Mitigation of greenhouse gases released from mining activities: A review

Abstract

Climate changes that occur as a result of global warming caused by increasing amounts of greenhouse gases (GHGs) released into the atmosphere are an alarming issue. Controlling greenhouse gas emissions is critically important for the current and future status of mining activities. The mining industry is one of the significant contributors of greenhouse gases. In essence, anthropogenic greenhouse gases are emitted directly during the actual mining and indirectly released by the energy-intensive activities associated with mining equipment, ore transport, and the processing industry. Therefore, we reviewed both direct and indirect GHG emissions to analyze how mining contributes to climate change. In addition, we showed how climate change impacts mineral production. This assessment was performed using a GHG inventory model for the gases released from mines undergoing different product life cycles. We also elucidate the key issues and various research outcomes to demonstrate how the mining industry and policymakers can mitigate GHG emission from the mining sector. The review concludes with an overview of GHG release reduction and mitigation strategies.
