This document is a progress report detailing AT&T's Gigaton Goal, which aims to enable customers to reduce greenhouse gas (GHG) emissions by one gigaton (1 billion metric tons) through the use of AT&T connectivity by 2035. The report outlines the cumulative impact of emissions reduction from 2018 to 2024, with a total of 227.2 million metric tons of CO2e reduced by the end of 2024. It identifies nine key impact areas where AT&T connectivity contributes to emissions reduction, including the Modern Workplace, Transportation, and Smart Cities. The report also provides a summary of carbon abatement factors for various activities associated with each impact area, detailing the average emissions reduction possible when using AT&T-enabled solutions. Additionally, the methodology for calculating abatement factors and emissions avoidance is discussed, referencing various data sources and assumptions used in the calculations. This report serves as an annual update on AT&T's progress towards its environmental goals.
