Suppliers
In an ever-changing world, establishing strong and lasting relationships with our suppliers is key to achieving Cellnex’s goals.
Telecommunications are changing the way we connect with the world around us. To be able to respond to the needs of the market, the collaboration of our suppliers is of vital importance.
That is why we consider our suppliers as partners, with whom we build, hand in hand, the telecom solutions of the present and the future.
Cellnex suppliers must share our values and commitment to society and the environment. We periodically evaluate the degree of sustainability of our suppliers, as well as their impact on climate change.

Procurement policy
Cellnex has created a policy setting the guidelines for the procurement process. Every player in the procurement process must be aware of it and respect its principles.
Sustainable procurement
At Cellnex, sustainability is a core element of our strategy and is fully integrated into our supply chain. We work collaboratively with our suppliers to promote responsible, ethical and environmentally sound practices, contributing together to long-term value creation and sustainable development.
Environmental, Social and Governance (ESG) criteria are embedded across the entire supplier lifecycle—from onboarding to evaluation. All suppliers are expected to comply with our Supplier Code of Conduct and relevant policies.
Through sustainable procurement, Cellnex aims to strengthen responsible supply chains, support suppliers in their ESG journey, contribute to Scope 3 emissions reduction targets, and build long-term, transparent partnerships.
We assess and monitor supplier ESG performance through recognized partners such as Carbon-disclosure Programme (CDP), ensuring transparency in areas like environmental impact and carbon footprint. For high-impact categories, suppliers may also be required to complete specific ESG questionnaires to support a comprehensive evaluation, available at this link.
ESG requirements are embedded in sourcing processes, representing 5%-15% of supplier selection criteria. Cellnex applies a structured, risk-based approach to supplier management, considering ESG, country, sector and operational risks throughout onboarding and sourcing processes. Suppliers are categorized based on their relevance and impact, and ESG requirements—including carbon reduction commitments—are embedded in key contracts. More details at this link.
We promote continuous improvement through regular performance evaluations and on-site audits focused on ESG, quality and H&S practices. Independent audits are conducted by a third-party, which also provides reporting and follow-up on non-conformities, ensuring corrective action plans are implemented where needed.
Cellnex actively supports suppliers in strengthening their ESG capabilities through initiatives such as the UN Global Compact Sustainable Suppliers Programme. In 2026, over 500 suppliers from 17 countries have been invited, helping to drive alignment with the Sustainable Development Goals and improve overall sustainability performance.
