Carbon footprint hub
Digital Carbon Footprint of Apps: Calculators and Comparisons
Compare the estimated carbon footprint of popular apps, AI tools, streaming platforms, games, browsers, and social networks. Use the calculators to estimate CO2 per hour, yearly emissions, and trees needed to offset your digital habits.
How to use this guide
How app carbon footprint estimates work
What counts in a digital carbon footprint
App emissions can come from device energy, network data transfer, server processing, cloud storage, media delivery, and how long a session lasts. That is why video, AI, gaming, messaging, and browsing pages use different assumptions.
Use app calculators for specific estimates
Each app page turns a modeled CO2-per-hour estimate into weekly use, yearly emissions, and trees needed to offset the habit. Start here, then open pages like Discord carbon footprint, ChatGPT carbon footprint, Netflix carbon footprint, or TikTok carbon footprint.
Compare apps, categories, and tradeoffs
The hub groups AI, streaming, gaming, social media, work, browsing, and crypto pages so you can compare similar tools side by side instead of treating every digital habit as the same.

Best places to start
ChatGPT
ChatGPT's carbon footprint comes from every request, response, and supporting system behind the model. If you're asking how much CO2 ChatGPT produces, the answer depends on model size, response length, and how often you use it.
Discord
Discord has not published an official per-hour carbon footprint, so this page models Discord from published digital-content research. The estimate depends on the mix of text chat, voice rooms, video calls, screen sharing, and always-open desktop sessions.
Every photo, Reel, and Story on Instagram requires server storage and global network transmission, contributing to your personal digital footprint.
TikTok
TikTok's footprint comes from video delivery, device energy use, and the time people spend scrolling through high-definition short-form video.
YouTube
YouTube's carbon footprint adds up across content processing, global delivery networks, and the device used for playback. If you're comparing YouTube emissions per hour or the CO2 cost of video streaming, watch time, resolution, and autoplay matter most.
Netflix
Netflix's carbon footprint comes from data centers, content delivery networks, and the device you watch on. If you're comparing Netflix emissions per hour, the biggest drivers are watch time, video quality, and whether you stream on a phone, laptop, TV, or console.
Zoom
A Zoom call can avoid travel emissions, but it still has a carbon footprint of its own. If you're estimating Zoom call emissions, the main factors are meeting length, participant count, camera use, and the device each person joins from.
Slack
Slack is mostly a text and notification workflow, but its footprint rises with long active desktop sessions, file previews, huddles, clips, and video calls.
WhatsApp is usually lighter than video-first social apps because much of the activity is text and voice messaging, but photos, videos, backups, calls, and group activity still use devices, networks, and servers.
