Impact analysis of carbon prices on metal mining projects by block-based estimation model: Implications for cleaner production

摘要: Abstract Carbon dioxide emissions pricing is employed as an approach to mitigate climate change. To analyze the impact of carbon prices on metal mining industry, this paper presents a new block-based estimation model assess and intensity in varying prices, by employing engineering-based inputs from life cycle mineral production. Such data iron case provided test projects. The results indicate that negative profit projects more sensitive low minerals especially for underground method. On other hand, price rising facilitates mitigation emissions, lowering ratio excavated waste rocks mined-out raw ore, which varies linearly with emissions. studied decrease 39.92 kg eq per ton 21.50 kg ton, 51.02 kg 42.80 kg surface method, respectively. show it keeps increasing due rising, until boundaries are optimized based increased price.
