We deliver digital infrastructure that supports sustainability through innovation. Our goal is to be the supplier of choice, helping customers improve ESG performance. By building agile, energy-efficient and modular platforms, we reduce hardware needs, enable smart building services and advance high-performance networking. Our ESG strategy brings product, operations and marketing teams together to embed sustainability across the business.

Colt’s on-demand NaaS platform is a cloud service that lets organisations outsource networking instead of building and maintaining their own. By applying the efficiency of cloud models to networking, we help customers cut costs, improve agility and lower the environmental impact of their IT. Designed with sustainability at its core, the platform uses advanced software to give users efficient, intent-based control of their network.

Colt leads in using Universal Customer Premise Equipment (uCPE), which combines routing, firewalls and edge computing on one device. Paired with SD WAN, NFV and technologies like SASE, uCPE cuts hardware needs at customer sites, lowering energy use and complexity while boosting security and agility to adopt new solutions without replacing equipment.

We piloted an award-winning Smart Buildings programme, an AI-driven sustainable building management platform that monitors, controls and improves the performance of a building’s core systems (e.g., heating, ventilation and air conditioning), thereby reducing energy consumption and CO2 emissions.

We worked with Communications Infrastructure Networks (CIN) to build Street Edge, an edge compute pilot using Intel® technology. It provides fibre connectivity, internet access, cloud-native edge servers for tenant applications, and space and power for up to three 4G/5G base stations. By processing data near the source, edge computing reduces the energy used in long-distance transmission.

The application of virtual Customer Premises Equipment (vCPE) and edge driven networks (EDN) also offers significant advantages over traditional CPE, such as reduced hardware requirements, reducing power, cooling and environmental impact.
