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.
