Conservation of biodiversity

Our activity, respectful of biodiversity

Protecting biodiversity is an integral part of the design of our business strategy.

Aligned with the Sustainable Development Goals

SDG 14: Life below water

SDG 15: Life of terrestrial ecosystems

At Endesa we are aware of the importance of minimising the impact that industrial activity can have in the areas in which we operate. This is why we have made the protection of biodiversity a priority in the design of our business strategy.

The Biodiversity Conservation Plan is part of our Biodiversity Policy  and one of its most important and distinctive facets, since all the actions included in this plan are carried out either completely voluntarily, or go far beyond mere mandatory environmental requirements.

The main action lines of our Plan are:

  • Restoring the physical environment on our land and at our facilities to increase their capacity for hosting biodiversity.
  • Managing the factors in the natural environment surrounding our facilities that contribute to improving the habitats of certain species.
  • Recognising our natural capital and the ecosystems it is home to, their value and state of conservation.
  • Preserving native species and controlling invasive species at Endesa facilities and in the surrounding area.

The Biodiversity Conservation Plan ended 2019 with a total of 26 operational actions with the following results: 21 ongoing from previous years (5 of them were completed in 2019 and 16 will continue this year) in addition to making a start on 5 new actions. The Plan actions took place throughout Spain and Portugal and included many of our business lines.
