11 Sep How we build sustainable telecommunications networks

Exponential growth in data traffic and global digitalisation demand increasingly powerful network infrastructures. However, this development must move forward in harmony with environmental commitments. Across the telecommunications sector, transitioning toward planet-friendly connectivity models is a strategic and essential priority.

Integrating corporate sustainability within the technology space means transforming everything from initial infrastructure design to daily resource management, guaranteeing high-performance service with minimal environmental impact.

 

 

Integrating ESG criteria into critical infrastructure deployment 

 

Network deployment strategies aim not only to maximise coverage and minimise latency; they also structurally embed environmental, social, and governance (ESG) criteria.

Ensuring responsible development requires assessing the impact of every route before starting physical civil works. This involves prioritizing existing ducts to protect local ecosystems, using low-carbon footprint materials, and working closely with local communities to ensure critical infrastructure delivers lasting value without disturbing the natural environment.

 

 

Energy efficiency: The advantage of fibre over copper 

 

One of the fundamental pillars of building sustainable telecommunications networks lies within the transmission technology itself. The progressive replacement of legacy copper networks with fibre optics represents a major step forward in energy efficiency:

• Lower power consumption: Fibre optics transmit information using light pulses rather than electrical signals, drastically reducing the energy needed to carry massive data volumes over long distances.
• Reduced cooling requirements: Unlike traditional copper-based systems, fibre cables generate no heat along their path, reducing cooling demands at intermediate facilities.
• Durability and reduced maintenance: The resilience of dielectric materials reduces breakdowns and the need for continuous technician call-outs, lowering the operational footprint.

 

 

Neutral hosts: Shared infrastructure to reduce carbon footprint 

 

Deploying standalone, duplicated networks for each commercial operator is inefficient and unsustainable. The neutral host model delivers a collaborative solution that transforms investment dynamics across the sector.

By making a single fibre network available to multiple telecom companies, operators avoid repeatedly digging up public roads, reduce heavy machinery traffic, and optimize underground space. This shared infrastructure model directly lowers CO₂ emissions associated with civil works and efficiently accelerates connectivity delivery to underserved areas.

 

 

Circular economy and waste management in maintenance 

 

Sustainability commitments span the entire lifecycle of the infrastructure. Preventive maintenance and network node upgrades are managed under circular economy principles:

 

 

Equipment reuse and recycling 

 

Electronic components replaced during technical upgrade processes are refurbished or sent to authorized managers to recycle valuable materials.

 

 

Responsible waste management 

 

Both surplus cabling and construction materials are sorted and integrated into recovery processes, minimising the volume of waste sent to landfill.

 

 

Optimised maintenance routing 

 

Through remote network monitoring systems, engineering teams diagnose incidents in real time, avoiding unnecessary call-outs and streamlining operational transport.
