Greenhouse Gas Emissions From Coal Mining Activities and

Fugitive coal seam gas emissions are on an average ∼43% of the sum of Scope 1 and Scope 2 emissions. Combustion of diesel represents ∼29% and purchased electricity ∼27%. This is consistent with opencut coal mines in Queensland where emissions of coal seam gas have been estimated with the default emission factors rather than from direct
