How we calculate your digital carbon footprint
We combine three key factors to give you an accurate picture of your digital environmental impact.
Storage energy
Your device uses electricity to store files. We measure how much power your storage drive uses when idle, active, and in sleep mode.
Your energy grid
Where you live matters. We use your country's electricity grid data to calculate how clean or carbon-intensive your power supply is.
Network transfers
Uploading and syncing files uses energy too. We track how much data moves between your devices and the cloud.
Manufacturing impact
Making storage devices creates carbon emissions. We include a fair share of manufacturing impact based on how long you use your device.
Where our data comes from
Electricity data
Real carbon intensity for 28+ countries from government energy agencies and research institutions.
Device information
Power consumption specs for 30+ device types from manufacturer datasheets and independent tests.
Cloud providers
Energy efficiency data from Google, AWS, Microsoft Azure, and other major cloud services.
How accurate is this?
Our calculations are accurate to within 30%. We use peer-reviewed research and official manufacturer specifications to ensure reliability.
