About Video Streaming and Cloud Meeting Carbon Calculator
Free meeting footprint tool: duration, participants, 720p vs 1080p vs audio-only and device type into kg CO2e. For remote teams and IT leads. No signup.
Resolution is the lever
An hour of 1080p moves over 2 GB per participant; audio-only moves about 0.05 GB. Dropping to audio cuts network energy roughly forty-fold, which is why camera-off policies show up instantly here.
Devices count too
A desktop draws triple a laptop per hour. Multiply by dozens of participants and device choice rivals the network share of a big all-hands.
📐 Methodology & Reference Accuracy:
Calculations, formulas, and conversions execute locally in your web browser. Output models are benchmarked against official reference standards and updated for 2026.
🔒 This tool runs entirely in your browser. Nothing is uploaded or stored.

Frequently Asked Questions about Video Streaming and Cloud Meeting Carbon Calculator
Does turning my camera off save carbon?
Yes, substantially. Audio-only uses roughly one-fortieth the data of 1080p video, cutting that call share of emissions by a similar factor.
How much is one hour of video calling?
Roughly 0.05 to 0.2 kg CO2e per participant-hour depending on resolution, device and grid. A 100-person 1080p all-hands lands near 15 kg.
Laptop or desktop for calls?
Laptops draw about 60 W versus 150 W for desktops, so the same meeting costs less than half on laptops.
Are these exact?
No. Network energy intensity and data rates vary; treat results as comparative estimates.
