GSMA Scope 3 Assessment Tool

Database of Scope 3 emissions and calculation tool

GSMA Scope 3 Assessment 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.

Download and use it within your IT environment to ensure data security without the need to upload sensitive information to third-party applications.

Technical Annex

This document serves as a useful resource for understanding the methodologies behind the various datasets included in the Supply Chain Emissions Database.

Given the significant gaps and inconsistencies in carbon emissions disclosures at both company and product level, this “Technical Annex” has been developed to help users grasp the key data processing steps, assumptions, and calculation methods used. It also highlights features, colour legends and conventions present in the tool to aid users navigate and interpret the data more easily.

Whether you are new to the subject or an experienced practitioner, this guide will support you in making informed use of the database – quickly and confidently.
