UPSC GS Paper III: Environment - International Environmental Agreements Basel Stockholm Minamata

Must‑Know (20–25 detailed bullets)

• Basel Convention (1989) – regulates transboundary movements of hazardous wastes and their disposal; entered into force in 1992, India ratified in 1992.
• Prior Informed Consent (PIC) procedure under Basel requires exporting countries to notify and obtain consent from importing and transit countries before shipment of hazardous waste.
• Ban Amendment (1995) to Basel Convention – prohibits all exports of hazardous wastes from OECD, EU, and Liechtenstein to non-OECD countries; became legally binding in 2019 after 66th ratification.
• India’s Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016 – align with Basel obligations, prohibit import of solid plastic waste except under specific industrial conditions.
• Stockholm Convention (2001) – targets 12 initial persistent organic pollutants (POPs) known as “dirty dozen”, including DDT, PCBs, dioxins; entered into force in 2004.
• India ratified Stockholm Convention in 2006; National Implementation Plan (NIP) submitted to UNEP in 2007 identifying sources, usage, and disposal practices of POPs.
• Endosulfan – listed under Stockholm Convention in 2011 (COP5); India opposed initially but accepted after Kerala’s health crisis in Kasaragod district linked to aerial spraying.
• Minamata Convention (2013) – first global treaty on mercury control, adopted in Kumamoto, Japan; entered into force in 2017, India ratified in 2018.
• Artisanal and small-scale gold mining (ASGM) – largest source of mercury emissions globally; targeted under Minamata for phase-down, though not outright banned.
• India’s National Mercury Action Plan (NMAP) – developed in 2022 to meet Minamata obligations, focusing on phasing out mercury in thermometers, sphygmomanometers, and certain cosmetics.
• Article 3 of Minamata Convention – bans new mercury mines and phases out existing ones within 15 years of entry into force for each party.
• Article 4 of Basel Convention – requires parties to minimize generation of hazardous waste and manage it as close as possible to its source.
• Rotterdam Convention – operates PIC procedure for certain hazardous chemicals and pesticides in international trade; often linked with Basel and Stockholm under “Chemicals Conventions”.
• India is party to all three: Basel, Rotterdam, Stockholm (BRS), and Minamata, but not to the Bamako Convention (Africa-specific hazardous waste ban).
• Basel Convention’s Plastic Waste Amendments (2019) – added mixed, contaminated, and difficult-to-recycle plastic wastes to Annex II (wastes requiring special consideration); effective Jan 1, 2021.
• India banned import of solid waste for recycling under Basel alignment via 2019 amendment to Hazardous Wastes Rules.
• Stockholm Convention’s Annex A (Elimination), Annex B (Restriction), Annex C (Unintentional production) – guide country-specific action on POPs reduction.
• DDT – allowed under Stockholm for vector control (malaria) despite global elimination goal; India is one of the few producers under WHO exemption.
• India produces DDT through Hindustan Insecticides Limited (HIL) for public health use, consistent with Stockholm’s specific exemption clause.
• Minamata disease – methylmercury poisoning in Japan (1950s) caused by industrial discharge into Minamata Bay; led to neurological damage and birth defects, named after the location.
• UNEP hosted negotiations for Minamata Convention; adopted in October 2013, signed by 92 countries initially.
• Basel Convention has 190 parties; USA has signed but not ratified, hence not legally bound.
• Stockholm Convention currently lists 30 POPs (as of COP10, 2023), including PFOS, PFOA, and short-chain chlorinated paraffins.
• India’s National Green Tribunal (NGT) has referenced Basel principles in cases involving illegal e-waste imports, linking transboundary waste movement to environmental harm.
• E-waste (Management) Rules, 2022 – incorporate extended producer responsibility (EPR) in line with Basel’s emphasis on waste accountability.

Difficulty Level

Intermediate – requires understanding of treaty-specific obligations, amendments, and India’s implementation mechanisms; frequent overlap with current environmental policies.

Common UPSC Traps (3–5 factual traps)

Trap: Minamata Convention bans all use of mercury in products – Fact: It allows continued use in certain products (e.g., dental amalgam) and exempted industrial processes, with phase-out timelines under Article 4.

Trap: India is not a party to the Basel Convention – Fact: India ratified Basel in 1992; strengthened compliance via 2016 and 2019 domestic rule amendments.

Trap: Stockholm Convention completely bans DDT – Fact: Annex B allows DDT for disease vector control (malaria) with reporting requirements; India uses it under WHO guidelines.

Trap: Rotterdam Convention bans hazardous chemicals – Fact: It only mandates Prior Informed Consent (PIC) for listed chemicals in trade; does not prohibit use or import.

Practice MCQs (5–7 questions)

Question: Which of the following statements best describes the Ban Amendment to the Basel Convention?
A) It prohibits the export of all electronic waste to developing countries
B) It bans the transboundary movement of hazardous wastes between OECD and non-OECD countries
C) It requires prior informed consent for all plastic waste shipments
D) It mandates the complete phase-out of mercury-containing devices by 2025
Answer: B
Explanation: The Ban Amendment (1995) prohibits exports of hazardous wastes from OECD, EU, and Liechtenstein to non-OECD countries.
Why others fail: A is incorrect because e-waste is covered under broader Basel framework, not exclusively by Ban Amendment.

Question: Under the Stockholm Convention, which of the following substances is permitted for use in India despite being a persistent organic pollutant?
A) Polychlorinated biphenyls (PCBs)
B) Hexachlorobenzene
C) DDT
D) Mirex
Answer: C
Explanation: DDT is allowed under Annex B for vector control in malaria-endemic regions; India uses it under specific exemption.
Why others fail: A is tempting because PCBs were historically used, but their production and use are fully prohibited under Annex A.

Question: The Minamata Convention is primarily aimed at reducing the risks associated with:
A) Carbon tetrachloride emissions
B) Lead in petrol
C) Mercury and its compounds
D) Sulphur hexafluoride in electrical equipment
Answer: C
Explanation: The Minamata Convention targets anthropogenic emissions and releases of mercury and mercury compounds.
Why others fail: B is associated with UNEP’s Partnership for Clean Fuels and Vehicles, not Minamata.

Question: Which of the following correctly matches an international environmental agreement with its key mechanism?
A) Basel Convention – Prior Informed Consent for hazardous chemicals
B) Rotterdam Convention – Control of transboundary movements of hazardous wastes
C) Stockholm Convention – Global elimination of persistent organic pollutants
D) Minamata Convention – Ban on all forms of plastic waste trade
Answer: C
Explanation: Stockholm Convention aims to eliminate or restrict POPs; PIC is central to Rotterdam, not Basel (which focuses on waste movement).
Why others fail: A is incorrect because PIC for chemicals is under Rotterdam, not Basel.

Question: India’s ban on import of solid plastic waste is aligned with which of the following?
A) Rotterdam Convention’s Annex III
B) Basel Convention’s 2019 Plastic Waste Amendments
C) Stockholm Convention’s Annex C
D) Minamata Convention’s Article 6
Answer: B
Explanation: The 2019 Basel amendments added plastic waste to Annex II and require prior informed consent for exports.
Why others fail: A is incorrect because Annex III of Rotterdam applies to chemicals, not plastic waste.
