Scope 1 Emissions
Our direct emissions (“Scope 1 emissions”) are mainly generated by losses of:
- SF6 (sulfur hexafluoride) from certain high‑voltage equipment;
- F-gases (fluorinated gases) from air‑conditioning systems;
- use of company vehicles: we have adopted a compensation policy whereby we offset CO2 emissions every year through “green” projects.
Scope 2 Emissions
Our indirect greenhouse gas emissions (“Scope 2 emissions”) from energy consumption are generated by the purchase of electricity from the grid, which is required for the operation of our plants, as well as by shared services for offices. In mid‑2016, the ESG Committee approved a project aimed at sourcing energy from renewable sources for all Group utilities, wherever technically feasible.
This has allowed us, over the years, to record a steadily increasing share of energy consumption from renewable sources.
| Year | Renewable Energy Consumption (%) |
|---|---|
| 2016 | 51% |
| 2017 | 84% |
| 2018 | 86% |
| 2019 | 89% |
| 2020 | 90% |
| 2021 | 94% |
| 2022 | 93% |
| 2023 | 96% |
| 2024 | 97% |
| 2025 | 99% |
Scope 3 Emissions
We report all 8 categories applicable to us. In 2025, the share of emissions calculated on the basis of primary data accounted for 42% of total Scope 3 emissions.
These mainly relate to:
- Product LCA (Life Cycle Assessment) for wind turbines, solar panels, and batteries
- Employee travel (e.g. flights, trains, hotels). The travel agency managing business trips is responsible for reporting these emissions using a certified methodology
- Employee commuting, assessed through a survey
- Transportation of materials, whose emissions have been offset through climate‑protection projects
In the coming years, a further reduction in intensity is expected thanks to:
- Selection of suppliers that have implemented ESG strategies, under the “Sustainable Procurement” project;
- Decarbonization projects to be implemented by the suppliers themselves.
Avoided CO2: renewables for the future of the planet
Thanks to the production of clean energy (wind and photovoltaic), ERG avoids the emission of several million tonnes of CO2 every year: in 2025, the estimated value amounted to 2,513 kt of CO2, equivalent to 5,026 London–New York flights3.
3 It is assumed that a return flight from London to New York generates approximately 1,000 kg of CO2 per passenger; assuming around 500 passengers per flight, this corresponds to 500 tonnes of CO2 per flight.
