Summary

When comparing Fortnite and Roblox, Fortnite generates significantly more CO2 emissions per hour (150g) than Roblox (60g). Both applications rely on devices, networks, and server infrastructure, which all contribute to their environmental impact.

Why the gap happens

Fortnite is modeled at 150g CO2 per unit, while Roblox is modeled at 60g, so the visible gap is 90g in the current dataset.
Both products sit in the Gaming category, so the difference comes from the per-product estimate and page-level methodology fields rather than a category change.
This estimate combines electricity demand from gaming hardware with the always-on network and server activity needed to run online matches.
Gaming hardware power draw varies a lot across PCs, consoles, and in-game settings.

What to act on first

Because Fortnite is higher in the current model, start there: Lower frame rate caps and graphics settings when they do not affect the experience much.

Fortnite is currently modeled at 90g CO2 more per unit of use than Roblox.
