Carbon Footprint of Discord
IdleForest models one hour of Discord use at about 35g of CO2.
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.

How this Discord estimate is built
IdleForest models Discord as a mixed social and communication app. The 35gCO2e/hour figure is a directional blend: above lightweight text/social browsing, below full video streaming, and anchored to peer-reviewed digital-content LCA plus published internet-use and streaming benchmarks.
- Nature Communications models social media and video conferencing as separate digital-content categories with data centers, transmission networks, home networking equipment, and end-user devices in scope.
- Obringer et al. provide a peer-reviewed internet-use footprint benchmark for data processing and transmission, while Carbon Trust estimates one hour of video-on-demand streaming at about 55gCO2e in Europe.
- Discord is set at 35gCO2e/hour because a typical mixed session is lighter than full video streaming but heavier than text-only chat when voice, media previews, and screen sharing are active.
- The yearly estimate uses 35gCO2e/hour x 1.5 hours/day x 365 / 1000 = 19.2kgCO2e/year.
- The tree estimate rounds up annual emissions divided by 20kgCO2e per tree-year, so Discord rounds to 1 tree/year in this model.
Calculation proof
How the estimate is calculated
Annual footprint formula
35g CO2e/hour x 1.5h/day x 365 / 1000 = 19.2kg CO2e/year
Tree offset formula
ceil(19.2kg CO2e / 20 kg CO2e per tree-year) = 1 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
- Autoplay, recommendation loops, and image/video-heavy feeds extend session length.
- Short-form video often behaves more like streaming than lightweight browsing.
- The device and network layer still matter even when individual interactions feel small.
Assumptions and boundaries
- The estimate reflects active social-media use over time rather than a single refresh.
- It bundles app-side, network-side, and device-side energy demand into one consumer footprint.
- The number is most useful for comparing habits and platforms.
Uncertainty note: Social-media footprints vary with media density, autoplay behavior, device, and the amount of video in the feed.
Yearly Impact Comparison
*IdleForest offsets ~200kg CO2/year on average per user.
Ways to reduce this footprint
- Disable autoplay and cut accidental scroll time where possible.
- Use smaller devices and lower brightness for casual sessions.
- Set app time limits if recommendation loops are extending usage.

More questions about Discord's carbon footprint
What is Discord's carbon footprint per hour?
IdleForest estimates a mixed hour of Discord use at about 35gCO2e. This is not a Discord vendor disclosure; it is derived from digital-content LCA, internet-use, and streaming benchmarks.
Why is Discord lower than video streaming?
Many Discord sessions are text or voice first, so the model is lower than the Carbon Trust's 55gCO2e/hour video-streaming benchmark. It still includes device, network, and server-side energy rather than treating chat as zero-impact.
