  1. Approach = WHAT

  2. Revised IPCC 1996 Guidelines annual biomass growth versus annual harvest, including the decay of forest products and slash left during harvest Atmospheric impact = SF – DF – LM – DP Where SF = sequestration in the forest DF = decay of residues in forest LM = losses at mills during processing (burnt to waste or used for energy) DP = decay of products (related to lifetime in use or in disposal sites) Atmospheric impact = SF – DF – Harvest only if instant oxidation on leaving the forest

  3. Stock changes or Emissions Forests Products A&Re-forestation CDM Forest management Deforestation non-Kyoto countries Pre 1990 Stock change In all forests Resulting from activities since 1990 Sinks In all forests Resulting from activities since 1990 Within national boundaries = from activities within national boundaries Stock change In all products In products manufactured since 1990 In products resulting from activities since 1990 Sources from All harvested wood burning and decay Harvested wood since 1990 Harvested wood resulting from activities since 1990 Within national boundaries (incl import-export) From domestic activities (excl import-export)

  4. Simple Decay approachstocks resulting from activities Stock Source – products Sink Tier 1 – at harvest Tier 2 – default categories and lifetimes Tier 3 – improved categories and lifetimes Source – residues Time

  5. Consistency • Residues: oxidise immediately or decay • Reversal of sink when it occurs • Applicable at project or national scale • Consistent reporting and accounting • Desirable outcomes (submissions)

  6. Sustainable Forest Management Stock Sawlog regime Pulplog regime

  7. Bioenergy and Processing • Emissions remain responsibility of producer • no change to bioenergy or trade impacts • Improved inventory accuracy • Favour long rotations for sawlogs • Encourage high conversion (to product) efficiency • Sawmills least energy intensive • Opportunity for energy exporting sector • Including waste disposal sites reduces incentive for bioenergy

  8. Inventory impact annual biomass growth versus annual harvest, including the decay of forest products and slash left during harvest Production Approach: growth – harvest + hwp stock change Simple decay: growth - emissions

  9. Inventory impacts

  10. Conclusions Simple Decay approach • Described in 1996 Guidelines • Satisfies Marrakesh principles • Simple to apply (all Tiers) • National reporting and accounting • Scaleable • Promotes sustainable forest management • Promotes bioenergy Management of products is separate issue
