## Comments Any additional remarks or notes about the proposal. ## Climate Model Used The climate model(s) used in deriving the SCC (e.g., DICE, FUND, PAGE). ## Currency The currency in which the SCC value is denominated (e.g., USD, GBP). ## Damage Categories Included A list of damage categories factored into the calculation (e.g., health impacts, agricultural losses, property damages). ## Discount Rate The discount rate(s) used in the calculation of the SCC (e.g., 3%, 2%, 1%). ## Economic Model Used The economic model(s) or framework applied in calculating costs. ## Equity Weighting Whether equity weighting was applied to account for distributional impacts across regions or populations. ## Geographic Scope The geographic region or scope for which the SCC applies (e.g., global, national, state-level). ## Inflation Adjustment Year The base year for inflation adjustment if values are adjusted for inflation. ## Methodology A brief description of the methodology used to calculate the SCC (e.g., integrated assessment model, empirically derived estimate). ## Policy Context The policy application or context for which the SCC was intended (e.g., regulatory impact analysis, carbon tax setting). ## Proposal Name Name or identifier of the social cost of carbon proposal. ## Proposal Year The year the SCC estimate was proposed or published. ## Range High If applicable, the upper bound of a range provided for the SCC estimate. ## Range Low If applicable, the lower bound of a range provided for the SCC estimate. ## Range Average If the social cost of carbon is stated as a range, then the mathematical average is also provided. ## Source Document The name of the report or publication where the estimate is documented. ## Source Organization The organization or entity responsible for producing the SCC estimate (e.g., EPA, Interagency Working Group, New York DEC). ## Time Horizon The time period over which the damages are calculated (e.g., 100 years, indefinite). ## Uncertainty Notes Notes on uncertainties associated with the estimate (e.g., climate sensitivity, economic assumptions). ## Value The numerical value of the SCC estimate. ## Value Units The units in which the SCC is expressed (e.g., $/ton CO2, £/ton C).
