Cellnex has translated its climate commitment into a comprehensive corporate strategy aimed at reducing and neutralising its emissions. This strategy is underpinned by specific medium- and long-term objectives, framed in seven pillars that will enable the company to achieve its Net-Zero target in 2050. These seven key pillars are: 1. Science-based reduction targets: addressing the key scopes of Cellnex’s carbon footprint. 2. Energy transition: 100% renewable energy by 2025, efficiency, smart metering and self-generation. 3. Value chain: engagement and emission reduction targets. 4. Circular economy: green sourcing, eco-design and eco-strategies. 5. Sustainable mobility: transition to green fleets and travel and mobility plans. 6. Neutralisation of residual emissions: offsetting. 7. Transparency and governance: carbon management at the core of the company’s activity. During 2024, Cellnex has worked on modelling the Net-Zero target to extend the scope of existing initiatives up to this year by identifying additional emission reduction levers. To this purpose, the company has carried out an analysis of the current situation and future positioning, analysing the existing organisation, policies and strategy. This analysis is based on external drivers and stoppers, internal gears and reduction levers: 1. Internal changes: changes in a Cellnex activity (business growth, business model change, etc.) 2. External drivers and stoppers: factors that are largely beyond the control of the company (grid decarbonisation, network evolution, etc.) 3. Reduction levers: Cellnex’s initiatives to reduce emissions.

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.
