Corporate Environmental Footprint (CEF)

Iberdrola, first organisation to receive the AENOR certificate for our Environmental Footprint

Corporate social responsibility Renewable energy

True to our commitment to transparency, every year we publish our Ecological Footprint (CEF), a summary of the Group's environmental performance. External and independent verification by AENOR accredits that we have calculated and identified all the environmental impacts derived from our activities in all the countries in which we are present, with the aim of improving and reducing them.

The Corporate Environmental Footprint (CEF) is defined as a multi-criteria measure of the environmental performance of an organisation that provides goods or services, with the perspective of the whole life cycle, i.e. considering not only direct impacts but also indirect impacts on which we have influence, for example through our suppliers. The overall objective of an CEF is to seek to reduce the environmental impact derived from the organisation's activities.
