Environmental objectives

Decarbonising the energy mix and minimising the environmental impact of our activities are two of the main areas in which we are working to promote a sustainable business model and reduce our direct environmental footprint by 32% by 2023 (vs. 2019). The following graph summarises our environmental objectives for the coming years:

Environmental footprint

In, 2020 we reduced our footprint by 56% versus 2019. This is a significant improvement mainly due to the gradual end to coal thermal generation activity and reduced activity from generation technologies due to the unusual situation this year.

At Endesa, we are firmly committed to reducing our environmental footprint and therefore we are looking forward to tackling the goal of continuing to reduce it by another 32% by 2023.


Management of nuclear activity

We are firmly committed to the safe management of our nuclear activity, as expressed in the Nuclear Policy approved by the Board of Directors in 2011 and published on the website of the companies operating in this activity. This policy sets out the commitment to act in such a way that all nuclear activities, whether Endesa is a majority or minority shareholder, have as their main priorities: The safety and protection of workers, the public and the environment, as well as the promotion of excellence in all activities, going beyond mere compliance with legal requirements.

Environmental litigation

During 2021, there was no significant environmental violation (no final judgment with an individual fine over EUR 10,000).

In 2021, there were 44 environmental legal proceedings as a defendant and a provisioned amount of fines/penalties over EUR 10,000, totaling EUR 4,670,303.
