Carbon Footprint of YouTube
IdleForest models one hour of YouTube use at about 46g of CO2.
YouTube's carbon footprint adds up across content processing, global delivery networks, and the device used for playback. If you're comparing YouTube emissions per hour or the CO2 cost of video streaming, watch time, resolution, and autoplay matter most.

How this YouTube estimate is built
This estimate reflects one hour of YouTube viewing and bundles together platform infrastructure, network delivery, and playback on a consumer device.
- YouTube behaves like other video streaming platforms, so watch quality and playback device both strongly affect the result.
- Short clips can still add up because autoplay and recommendation loops extend total viewing time.
- Watching on a phone generally uses less electricity than watching on a large TV or console.
What drives this estimate most
- Device choice can be as important as the platform itself, especially when a TV or console is involved.
- Higher resolutions typically increase both data transfer and local playback energy.
- Long sessions compound quickly because streaming is continuous rather than bursty.
Assumptions and boundaries
- The estimate represents a typical hour of use and folds together platform, network, and device overhead.
- It is designed for comparison between services rather than for a lab-grade device test.
- Actual impact changes with video quality, autoplay behavior, and playback hardware.
Uncertainty note: Streaming estimates vary with bitrate, codec efficiency, playback device, and local electricity mix, so the right interpretation is comparative rather than absolute.
Yearly Impact Comparison
*IdleForest offsets ~200kg CO2/year on average per user.
Ways to reduce this footprint
- Stream at the lowest quality that still feels good for the context.
- Prefer smaller devices when you do not need a TV-sized screen.
- Cut autoplay loops on short-form platforms to reduce accidental watch time.
