Roskill expects only 3.2% reduction in shipping emissions of spodumene concentrate by 2030; order of magnitude below IMO ambition

Green Car Congress

Shipping emissions form a significant part of the commodity supply chain’s carbon footprint, particularly for those commodities reliant on the mass transport of low-grade ores and concentrates. This highlights the benefits increased economies of scale would have on this part of the spodumene supply chain, Roskill said.
