What CO2Stats does

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.

No open roles recorded right now.

That does not mean they are not hiring — plenty of roles never reach a job board. The careers page below is the earliest place a new opening appears.

Check the company’s own careers page — linked at the top — before a job board. A role appears there first, sometimes weeks before it is syndicated anywhere else.
