उत्तर और व्याख्या · explanation in English
Answer: (a) प्रदत्त वर्ष में एक टन CO₂ के उत्सर्जन से होने वाली दीर्घकालीन क्षति
The Social Cost of Carbon is the money value of the long-term damage caused by one extra tonne of carbon dioxide emitted in a given year. Governments use it to weigh the benefits of cutting emissions against the costs of a policy.
- ✓ (a) This is the standard definition: a measure, in money terms, of the long-term damage done by a tonne of CO2 emitted in a given year; the same figure equals the damage avoided by cutting that tonne.
- ✗ (b) This describes a country's fossil-fuel demand, which is not a monetary damage measure.
- ✗ (c) The cost of adaptation by a climate refugee is not what the term measures; it values damage from emissions.
- ✗ (d) An individual's contribution is a personal carbon footprint, not the Social Cost of Carbon.
Remember · Social Cost of Carbon = money value of the long-term damage from one extra tonne of CO2 emitted in a year; equally, the benefit of avoiding it.
