Social Cost Of Carbon Calculator

The Social Cost of Carbon (SCC) is a critical metric used to evaluate the economic impact of carbon emissions on society. It represents the estimated cost associated with each additional ton of carbon dioxide emitted into the atmosphere. Accurate estimation of the SCC is essential for making informed policy decisions and addressing climate change.

Formula: The formula for calculating the Social Cost of Carbon is as follows:

SCC = Carbon Emissions / (1 – (1 + Discount Rate)^-Years)


  • SCC is the Social Cost of Carbon.
  • Carbon Emissions are the total emissions in tons.
  • Discount Rate is the rate at which future costs are discounted.
  • Years represent the time horizon over which the SCC is calculated.

How to Use:

  1. Enter the total carbon emissions in tons in the provided input field.
  2. Select the appropriate discount rate from the dropdown menu.
  3. Specify the time horizon in years.
  4. Click the “Calculate” button.
  5. The estimated Social Cost of Carbon will be displayed.

Example: Suppose you want to calculate the SCC for 100 tons of carbon emissions over a 20-year time horizon with a 3% discount rate. Enter the values into the calculator and click “Calculate” to obtain the result.


  1. What is the Social Cost of Carbon (SCC)?
    • The SCC is the estimated economic cost associated with each additional ton of carbon dioxide emissions.
  2. Why is the SCC important?
    • It helps policymakers assess the environmental and economic impacts of carbon emissions and make informed decisions to combat climate change.
  3. What is the discount rate in the formula?
    • The discount rate accounts for the time value of money and reflects the rate at which future costs are valued.
  4. How is the SCC used in policy-making?
    • Governments use the SCC to set carbon pricing, regulate emissions, and develop climate change mitigation strategies.
  5. Is the SCC a fixed value?
    • No, it varies depending on factors like emissions, time horizon, and discount rate.
  6. What is the significance of the time horizon?
    • The time horizon determines the period over which SCC is calculated, influencing its magnitude.
  7. What are the implications of a higher SCC?
    • A higher SCC indicates a need for more urgent climate action and higher carbon pricing.
  8. How can individuals reduce the SCC?
    • Reducing carbon emissions through energy-efficient practices and renewable energy sources can help lower the SCC.
  9. Are there international standards for calculating SCC?
    • Different countries may use varying methodologies, but efforts are being made to harmonize calculations.
  10. Is the SCC subject to change?
    • Yes, as our understanding of climate science and economic impacts evolves, SCC estimates may be updated.

Conclusion: The Social Cost of Carbon is a vital tool for understanding the environmental and economic consequences of carbon emissions. By using this calculator, individuals and policymakers can make informed decisions to mitigate climate change and reduce the societal cost of carbon. Accurate SCC calculations are instrumental in creating a sustainable and environmentally responsible future.
