Digital Carbon Footprint
A digital carbon footprint is the emissions impact created by the devices, networks, and data centers behind your online activity. Use this guide to connect that broad idea to everyday browsing, work, and social habits.
The cloud is physical infrastructure
Every search, feed refresh, file sync, and meeting still depends on servers, networking equipment, and electricity somewhere in the background.
Habits matter more than isolated clicks
A single digital action is often tiny, but repeated patterns such as long meetings, autoplay feeds, and browser-heavy workdays add up over time.

Google Meet
Google Meet video calls rely on efficient Google infrastructure, but the combined energy use of meetings still adds up quickly. If you're comparing Google Meet with Zoom or estimating video meeting CO2, the biggest factors are call length, participant count, cameras on, and device choice.
