NGMN publishes new reporting guidance to accelerate carbon emissions reductions in mobile industry

Düsseldorf, Germany, 21 May 2025 – The Next Generation Mobile Networks Alliance (NGMN) today released new guidance to support more effective carbon emissions reduction in the mobile industry through improved reporting practices and stronger collaboration. 

 

The publication, “Green Future Networks: Environmental Sustainability and Reporting”, offers practical recommendations for addressing Scope 3 emissions – those generated across the broader value chain – which represent approximately 90% of total emissions for mobile network operators (MNOs)1.
 

NGMN advocates for a shift toward using primary (unit-based) emissions factors rather than traditional financial (price-based) ones to enhance reporting accuracy. The guidance also emphasises the need for greater collaboration and industry-wide alignment of calculation methods. 

 

“Tackling Scope 3 emissions is one of the greatest challenges for our industry — and it can only be done through stronger collaboration across the value chain,” said Laurent Leboucher, Chairman of the NGMN Alliance Board and Orange Group CTO and EVP Networks. “This new guidance marks an important step toward more accurate, transparent reporting and provides a clear path for the industry to prioritise meaningful carbon reduction.” 

 

The publication assesses the current state of sustainability reporting across MNO value chains and outlines challenges faced by both operators and infrastructure suppliers in addressing Scope 3 greenhouse gas emissions — those originating from the value chain rather than sources directly controlled by the companies. It highlights key issues such as data availability, accuracy, and inconsistent estimation approaches, all of which impact emissions reporting. 

 

The guidance calls for emissions reporting based on unit-based emission factors – calculated by multiplying a specific factor per unit of product or category by the number of units used – which provide greater accuracy than spend-based methods. This shift will require closer collaboration among value chain partners to improve data sharing and align calculation methods. 

 

 “Reducing emissions across the value chain requires close collaboration with our supply chain partners to identify the main sources of emissions,” said Saima Ansari, GFN Project Lead and CR Segment Lead, Technology & Innovation at Deutsche Telekom. “By working together to ensure we all have access to accurate data on emissions factors and energy mix, we can better assess our carbon footprints and take targeted action to meet our reduction goals.” 

 

The publication also reviews key standards and regulatory frameworks, explores their interrelationships, and recommends that stakeholders stay aligned with and actively contribute to the evolving regulatory landscape. 

 

“Since 2021, our Green Future Networks programme has brought together operators, vendors and academia from around the world to collaborate, share insights and co-develop strategic guidance on one of the most critical issues facing our industry,” said Anita Doehler, CEO of the NGMN Alliance. “We are proud of our members’ continued commitment to advancing sustainability.”

Green Future Networks- Metering in Virtualised RAN Infrastructure

New Recommendations for Measuring Energy Consumption in Virtualized Networks

Dusseldorf Germany, 04 April 2024.

Today’s publication by the Next Generation Mobile Networks Alliance (NGMN), titled ‘Green Future Networks: Metering in Virtualised RAN Infrastructure,’ offers key recommendations to the industry regarding the measurement of energy consumption in virtualised RAN networks. The publication was jointly developed by the NGMN membership, including Mobile Network Operators (MNOs), vendors and research institutes.

“Addressing the challenge of managing and minimising energy consumption is paramount within our industry,” remarked Arash Ashouriha, Chairman of the NGMN Alliance Board and SVP Group Technology at Deutsche Telekom. “Through this publication, the NGMN Alliance delivers vital recommendations for industry standards, facilitating more precise and real-time estimations of energy consumed by virtualised or cloud-native network functions.”

“Sustainability is a considerable concern for MNOs and their customers,” emphasised Laurent Leboucher, Member of the NGMN Alliance Board and Group CTO at Orange. “Accurate measurement of energy usage in our networks and associated carbon emissions is essential. This publication marks a crucial stride towards fostering greater transparency in energy consumption within virtualised infrastructure.”

This latest NGMN publication highlights the necessity of enhancing current 3GPP Virtual Network Function (VNF) / Cloud Network Function (CNF) energy consumption estimation frameworks for more precise measurement of energy consumption by VNF/CNF on shared IT/Cloud infrastructure. The publication offers several recommendations to Standards Development Organizations (SDOs) to accelerate the development of enhanced frameworks.

Additionally, the publication underscores the potential of utilizing Redfish® by DMTF (Distributed Management Task Force) along with open-source tools like Kepler (Kubernetes-based Efficient Power Level Exporter) and Prometheus. This combination enables MNOs to perform network-wide, real-time, and accurate estimations of IT-infrastructure performance and power consumption. These estimations are regarded as accurate enough to be effectively considered as ‘measurements’.

The publication emphasises that operating models will influence MNOs’ ability to manage the performance and energy consumption of vRAN functions. It suggests that APIs between Cloud Service Providers (CSPs) and MNOs may need to replace standardised FCAPS (Fault, Configuration, Accounting, Performance, and Security) interfaces if not exposed by the CSP.

“Bringing together the industry to tackle our shared challenges, unlocking opportunities and providing crucial guidance to the industry is NGMN’s core mission,” stated Anita Doehler, CEO at NGMN Alliance. “This publication further advances the industry’s capacity to deploy disaggregated, virtualized and cloud-native architectures, all while effectively managing energy consumption and environmental impact.”
