About CO2Stats

CO2Stats aims to help website owners understand the electricity usage and related carbon emissions associated with site usage, and then helps site owners manage their carbon footprint. The company calculates the greenhouse gas footprint of visits to your site, based on locations of your visitors and servers, computer types, window and monitor sizes, local fuel mixes, download sizes and times. Every month CO2Stats purchase Green-E certified Renewable Energy Certificates to offset your site's CO2 footprint. Users can inspect your certificates and other environmental statistics by clicking on your CO2Stats badge.
