We use the following flowchart and technology matrix. (A matrix). The various processes deliver tons of steel (P1, steel mill), kWh of electricity (P2, wind power plant), m3 of concrete (P3, concrete production), and ton-km of transport (P4, rail transport). The flow chart is as follows: We use the following A matrix: You are given that the direct climate emissions from each process per unit produced are as follows: Calculate the life-cycle emissions in kgCO2 of a total final consumption of 15 ton-km of transport and 2m3 of concrete
