El desempeño de Enel en la lucha contra el cambio climático

En 2020, la huella de carbono (carbon footprint) total de Enel fue de 97,9 mln tCO2eq (26% menos que en 2019), principalmente debido a una menor producción de energía eléctrica a partir de combustibles fósiles, dividida de la siguiente manera:

> Alcance 1: 45,3 mln tCO2eq (reducción de 35,3% con respecto a 2019), lo que representa el 46% de las emisiones GEI totales. El 99% de estas emisiones son producidas por la actividad termoeléctrica. El porcentaje de emisiones relacionadas con el Régimen de Comercio de Derechos de Emisión de la Unión Europea (RCDE UE) es igual al 53% del total del Alcance 1 (en comparación con el 49,5% de 2019).

> Alcance 2: 5,0 mln tCO2eq (reducción de 7% con respecto a 2019), lo que representa el 5% del total de las emisiones GEI. Además, el 71% de las emisiones de Alcance 2 están relacionadas con pérdidas técnicas en las redes de distribución.

> Alcance 3: 47,7 mln tCO2eq (reducción de 16% con respecto a 2019), lo que representa el 49% del total de las emisiones GEI. El uso de bienes vendidos (mercado minorista de la electricidad y gas) representó el 98% de la huella de estas emisiones.
