Summary

When comparing TikTok and YouTube, TikTok generates significantly more CO2 emissions per hour (160g) than YouTube (46g). Both applications rely on devices, networks, and server infrastructure, which all contribute to their environmental impact.

Why the gap happens

Short-form feeds can extend use time through recommendation loops.
YouTube spans both long-form and short-form behavior, which changes the average energy pattern.
Playback device remains a major swing factor in both cases.

What to act on first

Reducing accidental watch time often matters more than shaving a few minutes off an intentional session.

TikTok is currently modeled at 114g CO2 more per unit of use than YouTube.
