Siyag unfccc methods ws oct 2011

  1. 1. Standards Setting Unit, SDM Programme Panna Siyag Accounting approach in A/R CDM project activities FAO, Rome 27 October 2011
  2. 2. A/R CDM standards: Overview of features  Ex ante (approx) vs. ex post estimation  Project emissions (limited to use of fire)  Leakage (limited to clearance of forested areas)  Uncertainties (“precise or conservative” approach) – 90/10 precision in sampling  Monitoring costs (“orders of magnitude” approach – pools/ components)  herbaceous << shrubs << tree  Change estimation approach – indirect (gain-loss method) vs direct (stock change method)  Overall basis – IPCC (plus other published literature)
  3. 3. Changes in carbon pools: Estimation approaches Pool Estim. in BSL Estim. in PROJ Aboveground biomass (excl. herbaceous b.) -indirect (ratio) -sample measurement -sample measurement Belowground biomass -indirect (ratio) -indirect (ratio) Dead wood -insignificant -indirect (ratio) -sample measurement Litter -insignificant -indirect (ratio) -sample measurement Soil organic carbon (SOC) -default value (IPCC) -indirect (IPCC factors)
  4. 4. A/R CDM standards: Research needs  Accurate/cost-effective tree allometric (biomass) equations – or other methods  More precise factors / ratios  e.g. shrub/forest biomass ratio; DW/AGB, LT/AGB ratios  Significance, and methods of cost-effective estimation, of (i) project emissions (ii) C stocks in herbaceous biomass  Significance of upstream / downstream effects  e.g. manufacture of fertilizers used (negative, upstream); biomass harvested replaces more emission-intensive materials (positive, downstream)  Approaches to addressing leakage  e.g. intangible shift of demand to TOF; or, TOF increases in competition with project
