Continuous and systematic reporting of forest carbon impacts

Reporting of quantified climate impacts is becoming a core figure in companies’ annual sustainability reporting frameworks. For forest investors, these figures are asked more often than not in parallel with financial performance parameters. To serve this need, Simosol’s carbon accounting service provides a solution for systematic, transparent, and comprehensive reporting of annual carbon impacts from forests and forestry activities.


System components of the carbon accounting report

The key components included in the carbon accounting system are:

  1. Standing stock biomass
  2. Soil organic carbon stock
  3. Harvested wood products
  4. Operational emissions
  5. Substitution impact of the wood products

Depending on the applied reporting framework and the included system components, the results are delivered in a format and structure that serves best the needs of the client. For example, while the net annual change in the standing stock biomass and soil organic carbon stocks might be the core metric for a forest owner, estimation of downstream impacts can be automatically included to capture also indirect impacts of the applied forest management activities as a whole.
