Carbon Credit Cost at 110% coverage percentage: a worked example

This scenario runs the carbon credit cost calculation on the strong side: 110% coverage percentage, with every other input held at its documented default. a sustainability or procurement lead needs to budget carbon credits or offsets

The inputs for this scenario

  • Emissions to offset: 1,800 metric tons CO2e (unchanged)
  • Credit or offset price: 22 $ / metric ton CO2e (unchanged)
  • Coverage percentage: 110 % (raised for this scenario; the documented default is 100)
  • Broker, registry, and retirement fees: 3,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable carbon credit cost = emissions to offset × credit or offset price × coverage percentage) to the inputs above produces each figure below.
  • At this operating point the engine returns 47,060 $ for total carbon credit or offset cost, the number this scenario is built around.
  • At this operating point the engine returns 26.14 $ / metric ton CO2e for credit cost per metric ton co2e.
  • At this operating point the engine returns 43,560 $ for variable carbon credit cost.
  • At this operating point the engine returns 3,500 $ for broker, registry, and retirement fees.

How this compares with the baseline

  • Against the tool's baseline example, where coverage percentage sits at 100% and the headline result is 43,100 $, this scenario comes in 9.19% above the baseline at 47,060 $.
  • Use it when budgeting an annual offset purchase, comparing offset vendors or registries, or pricing the carbon component into a product's cost. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total carbon credit or offset cost: 47,060 $ (headline result)
