The estimated greenhouse gas emissions were 11.9 kg CO 2 e for mining and processing 1 tonne of iron ore. The embodied energy values were 153 MJ/t ore for iron ore. The results showed that loading and hauling made the largest contributions (approximately 50%) to the total greenhouse gas emissions from the mining and processing of iron ore.
