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 targets set by Cellnex 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. Specific strategies include sourcing of renewable electricity, reduction of scope 1 and 2 GHG emissions and scope 3 GHG emissions from fuel and energy-related activities, reduction of absolute scope 3 GHG emissions from purchased goods and services and capital goods, and reduction of the carbon footprint: scope 1, 2 and 3 (Carbon neutral).
