Find out how much CO2 your digital habits generate each year. Covers Netflix streaming, YouTube, email, cloud storage, Zoom calls, and social media scrolling.
HD streaming produces approximately 36g of CO2 per hour. Watching 2 hours of Netflix daily generates roughly 26 kg of CO2 per year — similar to driving about 215 km in an average car.
Your digital carbon footprint is the CO2 emitted by the data centers, network infrastructure, and devices that power your internet usage — streaming, email, social media, cloud storage, and video calls.
Sending an email produces approximately 4g of CO2 on average. A spam-free email with a small attachment can produce up to 50g. A day of 20 emails contributes roughly 80g of CO2.
A one-hour Zoom or video call with camera on produces approximately 157g of CO2. Turning off your camera reduces this by up to 96%.
Turn off your camera during video calls, delete old emails and unsubscribe from newsletters, use Wi-Fi instead of mobile data (more efficient), reduce streaming quality from 4K to HD or SD, and regularly clean up cloud storage.
Storing 1GB of data in the cloud produces approximately 2.4g of CO2 per year (0.2g/month). A 50GB cloud plan produces about 120g CO2 per year — less than driving 1 km.
Digital activities contribute 2-4% of global CO2 emissions — roughly the same as the aviation industry. Individual digital footprints are small but growing rapidly as streaming quality and data usage increase.
