This Sustainability Report aims to provide transparent, reliable and balanced information on those matters identified as the most relevant for Red Eléctrica and its stakeholders in 2017 in the field of sustainability.

For the drafting of this report, the GRI Standards, published in October 2016, have been used for the first time. The GRI Sustainability Reporting Standards have superseded the GRI G4 Guidelines that were used for the drafting of Red Eléctrica’s Corporate Responsibility Reports for the years 2014, 2015 and 2016.
