Arrange the following events in chronological order and select the correct answer from the codes given below: I. Rio Earth Summit II. Publication of Brundtland Commission Report III. Enforcement of Montreal Protocol IV. Publication of 'The Limits to Growth' Report
- (a)I, IV, III, II
- (b)IV, II, III, I
- (c)IV, III, II, I
- (d)IV, I, III, II
Correct — B, IV-II-III-I. By year: (IV) the Club of Rome's 'The Limits to Growth' was published in 1972; (II) the Brundtland Commission Report 'Our Common Future' was published in 1987; (III) the Montreal Protocol, though adopted in 1987, entered into force (was enforced) on 1 January 1989; and (I) the Rio Earth Summit (UN Conference on Environment and Development) was held in 1992. That sequence is IV, II, III, I.
- (a)I, IV, III, II — Puts the Rio Earth Summit (1992) first, but Rio is actually the last of the four; 'The Limits to Growth' (1972) is the earliest.
- (c)IV, III, II, I — Correctly starts with 'The Limits to Growth' (1972) but then places the Montreal Protocol's enforcement (1989) before the Brundtland Report (1987), reversing those two.
- (d)IV, I, III, II — Wrongly slots the Rio Summit (1992) second and ends with the Brundtland Report; in reality Brundtland (1987) is early and Rio (1992) is last.
These four are landmarks in the rise of the sustainable-development and global-environment agenda. 'The Limits to Growth' (1972) warned that unchecked growth would strain planetary limits; the Brundtland Report 'Our Common Future' (1987) popularised the definition of sustainable development; the Montreal Protocol (adopted 1987, in force 1989) began phasing out ozone-depleting substances; and the Rio Earth Summit (1992) produced Agenda 21, the UNFCCC and the Convention on Biological Diversity.
The subtle trap is the Montreal Protocol: it was adopted in 1987 (same year as the Brundtland Report) but the question deliberately says 'Enforcement', i.e. entry into force on 1 January 1989 — placing it after Brundtland. Anchor the ends first (Limits to Growth 1972 is earliest, Rio 1992 latest), then order Brundtland 1987 before Montreal's 1989 enforcement.
- 'The Limits to Growth' (Club of Rome) — 1972.
- Brundtland Commission (WCED) report 'Our Common Future' — 1987; gave the classic definition of sustainable development.
- Montreal Protocol — adopted 1987 but entered into force (enforced) on 1 January 1989.
- Rio Earth Summit (UNCED) — June 1992; produced Agenda 21, UNFCCC and the CBD.
- 1972 — 'The Limits to Growth' (IV)
- 1987 — Brundtland Report 'Our Common Future' (II)
- 1989 — Montreal Protocol enters into force (III)
- 1992 — Rio Earth Summit / UNCED (I)
Order IV-II-III-I (option b). Note: Montreal Protocol was adopted 1987 but ENFORCED 1 Jan 1989, so it follows the 1987 Brundtland Report.
- Confusing the Montreal Protocol's adoption year (1987) with its enforcement year (1989) — the question specifically asks about enforcement.
- Mixing up the Stockholm Conference (1972) with 'The Limits to Growth' (also 1972) or with the Rio Summit (1992).
UPSC/UPPSC ask these as chronology or matching questions — pairing each summit/report with its year and outcome (Brundtland with 'sustainable development', Montreal with ozone, Rio with Agenda 21/UNFCCC/CBD).
Sustainable development is described as the development that meets the needs of the present without compromising the ability of future generations to meet their own needs. In this perspective, inherently the concept of sustainable development is intertwined with which of the following concepts?
- (a) Social justice and empowerment
- (b) Inclusive Growth
- (c) Globalization
- (d) Carrying capacity
Answer(d) Carrying capacity — the Brundtland definition of sustainable development is inherently tied to not exceeding the environment's carrying capacity.
Directly tests the Brundtland Commission's definition of sustainable development — event II in this UPPSC chronology.
Which one of the following is associated with the issue of control and phasing out of the use of ozone-depleting substances?
- (a) Bretton Woods Conference
- (b) Montreal Protocol
- (c) Kyoto Protocol
- (d) Nagoya Protocol
Answer(b) Montreal Protocol — it regulates and phases out ozone-depleting substances such as CFCs and HCFCs.
Tests the Montreal Protocol — event III in this UPPSC chronology — as the treaty on ozone-depleting substances.
Consider the following statements: 1. The Sustainable Development Goals were first proposed in 1972 by a global think tank called the 'Club of Rome'. 2. The Sustainable Development Goals have to be achieved by 2030. Which of the statements given above is/are correct?
- (a) 1 only
- (b) 2 only
- (c) Both 1 and 2
- (d) Neither 1 nor 2
Answer(b) 2 only — the SDGs are to be met by 2030; the Club of Rome published 'The Limits to Growth' in 1972 (not the SDGs).
Anchors the Club of Rome and its 1972 'The Limits to Growth' report — event IV, the earliest item in this UPPSC chronology.
- practice — not a real PYQ
The classic definition of 'sustainable development' as meeting present needs without compromising future generations was popularised by:
- (a)The Brundtland Commission Report (Our Common Future)
- (b)The Rio Declaration
- (c)The Stockholm Declaration
- (d)The Kyoto Protocol
Answer(a) The Brundtland Commission Report (Our Common Future), 1987.
- practice — not a real PYQ
Which of the following was an outcome of the 1992 Rio Earth Summit? 1. Agenda 21 2. UN Framework Convention on Climate Change 3. Convention on Biological Diversity
- (a)1 only
- (b)1 and 2 only
- (c)2 and 3 only
- (d)1, 2 and 3
Answer(d) 1, 2 and 3 — Agenda 21, the UNFCCC and the CBD all emerged from the Rio Earth Summit.
