Letter to the Stakeholders

In 2022, we saw significant social, geopolitical and economic events, which made the reference context very challenging.

During these particular events, Acea sought to accelerate its sustainable development even further by implementing major ESG initiatives.

Our definition of sustainable success does not overlook the preservation of the natural environment, the increased ability to adapt to and predict the climate change already happening, and the commitment to mitigating its future effects, nor does it overlook social inclusivity. These basic principles will guide the Group's future developments.

Relations with the Environment

Dealing with vital resources such as water and energy requires the management of complex infrastructures - networks and plants - in the territories and has important impacts on the community. We are committed to ensuring that these impacts become growth opportunities for us and our stakeholders.
