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 document mentions that climate change management is led by the Chief Strategy Officer, who reports directly to the CEO, indicating integration into the company's strategy. The company is committed to periodically reviewing its Environment and Climate Change Policy, which is communicated effectively across the organisation and made available to stakeholders to promote transparency. Oversight of the climate change strategy is carried out by the Nominations, Remuneration and Sustainability Committee (NRSC), which reports to the Board of Directors.

The document does not explicitly state whether the transition plan for climate change mitigation has been approved by the administrative, management, and supervisory bodies.

Since its foundation, Cellnex has been working to limit the effects of climate change and to contribute to the decarbonisation of the economy. The company is aware that it is essential to go much further. If no drastic actions are taken to limit the temperature increase to 1.5°C by 2030, the potentially catastrophic consequences of runaway climate change for both people and the natural systems that sustain them could be unavoidable. Therefore, taking action without delay is imperative.

Cellnex is committed to protecting the environment as part of its company strategy, formalizing this through its Environment and Climate Change Policy. This policy applies to all of the Company's geographies and sets out basic principles for action in its own operations, with its suppliers and business partners, and in interactions with stakeholders in the value chain. In 2024, the Board of Directors approved an update to this Policy to incorporate Cellnex Net-Zero commitment, the TNFD as a framework on natural capital and biodiversity issues, and updates to other legal frameworks (CSRD, CSDDD, and others).

The Environment & Climate Change Policy includes principles for action such as minimizing greenhouse gas emissions to achieve Net-Zero target, protecting biodiversity, ensuring responsible and circular use of resources, and strengthening environmental stewardship. It extends commitments to environmental management, mitigation, and adaptation to climate change and protection of natural capital in the value chain.

Cellnex has established commitments and lines of action to address climate change mitigation and adaptation, protection of natural capital, and environmental management. This includes the establishment and monitoring of GHG emission reduction targets, deployment of a decarbonisation plan, disclosure of carbon footprint results, analysis of infrastructure vulnerability to climate change, and promotion of infrastructure resilience through climate change adaptation measures.

Cellnex's Net-Zero strategy is structured around seven key pillars: 1. Science-based reduction targets, 2. Energy transition, 3. Value chain engagement, 4. Circular economy practices, 5. Sustainable mobility, 6. Neutralisation of residual emissions, 7. Transparency and governance. The company plans to address residual emissions by financing high-quality carbon reduction and removal projects outside its value chain, aiming to foster positive impacts on ecosystems and local communities. Cellnex also aims to verify its Net-Zero target through the Science Based Targets initiative (SBTi). Key components of the reduction strategy include leveraging renewable energy through the purchase of Guarantees of Origin (GoOs) and expanding solar panel deployments.

The Energy Transition Plan includes several adaptation solutions: Energy 4.0 leverages advanced technologies to create a smart ecosystem for energy consumption traceability. Green energy sourcing ensures 100% of electricity consumed at sites comes from renewable sources by 2025. Energy efficiency improvements are made by increasing passive equipment efficiency and optimizing customer equipment. Self-generation involves expanding on-site renewable energy solutions such as solar panels and hydrogen batteries. The anticipated financial effects from material physical and transition risks are not explicitly quantified in the provided text.

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
• Suppliers Further information is available in the 2023 Environment and Climate Change Report.
