Recently, Microsoft released a new tool called Surface Emissions Estimator that helps you calculate the carbon footprint of your Surface devices. This tool offers an estimate of the carbon emissions related to production, use, and disposal of your Surface device. You can calculate the carbon footprint of your Surface devices by entering details about your device model, usage, and power settings. The calculator also suggests ways to reduce the carbon footprint.
These estimates are based on a Life Cycle Assessment (LCA) in accordance with ISO 14040 and ISO 14044.
The Life Cycle Inventory (LCI) data is based on Microsoft’s own measurements, collected from suppliers, along with industry standard and internationally available LCI databases.
