GREENHOUSE GAS EMISSIONS

The current scope of the Sustainability Report is for Paladin’s two mine sites LHM and KM, therefore the approach for the reporting of emissions is operational control. The efficient use of energy is central to reducing greenhouse gas emissions, as well as reducing the cost to Paladin associated with fuel and other energy uses. Energy usage at LHM was slightly greater than for the previous year due to a greater amount of ore being processed. This resulted in greater greenhouse gas (GHG) emissions at LHM in terms of CO2 equivalent for Scope 1 direct site-generated GHG emissions and also for Scope 2 indirect GHG emissions from purchased electricity.

Total direct and indirect greenhouse gas emissions at LHM and KM are shown in Table 10.

During the reporting period, indirect emissions from the purchase of off-site power generation contributed to around 44.1% of the total GHG emissions at LHM which was slightly lower than the previous year at 46%. There was a slight decrease in the total (Scope 1 and Scope 2) CO2 equivalent generated per tonne of ore processed from 0.041 for the previous year to 0.039 for this reporting period.

The tonnes of CO2 equivalent generated at KM were lower than those generated in the previous year as there continued to be no mining or ore processing conducted. Diesel use for on-site power generation at KM constituted approximately 88 % of the total GHG emissions during the reporting period.
