Major improvements uncertainties

• Monte carlo analysis on carbon stock calculation
  (inventories and BEF)
• Sensibility analysis of the models
• Result - 20 CV (to be confirmed)

9
Major improvements

• Smallest polygon considered in the spatially
  explicit inventories
• Unique soil association and land use type
• Climate stratification

Conclusions for Belgium

• Next submission all pools will be covered
  revision of BEF
• Uncertainties estimation for biomass C (Monte
  carlo sensibility analysis) and soil C (error
  propagation)
• Remaining issues
• Land-use change (mainly due to agricultural land
  converted to other land-use in Belgium)
  differences between areas under geographical
  definition (eg CORINE) and activity data
  (national statistics). Study ongoing.
• Article 3.4. not yet decided
• HWP no activity data
• Long term projections expert judgment
