Enel’s performance in the fight against climate change

Enel’s performance in the fight against climate change

In 2021, Enel had a carbon footprint of 125.0 MtCO2eq (a 9% increase with respect to 2020). This was mainly due to the increased use of fossil fuels in generating electricity, which can be broken down as follows:

> Scope 1: 51.6 MtCO2eq (an increase of 13% with respect to 2020) or 41% of our total GHG emissions (99% of which come from energy production). Furthermore, 63% of the Scope 1 total is accounted for by ETS emissions (compared to 53% in 2020).

> Scope 2: 4.3 MtCO2eq (an increase of 6% with respect to 2020) or 4% of our total GHG emissions. Furthermore, 69% of our Scope 2 emissions were related to total technical network losses in the grid.

> Scope 3: 69.1 MtCO2eq (an increase of 7% with respect to 2020) or 55% of our total GHG emissions.
