Your background footprint
You don't have to use AI to have a data footprint. Rewards programs, apps, and connected cars send marketing email, sell ads against your purchase history, and pass your data to brokers all year, whether you open them or not. Each step runs on servers and networks that use electricity.
52 organizations profiled from public sources: 40 companies that run rewards programs, apps, and connected services people use, such as stores, restaurants, gas stations, phone carriers, and carmakers, and 12 data brokers, which hold data about people who never signed up with them. Each page estimates the emissions for one person, then lists what the organization collects, what it does with the data, and enforcement and litigation, with sources.
Data current as of 2026-09-25; statuses change. Scores use the data practices rubric, 0 to 15.
