Explanation :
Circular Economy (CE):
A circular economy is an economic system designed to be restorative and regenerative by intention. Its core principles are:
- Design out waste and pollution.
- Keep products and materials in use at their highest utility and value.
- Regenerate natural systems rather than simply extracting resources.
From this definition we derive two fundamental outcomes:
• A significant reduction in the input of virgin raw materials, since products and materials are reused, remanufactured, or recycled (Principle 2).
• A drastic minimization of waste and by-products in production processes through improved design, closed-loop material flows, and resource-efficient manufacturing (Principles 1 & 2).
Examination of the statements:
Statement II: “Circular economy reduces the use of raw materials as inputs.”
– Directly follows from Principle 2: Keeping materials in use replaces the need for virgin resource extraction.
– Therefore, Statement II is correct.
Statement III: “Circular economy reduces wastage in the production process.”
– Follows from Principles 1 and 2: Designing out waste and implementing closed-loop systems curtails production losses and by-products.
– Therefore, Statement III is correct.
Statement I: “Circular economy reduces the emissions of greenhouse gases.”
– By avoiding energy-intensive extraction, refining, manufacturing, and disposal of virgin materials and waste, a circular economy lowers CO₂ and other GHG emissions across the life cycle.
Do Statements II and III explain Statement I?
• Reduced virgin‐material inputs (II) avoid the large energy consumption and associated emissions of mining and processing.
• Reduced production waste (III) eliminates waste-incineration or landfill methane emissions and improves energy efficiency per unit of output.
Hence both II and III are not only correct but also jointly explain how a circular economy achieves the GHG-emission reductions asserted in Statement I.
Conclusion: Option (a) is the correct choice.
