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). 

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.
