Not attemptedCorrect Answer: (a) long-term damage done by a tonne of CO₂ emissions in a given year
The Social Cost of Carbon (SCC) is officially defined as the monetary estimate of the long-term global damage caused by emitting one additional metric tonne of CO₂ in a given year; it converts future climate-related losses (agriculture, health, property, energy, etc.) into present-value dollars. Therefore option (a) is correct. The other options misinterpret SCC: it is unrelated to a nation’s fuel requirement (b), to expenditure by climate refugees (c), or to an individual’s personal footprint (d).
