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.
