A tool to compute
ecosystem carbon


Adding or conserving ecosystem carbon can be an extremely cost-efficient way to mitigate climate change.


How much ecosystem carbon is there when land uses are changing?

When land uses are not changing, ecosystem carbon can be computed by multiplying area with carbon density. But how can we calculate ecosystem carbon in dynamic landscapes where there are changes not only in land use, but also in carbon densities due to a legacy of past uses?

  • Define land-use classes
  • Predict future land-use changes
  • Set carbon equilibrium densities (e.g. tons per hectare)
  • Input transition speeds based on local or global data
  • Include uncertainty

Use CarboScen to compute future ecosystem carbon for a simulated land-use scenario
