Carbon Footprint of Minecraft
IdleForest models one hour of Minecraft use at about 100g of CO2.
Minecraft uses procedural generation and server-side logic that requires continuous processing power, especially when playing on large multiplayer servers.

Calculation proof
How the estimate is calculated
Annual footprint formula
100g CO2e/hour x 2h/day x 365 / 1000 = 73kg CO2e/year
Tree offset formula
ceil(73kg CO2e / 20 kg CO2e per tree-year) = 4 rounded up
Source basis: This estimate combines the app's modeled hourly footprint, usage assumption, methodology notes, and linked research sources. It is directional and should be read as a transparent consumer estimate, not a vendor emissions disclosure.
What drives this estimate most
- Gaming hardware power draw varies a lot across PCs, consoles, and in-game settings.
- Online multiplayer adds background server and data-transfer overhead.
- Session length matters because high-performance hardware pulls meaningful power continuously.
Assumptions and boundaries
- The estimate assumes active gameplay rather than a paused menu or launcher.
- It captures the combined effect of hardware energy use and online infrastructure.
- It is directional and should be read as a typical play-session estimate.
Uncertainty note: Gaming footprints can swing sharply depending on GPU load, device age, resolution, and whether play happens offline or online.
Yearly Impact Comparison
*IdleForest offsets ~200kg CO2/year on average per user.
Ways to reduce this footprint
- Lower frame rate caps and graphics settings when they do not affect the experience much.
- Use energy-efficient hardware when upgrading.
- Avoid leaving launchers and games idle in the background for long periods.

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.
