This report includes, apart from information on the company’s own operations, the material impacts, risks, and opportunities associated with its value chain. This encompasses both the upstream and downstream stages, covering the direct and indirect business relationships of the entity. Information on the value chain is included based on the results of the double materiality assessment, limited to those parts of the value chain where sustainability issues are relevant.

In 2024, Cellnex updated its sustainability reporting methodologies to align with the CSRD requirements, introducing several key refinements. Metrics and methodologies were also redefined to enhance alignment with internationally recognized frameworks, improving the precision and reliability of reported data. Comparative figures for prior periods, such as water consumption and energy use, were recalibrated according to the carbon footprint recalculation.
