  2. How many tonnes of C sequestered will my project deliver? TARAM has the answer! Objective: facilitate application of approved AR methodologies

  3. TARAM – Main Features • Excel-based tool – linked spreadsheets • Links to outside resources, e.g. AR meths • Internal links for further information e.g. IPCC GPG – LULUCF • Color coded cells - “yellow” is important • Color coded spreadsheets

  4. Selection of applicable AR methodology Estimated ex ante baseline GHG removals Estimated ex ante actual GHG removals Calculation of the project’s leakage Parameter values for all tree and woody species in baseline and project scenario 6 worksheets for different baseline strata 6 worksheets for different stand models Overlay of baseline strata and stand models Estimated volume of tCERs or lCERs Optional: financial analysis of the activity Amount of ha per stratum to be afforested / reforested each year Chart shows removals and associated flow of CERs Applies only in situations with pre-project AR activities in the baseline IPCC GPG-LULUCF default values Wood densities of tropical tree species Distances to and from the AR sites – input for leakage estimation

  5. = $ So far, foresters have been concerned about the trunk volume. This good, because data about this key variable for estimating forest carbon should be available almost everywhere...

  6. j BEF = Biomass Expansion Factor j j , t j R = Root to Shoot Ratio j = Species dependent t = Time dependent Key Variables D = Wood Density V = Trunk volume Above-Ground Biomass (AGB) = V*BEF*D Below-ground Biomass = ABG*R About half of the biomass is Carbon

  7. Volume / Age Relationship Volume / age relationship represented bycumulative growth curve (CGC)- sigmoid for trees - • Juvenile phase (youth) - accelerating rate of growth • Full vigor phase - constant rate of growth • Senescent phase - decelerating rate of growth

  8. Cumulative Growth Curve m3 ha-1 Cumulative growth curve Decelerating rate of growth Fast, constant rate of growth Accelerating rate of growth Time

  9. Forest Stand Management Cumulative growth curve m3 ha-1 Standing Volume Time

  10. Increment / Age Relationship • Current annual increment (CAI): increment over one year at any stage in the tree's history • Mean Annual Increment (MAI): mean annual increment over the whole period from origin to a specific age

  11. m3 ha-1 Cumulative growth curve = Total production Standing Volume Time m3 ha-1 yr-1 Current Annual Increment Mean Annual Increment Time

  12. m3 ha-1 Method 2 Standing Volume Stand volume Thinning and harvest volume Time m3 ha-1 yr-1 Method 1 Current Annual Increment CAI Thinning and harvest volume Time
