(distribution, moving fuel, extracting coal, property management and also the electricity purchased from the grid from hydroelectric plant, is the product of the electricity consumption, including grid losses, multiplied by the respective weighted specific emission coefficients of the whole generation mix of the countries where the Enel Group operates (source: Enerdata - https://www.enerdata.net/).“Scope 3”: the estimate of indirect emissions of CO2 relating to 2017 and arising from the transport of coal by sea is calculated starting from the quantity transported (equivalent to 66.6% of the total coal used), taking into consideration Panamax ships with a 67,600 ton capacity, which cover average distances of 700 nautical miles in 22 days, consuming 35 tons of oil a day, and an emission coefficient of 3.2 kg of CO2 per liter of oil consumed, considering also three days stopover for unloading, to which consumption of 5 tons of oil is associated.
