Sostenibilità
At Cellnex we integrate ESG (Environmental, Social and Governance) aspects into our strategy, measuring and managing the impacts we generate on society and the environment in an efficient and responsible manner.
Our value creation model, based on the Sustainaility Policy, is materialised through the 2021-2025 ESG Master Plan that sets out the roadmap to be followed.
By establishing objectives and commitments, we aspire to continue improving Cellnex’s sustainability performance while extending our commitment throughout our value chain and with our stakeholders.
Sustainability Master Plan 2030
Cellnex’s sustainability approach during the past five years has been guided by the 2021–2025 ESG Master Plan. This Plan laid the foundations for a robust sustainability strategy during a period of rapid growth, consolidation, and geographic expansion. These objectives have been successfully achieved, and today Cellnex is recognised as a sustainability leader.
As the company has matured, it is now ready to take the next step, fully embedding sustainability into its operations and business model as it looks ahead with the Sustainability Master Plan 2030.
