitigation commitments. India launched “Mission LiFE” (Lifestyle for Environment) at COP27 — PM Modi’s initiative promoting sustainable individual lifestyles.
  • COP28 (Dubai, UAE, Nov–Dec 2023):
    • First Global Stocktake: Under Paris Agreement, first formal assessment of progress toward 1.5°C goal. Result: world far off track.
    • Loss and Damage Fund operationalised: Hosted by World Bank; initial contributions: UAE USD 100M, USA USD 17.5M, UK USD 40M, EU USD 225M. Total pledged: ~USD 700 million (developing nations need USD 400 billion annually).
    • UAE Consensus — Historic fossil fuel language: “Transitioning away from fossil fuels in energy systems” — first-ever COP text mentioning fossil fuels. Islands wanted “phase out;” oil producers blocked; compromise = “transition away.”
    • Tripling renewable energy capacity globally by 2030; doubling energy efficiency.
    • Methane emissions reduction pledge (Global Methane Pledge).
  • COP29 (Baku, Azerbaijan, Nov 2024): NCQG (New Collective Quantified Goal for Climate Finance). Agreed: USD 300 billion/year from developed nations to developing nations by 2035. Developing nations (India, G77) demanded USD 1.3 trillion. India called the USD 300 billion target “abysmally low.” Also: Carbon markets (Article 6) finalised.
  • COP30 (Belem, Brazil, Nov 2025): Countries to submit enhanced NDCs (Nationally Determined Contributions). Belem Health Action Plan (climate and health linkages). Amazon hosting = symbolic (deforestation focus).

2. India’s Climate Commitments

🌿 Panchamrit Goals (Announced COP26, 2021) — India’s NDC

  • 1. 500 GW: Achieve 500 GW non-fossil fuel electricity capacity by 2030.
  • 2. 50% Renewable: Meet 50% of energy requirements from renewable energy by 2030.
  • 3. 1 Billion Tonnes CO2: Reduce total projected carbon emissions by 1 billion tonnes by 2030.
  • 4. 45% Carbon Intensity: Reduce carbon intensity of GDP by 45% (from 2005 level) by 2030.
  • 5. Net-Zero by 2070: Achieve net-zero carbon emissions target by 2070.
⚠ CDS Direct Question: “What is India’s net-zero target year?” → 2070 (NOT 2050, which is USA/EU target; NOT 2060, which is China’s target). India argues it is a developing country and cannot adopt the same timeline as historically-high emitting developed nations.
  • Renewable Energy Progress (2024): India’s total installed renewable capacity crossed 200 GW (solar ~90 GW + wind ~46 GW + hydro ~47 GW + others). On track to reach 500 GW by 2030 (needs ~300 GW more).
  • National Green Hydrogen Mission: Rs 19,744 crore. Target: produce 5 million tonnes (MT) of green hydrogen/year by 2030. Export potential to Europe and Japan. Green hydrogen = produced using renewable energy electrolysis (not fossil fuels).
  • International Solar Alliance (ISA): India-France joint initiative launched COP21 (Paris, 2015). HQ: Gurugram, India. 120+ member nations. Aims to mobilise USD 1 trillion for solar energy by 2030. World Solar Bank under ISA.
  • One Sun One World One Grid (OSOWOG): India’s initiative for a global interconnected electricity grid powered by solar energy. Announced at COP26. Led by Power Ministry.
  • LIFE Movement (Lifestyle for Environment): PM Modi launched at COP26 (2021); officially launched at UN (Oct 2022). Promotes sustainable consumption: avoid single-use plastic, save water/energy, eat local. Global campaign with 1 billion individual pledges target.

3. Biodiversity & Conservation

🐙 Wildlife Conservation — Key Data

  • Project Tiger (1973): India’s tiger population census 2022: 3,167 tigers. India has ~70% of world’s wild tiger population. 53 Tiger Reserves in India.

4. Environmental Policies & Reports

📋 Key Reports & Acts

  • India State of Forest Report (ISFR 2023): Total forest cover: 7,15,343 sq km (21.76% of India’s geographic area). Tree cover: 2,91,196 sq km. Total forest + tree cover: 1,006,539 sq km (30.55%). States with most forest: MP > Arunachal Pradesh > Chhattisgarh. Net increase in forest cover: +1,445 sq km (2021 to 2023). Northeast India: still has most forests but declining due to jhum cultivation.
  • Forest Conservation Amendment Act 2023: Denotifies land within 100 km of international borders for strategic projects without FC Act permission. Exempts plantations on private land. Critics: weakens 1980 Forest Conservation Act; may allow forest diversion.
  • National Clean Air Programme (NCAP): Target: 40% reduction in PM2.5 and PM10 concentration by 2026 (base year 2017). 131 non-attainment cities identified. Ministry: Environment, Forest & Climate Change.
  • Namami Gange Programme: Rs 20,000 crore; cleaning Ganga. Focus: Sewage Treatment Plants (STPs), riverfront development, bioremediation. Ganga declared “National River.” Success: Dolphin population increasing in Ganga.
  • E-Waste Rules 2022: Extended Producer Responsibility (EPR) for e-waste. Manufacturers must ensure collection & recycling of 60% of items sold annually. Formalises India’s ~3.2 MT/year e-waste management.
  • Plastic Waste Management Rules 2022: Banned 19 categories of single-use plastic from July 1, 2022 (thickness <75 microns). India’s commitment to phase out plastic pollution by 2025 (own target).
  • Glacial Lake Outburst Flood (GLOF) — Sikkim, Oct 2023: South Lhonak Lake burst; devastating floods in Teesta Valley. 50+ deaths; Chungthang dam destroyed. NDRF deployed. Climate change accelerating glacial melting in Himalayas (Himalayan glaciers retreating faster than global average).

🌎 Key Environmental Conventions & Agreements

  • Paris Agreement (2015): Legally binding; limits global warming to well below 2°C (preferably 1.5°C). NDCs (Nationally Determined Contributions) = each country’s self-set climate targets. India’s NDC enhanced (2022): 45% emission intensity reduction; 50% non-fossil energy by 2030.
  • Montreal Protocol (1987): Phase out ODS (Ozone Depleting Substances) — CFCs, HCFCs. Kigali Amendment (2016): also phase down HFCs (used in AC/refrigerants; powerful GHGs). India ratified Kigali (2021). Ozone layer recovering — expected full recovery by 2066 over Antarctica.
  • Convention on Biological Diversity (CBD): Biodiversity conservation, sustainable use, fair sharing of benefits from genetic resources. Secretariat: Montreal. India is a party. Nagoya Protocol (access & benefit sharing) under CBD.
  • CITES (Convention on International Trade in Endangered Species): Regulates wildlife trade. Appendix I = commercial trade banned. Appendix II = trade regulated. Tiger (Appendix I); Rhinoceros (Appendix I). India hosts tigers, rhinos, elephants = key CITES obligations.
  • UN Convention to Combat Desertification (UNCCD): India pledged to restore 26 million hectares of degraded land by 2030. India hosts COP14 of UNCCD (New Delhi, 2019) — first time in Asia.
  • Global Plastics Treaty: UN negotiating a legally binding treaty to end plastic pollution by 2040. India: supports ambitious agreement with production reduction caps.
📝 TOPIC-WISE PYQ
Environment & Ecology — CDS Pattern Questions with Explanations
Q1. The UAE Consensus at COP28 (2023) was described as “historic” for what specific reason? (CDS I 2025)
(a) First time a developing nation hosted COP   (b) First COP text to mention “transitioning away from fossil fuels”   (c) First agreement to set a global net-zero target   (d) First agreement to ban coal globally
Answer: (b) First COP text to mention “transitioning away from fossil fuels” in energy systems
In 29 years of COP negotiations since UNFCCC (1992), no COP agreement had ever mentioned “fossil fuels.” COP28 UAE Consensus included the phrase “transitioning away from fossil fuels in energy systems” for the first time. Small island nations and climate scientists wanted “phase out” language; OPEC nations (Saudi Arabia, UAE, Russia) blocked; compromise = “transition away.” The Loss & Damage Fund was also operationalised at COP28 (agreed at COP27, operationalised at COP28). Global Stocktake = first formal assessment under Paris Agreement of whether countries are on track to meet climate goals (result: far off track).
Q2. What are India’s “Panchamrit” climate targets? What is India’s net-zero year? (CDS II 2023)
(a) 5 targets; net-zero by 2050   (b) 5 targets; net-zero by 2060   (c) 5 targets; net-zero by 2070   (d) 3 targets; net-zero by 2070
Answer: (c) 5 targets; net-zero by 2070
Panchamrit (“five nectars”) announced by PM Modi at COP26, Glasgow (2021). The 5 targets: (1) 500 GW non-fossil capacity by 2030, (2) 50% energy from renewables by 2030, (3) reduce 1 billion tonnes CO2 by 2030, (4) reduce carbon intensity 45% by 2030, (5) net-zero by 2070. India’s net-zero is 2070 (20 years later than USA/EU’s 2050; 10 years later than China’s 2060). India argues equity: developed nations industrialised for 200 years using fossil fuels; India still developing. CDS: all 5 targets tested individually, and the comparison 2050/2060/2070 is frequently confused.
Q3. Project Cheetah’s first translocation batch arrived in India in September 2022. What was unique about this project, and where were the cheetahs brought from? (CDS II 2023)
(a) Kenya; first intra-continental carnivore translocation   (b) Namibia; world’s first inter-continental large carnivore translocation   (c) South Africa; India’s first national park creation for cheetah   (d) Zimbabwe; IUCN-funded rewilding programme
Answer: (b) Namibia; world’s first inter-continental large carnivore translocation
8 cheetahs from Namibia arrived at Kuno National Park (Madhya Pradesh) on September 17, 2022 (PM Modi’s 72nd birthday). A second batch of 12 arrived from South Africa in February 2023. Total: 20 cheetahs. Cheetah was declared extinct in India in 1952 (last 3 individuals shot in 1947 by Maharaja of Surguja/Koriya). This is the world’s first inter-continental (Namibia/South Africa to India) translocation of a large carnivore. Previous translocations were intra-continental (e.g., lions moved within Africa). Site = Kuno NP was originally planned for Asiatic Lion too. Some mortality (7 cheetah deaths by 2024) from injuries, infections — programme under review but continuing.
Q4. India has the most Ramsar sites of any nation. How many does India have, and what does “Ramsar site” designation mean? (CDS I 2024)
(a) 75 sites; UNESCO conservation designation for forests   (b) 85+ sites; internationally important wetlands under the Ramsar Convention (1971)   (c) 42 sites; IUCN Critical Ecosystem Partnership Fund sites   (d) 100 sites; biodiversity hotspots under CBD
Answer: (b) 85+ sites; internationally important wetlands under the Ramsar Convention (1971)
Ramsar Convention (Convention on Wetlands, 1971, signed in Ramsar, Iran) designates wetlands of international importance, especially for waterfowl and biodiversity. India has 85+ Ramsar sites (most in any country as of 2024) covering 1.33 million hectares. India added a record 26 new sites in 2022 alone. Notable Ramsar sites: Chilika Lake (Odisha, 1st Indian Ramsar site, 1981), Loktak Lake (Manipur, floating islands), Wular Lake (J&K, largest freshwater lake in India). Benefits: Ramsar designation brings international conservation attention, funding, monitoring protocols. Not a UNESCO heritage designation (separate); Ramsar = wetlands specifically.
Q5. India’s total tiger population as per the 2022 census was 3,167. This represents approximately what percentage of the world’s wild tiger population? (CDS pattern)
(a) 40%   (b) 55%   (c) 70%   (d) 85%
Answer: (c) approximately 70%
India’s 3,167 tigers (2022 census) out of global wild tiger population of ~4,500 = ~70%. India has 53 Tiger Reserves under Project Tiger (launched 1973; 50th anniversary 2023). Tiger population trajectory: 1,411 (2006) → 3,167 (2022) = 2.2x increase in 16 years. India submitted this census report to the IUCN on Global Tiger Day (July 29, 2023). This makes India the global success story for large carnivore conservation. CDS trick: 70% is the approximate correct proportion; 40% would suggest only a small majority; 85% would imply near-monopoly; 70% is the internationally cited figure.
🔥 ANALYTICAL QUESTIONS
Environment — Multi-Layer Analysis & Convention Distinctions
🤯 T1. What is the difference between the Ramsar Convention, CBD, CITES, and UNFCCC? A CDS question gives one convention name and asks what it covers — how do you distinguish them?
Quick classification table:
Ramsar (1971): WETLANDS only. Internationally important wetlands for waterfowl. India: 85+ sites. Secretariat: Gland, Switzerland.
CBD (1992, Rio): ALL biodiversity. Conservation, sustainable use, fair benefit sharing from genetic resources. Nagoya Protocol (benefit sharing). Kunming-Montreal framework (30x30). Secretariat: Montreal.
CITES (1973): TRADE in wildlife species. Regulates/bans commercial trade. Appendix I = trade banned; Appendix II = regulated. Tiger, rhino, elephant = Appendix I. Secretariat: Geneva.
UNFCCC (1992, Rio): CLIMATE CHANGE. Framework for climate negotiations. Paris Agreement under UNFCCC. COP meetings every year. Secretariat: Bonn, Germany.
Montreal Protocol (1987): OZONE DEPLETING SUBSTANCES (CFCs, HCFCs). Kigali Amendment added HFCs. Most successful environmental treaty.
CDS exam method: Subject → Convention. Wetlands=Ramsar; Trade=CITES; All biodiversity=CBD; Climate=UNFCCC; Ozone=Montreal.
🤯 T2. India’s net-zero target is 2070, while the USA and EU target 2050, and China targets 2060. What is India’s stated justification, and what is the “Common But Differentiated Responsibilities (CBDR)” principle?
India’s justification:
1. Historical emissions equity: Developed nations emitted greenhouse gases during 150+ years of industrialisation (Industrial Revolution 1760s onwards). India only industrialising now. Cumulative historical emissions of USA = 25% of global total; India = <4%.
2. Development rights: India still has 800 million people needing better living standards = energy demand will rise. Asking India to cut emissions means cutting development.
3. Per capita emissions: India’s per capita CO2 = ~2 tonnes/year. USA = ~15 tonnes/year. Equity demands India be given more time.
CBDR Principle (UNFCCC, 1992): Common but Differentiated Responsibilities. All nations share responsibility for climate action (Common) but historical emitters bear greater burden (Differentiated). Developed nations must: cut emissions faster + provide finance + transfer technology to developing nations. This is India’s legal basis for 2070 net-zero and for demanding USD 1 trillion+/year climate finance at COP29.
CDS loves CBDR: “What principle allows developing nations to have different climate targets?” = CBDR.
