In particular, with reference to: renewable projects: > the quantity of COed) is determined by multiplying generation (actual or expected) by the emission factor linked to the specific thermoelectric energy generation of the country in which the plant is located (emission factors source: Enerdata - February 10, 2021 release); > in consideration of the complete allocation of the three green bonds and the volatility of production due, for example, to exceptional events such as the Covid-19 pandemic, it was decided to no longer disclose the share of production (both effective and expected) and the relative quantity of CO2 avoided attributable to the green bond, calculated as the share of green bond proceeds allocated to the project with respect to the total investment3; > for projects relating to generation plants from renewable sources, the cumulative value of actual generation and the relative CO2 avoided for all years of reporting of the green bond report is also shown (with the exception of the repowering plants whose share of generation cannot be separated from the rest of the plant); Infrastructure and Networks projects, the following indicators are also provided: > the cabling ratio, determined by the ratio between the length of the cable lines and the total length of the lines.
