Mobile network operators (MNOs) are increasingly focusing on building energy efficient networks, as consumers and governments are becoming more focused on sustainability. As we transition to new mobile network standards the energy efficiency in terms of energy consumption per unit of traffic is improving but the overall energy consumption from the telecom sector is still rising due to factors such as increased data traffic, new infrastructure to support new standards, and increased cellular connections. 5G is more energy efficient than 4G in terms of energy consumption per unit of data but the overall energy consumption is higher. Mobile telecom operators are aiming to become net-zero between 2040 and 2050; to achieve these targets it is important for them to work on the challenge of building energy efficient 5G networks.
In this report we explore the Next Generation Mobile Network’s (NGMN’s) Green Future Networks initiative, discussing the key members of the alliance, how companies measure their carbon emissions and the ways in which mobile operators can reduce the emissions in networks. The report also provides a broad overview of the climate protection strategies and goals adopted by major telecom operators including details on sustainability targets, initiatives and approaches taken for reducing greenhouse gas (GHG) emissions.
