Direct and indirect GHG (greenhouse gas) emissions
The trend of direct and indirect greenhouse gas emissions over the past years, in line with the GHG protocol, is provided below.
(1) The methodology and sources considered for calculating greenhouse gas emissions (Scope 1, 2, 3) are detailed in the following paragraph. The values for 2018 and 2017 were modified by adding the new calculation categories introduced in 2019. The Scope 2 emissions for electricity purchased from the grid were recalculated due to the expansion of the calculation basis. Regarding the year-over-year data comparison and the relative sums, the figures shown in the table regarding year-over-year data comparison and subset additions are calculated considering decimal digits that may not be disclosed in the table.
(2) For all combustion processes from fossil sources, the production of N2O (GWP = 265) and CH4 (GWP = 28) expressed in CO2 equivalent are included. These values, not present in the 2017 and 2018 reporting, were recalculated for the previous two years. The calculation of the other activities also includes CO2 equivalent emissions from the combustion of diesel fuel in the generating sets, from the fuel of the company fleet, from the fuel used in the offices for heating and canteens, fluorinated gases and ODS, SF6 and NF3.
(3) The values do not include the emissions from technical losses of the Enel distribution grid, which were calculated only as location based.
(4) Avoided emissions are calculated as the sum of the emissions avoided in the different countries where Enel is present. The resulting value is the product of the generation of electricity obtained from a renewable or nuclear sources and the specific CO2 emissions from the thermoelectric generation of the country in which Enel is present.
The GHG inventory statements were audited by DNV GL, one of the main certification entities world-wide, with a reasonable level of certainty for Scope 1, Scope 2 and Scope 3 emissions, as limited to the sale of natural gas, and with a limited level of certainty for the other Scope 3 emissions included within the scope of application of the inventory. The audit was conducted according to Standard ISO 40643 for the compliance of greenhouse gas (GHG) inventories with the WBCSD/WRI Corporate Accounting and Reporting Standard (GHG Protocol).
CO2 reduction targets
Financial, operational and environmental metrics
(1) The 2018 data regarding EBITDA and Capex were reclassified due to a change to the calculation methodology for those metrics in comparison to low-carbon products and services.
(2) The “low-carbon products, services and technologies” category considers the Enel Green Power, Infrastructure and Networks, Enel X and Market Business Lines (excluding the sale of gas).
(3) The value was calculated considering the impact of the financial instruments, which include sustainability criteria for the entire gross debt.
(1) Does not include managed capacity, equal to 3.7 GW in 2019 and 4.2 GW in 2018.
(2) Does not include generation from managed capacity, equal to 10.2 TWh in 2019 and 9.7 TWh in 2018.
(3) The % was calculated based on new methodology that does not consider the Italian oil & gas plants in the decommissioning phase/considered marginal. The values do not include consumption and generation for the cogeneration related to the Russian thermoelectric park. The average efficiency value is calculated based on the plants in the park and weighed based on generation values.
The following table shows the main operational targets included in the 2020-2022 Strategic Plan that reflect Enel’s role in the fight against climate change along the entire electricity value chain, in addition to the greenhouse gas emissions reduction targets as described in the previous section.
(1) Does not include managed capacity, equal to 5.6 GW in 2022.
(2) Does not include generation from managed capacity.
Furthermore, the following assumptions were deﬁned:
- EBITDA incidence for low-carbon products, services and technologies equal to approximately 91% in 2022;
- Capex incidence for low-carbon products, services and technologies on the total more than 90% in 2020 -2022;
- incidence of sustainable ﬁnancial mechanisms equal to approximately 43% in 2022.
