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.

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.
