PalmGHGPalm products greenhouse gas accounting toolDeveloped by WS1 based on Chase & Henson (2010)Based on LCA approach (ISO 14044) and a review of guidelines/toolsGoal & scope• To identify GHG emission hotspots and reduction opportunities• To monitor GHG emissions and to report on progress (internal)• To report for certifications (external e.g. RED, RSPO…)Need to capture the bulk of GHG emissions and carbon sequestrationAssessment at the mill level (i.e. certification unit) encompassing all plantationsNeed for flexibility:– Default data & field data as often as possible– Functional units: tCO 2 e/ha, tCO 2 e/Crude Palm Oil, tCO 2 e/MJ palm biodiesel– Physical allocations & credits for exported biomaterial or energy savingsCécile Bessou – Cirad-UPR34 LCA Food 2012 – Saint-Malo 04/10/2012 8/19
