Environment & Ecology question from UPSC CSE-Prelims, 2026

Consider the following statements with reference to India's response to climate change:
I. India's Long-Term Low Emission Development Strategy (LT-LEDS) is a crucial tool for achieving net-zero emissions by 2070.
II. India's 4th Biennial Update Report (BUR-4) submitted in December, 2024 recorded around 8% decrease in Greenhouse gas emissions in 2020 over 2019.
III. Climate-resilient development necessarily depends on quick and short-term achievement of emission reduction targets.

Which of the following relationships among the above statements is/are correct?
1. Statement I is empirically supported by statement II.
2. Statement III contradicts the approach implicit in statement I.
3. Statement I and statement III together establish the premise of long-term sustainability.

Correct Answer: Option B — 1 and 2
Explanation of the Statements:
Statement I is true: India formally submitted its Long-Term Low-Emission Development Strategy (LT-LEDS) at COP27, outlining the transition pathway to achieve its net-zero emissions target by 2070.

Statement II is true: India's 4th Biennial Update Report (BUR-4) recorded a significant drop in greenhouse gas emissions in 2020 compared to 2019. This drop was empirically driven by the economic slowdown and lockdowns during the COVID-19 pandemic.

Statement III is false/flawed: Climate-resilient development does not necessarily depend on "quick and short-term" targets. In fact, true climate resilience requires sustained, long-term structural transitions across decades (like the 2070 net-zero target).

Evaluation of the Relationships:
Relationship 1 is correct: Statement I sets a long-term goal (net-zero by 2070), and Statement II provides the empirical data (actual recorded emission drops) that supports the feasibility and downward trajectory needed for that long-term strategy.

Relationship 2 is correct: Statement III promotes a "quick and short-term" approach, which directly contradicts the fundamental philosophy of Statement I, which is explicitly a long-term strategy (LT-LEDS).

Relationship 3 is incorrect: Statement III cannot establish a premise for sustainability because its short-term focus contradicts the long-term planning required for sustainable development.
