英文摘要: The objective of this study is to investigate greenhouse gas mitigation pathways for the iron, gold, and potash mining sectors in Canada. These sectors have not widely accepted the available cleaner production strategies and so there is potential to reduce greenhouse gas emissions. It is important to fully realize this potential as soon as possible to support efforts to limit global warming. We conducted cost-benefit analyses of implementable greenhouse gas reduction strategies in order to inform policy and industry. Twenty-four greenhouse gas emission reduction options not yet implemented in Canada were identified following a review of current processes and operations at 102 mine sites. We developed a novel model to assess these options, integrating technology diffusion rates and long-term energy-environmental modelling. We found that the maximum greenhouse gas reduction potential can be realized through simultaneously implementing fifteen technology changes, eliminating 21 million tonnes of CO2 eq. by 2050. Furthermore, we showed that the marginal greenhouse gas abatement costs are negative, indicating that the industry would also achieve long-term cost savings if these changes were pursued. Implementing high pressure grinding rolls in iron mining and electric and diesel hybrid haul trucks in underground gold mining and potash mining have the most favorable greenhouse gas abatement costs of −4120, −3096, −701 $/tonne, respectively. These results show that these technology changes should be pursued since both environmental benefit and cost savings would be achieved. © 2019 Elsevier Ltd Citation statistics:
