In regard to internal carbon pricing mechanisms to support decision-making concerning the impacts, risks and opportunities of climate change, Cellnex has not yet established a specific strategy. A study was conducted to assess different Internal Carbon Pricing (ICP) options for the company, yielding a preliminary proposal for implementing the Internal Carbon Rate. The fixed price of the Internal Carbon Rate was determined by considering the impacts of Cellnex’s operations. In 2022, Cellnex developed a pilot project for the application of this internal rate to the activities of IT suppliers, corresponding to Scopes 3.1 and 3.2 (procurement) of the carbon footprint. However, the result was not satisfactory as comparability between supplier data was not possible due to the low maturity of the suppliers in terms of their emissions reporting. To prepare for the future implementation of an internal carbon price, in 2024 Cellnex has been working on strengthening Scope 3 emissions measurement initiatives through supplier participation in CDP Supply Chain and ESG clauses in contracts with third parties. In 2025, it is expected to work on a Shadow Carbon Price mechanism to quantify the risks and opportunities of CO2 emissions in the purchasing process, supporting decision-making.
