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.
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.
