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?
Explanation
Statement I is correct: The circular economy model aims to reduce resource extraction, encourage recycling and reuse, and design out waste. All these reduce energy consumption and emissions. Greenhouse gas (GHG) emissions are reduced in several ways:
Lower extraction and processing of virgin materials (which is carbon-intensive). Emphasis on reuse, recycling, and resource efficiency. Waste reduction leads to less landfill methane and less incineration. Impact organisation Circle Economy’s Circularity Gap Report 2021 finds that circular economy strategies can cut global greenhouse gas emissions by 39%.
Statement II is correct: By emphasizing reuse, refurbishment, remanufacturing, and recycling, the circular economy significantly reduces the need for raw materials as inputs in production processes, conserving natural resources.
Statement III is correct: The circular economy focuses on reducing wastage in production by improving process efficiency, redesigning products for durability and easy repair, and adopting sustainable manufacturing practices. Statements II and III explain Statement I: Reducing raw material use (Statement II) and cutting production wastage (Statement III) both contribute to lower energy consumption and fewer emissions, which leads to a reduction in overall greenhouse gas emissions (Statement I).
You can try, The "NOT" approach for all statements, this tests the improbability of negating a statement--if denying its impact seems highly unlikely, the statement is plausibly true. For example: Circular economy do NOT reduces the use of raw materials as inputs." Denial would contradict the very essence of the circular economy. So denial is implausible, meaning S2 is true. Similarly apply this approach in all three statements and you can observe all are true and logically correct explanation of S1.
