Table 2 Emissions factors (EF) expressed as CO2 equivalents for the three GHG gases and the calculated combined global warming potential (GWP) expressed both per year (annual EF) and over the 30 year plantation production cycle (total EF).
From: Greenhouse gas emissions resulting from conversion of peat swamp forest to oil palm plantation
