Overall, diesel-powered heavy-duty trucks dominate hauling in the mining industry [4]. In mineral carbon mining, mineral loading and hauling account for 40 % of the energy used to extract and process carbon and 41 % of the GHG emissions [5]. In large surface mining, hauling can account for up to 50 %–60 % of the total operating costs [2].
