Estimating Emissions from Degradation by Logging  Estimating the total C emissions and CO2 emissions from selective logging, with use of the following formula:  Vol= Total volume of timber extracted through selective logging activities per year  ELE= Extracted Log Emissions (t C/m 3 )  LTP= Proportion of log carbon going into Long Term Wood Products (%)  LDF= Logging Damage Factor (t C/m 3 )  LIF= Logging Infrastructure Factor (t C/m 3 )
