Summary

When comparing Reddit and WhatsApp, Reddit generates significantly more CO2 emissions per hour (25g) than WhatsApp (18g). Both applications rely on devices, networks, and server infrastructure, which all contribute to their environmental impact.

Why the gap happens

Reddit is modeled at 25g CO2 per unit, while WhatsApp is modeled at 18g, so the visible gap is 7g in the current dataset.
Both products sit in the Social category, so the difference comes from the per-product estimate and page-level methodology fields rather than a category change.
Autoplay, recommendation loops, and image/video-heavy feeds extend session length.

What to act on first

Because Reddit is higher in the current model, start there: Disable autoplay and cut accidental scroll time where possible.

Reddit is currently modeled at 7g CO2 more per unit of use than WhatsApp.
