The carbon-neutral mobile network

Tackling the holistic energy challenge

As much as 5G networks will inevitably carry more data traffic than prior generations, the energy challenge for telecoms operators in reducing their carbon footprint is holistic across all facets of the business. This implies the need for a cross-cutting energy strategy.

Notions of 'green 5G' or 'sustainable 5G', while attractive, do not speak to the full range of actions underway. For example, more energy-efficient network kit is as applicable to 4G as 5G networks. Similarly, sunsetting 2G and 3G networks – which are far less efficient – will help. Renewables are perhaps the most potent underlying change driver, specifically solar and wind to complement hydro.
