UPSC Prelims 2025 GS Paper I · Q39 of 99 Environment & Ecology medium

Consider the following statements : Statement I : Circular economy reduces the emissions of greenhouse gases. Statement II : Circular economy reduces the use of raw materials as inputs. Statement III : Circular economy reduces wastage in the production process. Which one of the following is correct in respect of the above statements?

  1. (a) Both Statement II and Statement III are correct and both of them explain Statement I ✓ UPSC's answer
  2. (b) Both Statement II and Statement III are correct but only one of them explains Statement I
  3. (c) Only one of the Statements II and III is correct and that explains Statement I
  4. (d) Neither Statement II nor Statement III is correct

Why the answer is (a)

• A circular economy keeps materials in use through reuse, repair, remanufacturing and recycling, in contrast to the linear 'take-make-dispose' model.

• Statement II is correct: by recovering materials from used products it cuts the extraction of virgin raw materials.

• Statement III is correct: designing out waste and by-products reduces wastage during production.

• Both explain statement I: extracting and processing raw materials and dealing with waste are energy-intensive and emission-heavy, so reducing both lowers greenhouse-gas emissions — roughly 45% of global emissions come from how materials are made and used.

• Hence option (a).

Why the other options are wrong

(b) Both Statement II and Statement III are correct but only one of them explains Statement I
Both reduced raw-material use and reduced waste lower emissions, so both explain I.
(c) Only one of the Statements II and III is correct and that explains Statement I
Both II and III are correct.
(d) Neither Statement II nor Statement III is correct
Both II and III are correct.
