GSMA Scope 3 Assessment Tool
Database of Scope 3 emissions and calculation tool

Developed with leading operators, the GSMA Scope 3 Assessment tool simplifies supply chain emissions accounting for network operators. The tool comprises two components — the GSMA Supply Chain Emissions Database and the Scope 3 Emissions Calculator — offering an all-in-one platform for your Scope 3 accounting needs.
GSMA Supply Chain Emissions Database
Better data and measurement to drive climate action across supply chains.
With accurate and up-to-date emission factors for key suppliers, products, and industries, the GSMA Supply Chain Emissions Database enables network operators to improve both the coverage and accuracy of their Scope 3 inventory calculations. This, in turn, supports meaningful supply chain decarbonization efforts.
Purpose-built for telecommunications operators, this unique database streamlines Scope 3 carbon emission calculations and fosters greater alignment across the sector. The database consists of three datasets: 1) Supplier emission factors, 2) Industry average factors, and 3) Product emission factors.
Scope 3 Emissions Calculator
The Scope 3 Emissions Calculator is an Excel-based utility designed to enable network operators to assess their Scope 3 Category 1 and 2 emissions using their procurement data combined with emissions factors (EFs) from GSMA Supply Chain Emission Database, or using their own emission factors where preferred.
