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.

The targets set by Cellnex demonstrate its commitment to reducing its environmental impact, as outlined in its business strategy. The commitment through the Science-Based Targets and the longer-term Net-Zero target involve a combination of approaches including reducing greenhouse gas (GHG) emissions, migrating energy procurement in favour of renewable and clean energy, and engaging with the supply chain. Cellnex will continue to measure and disclose its performance in relation to these objectives. Below is an overview of the most relevant climate-related metrics and targets:

• GHG emissions scopes 1, 2 and 3
• GHG intensity
• Science-based target follow-up
• Net-Zero
• Scope 1 offsetting
• Energy consumption
• Share of renewable electricity
