Description
Get an estimate of the CO2 emissions of your web browsing activity based on the the Sustainabale Webdesign Model v4 (https://sustainablewebdesign.org/estimating-digital-emissions/). The model uses the number of bytes that are transferred when loading a web page, to estimate the associated cabon footprint.
CO2estimeter monitors the transfer sizes of web pages, via the browser's Performance API, and computes carbon emissions from that with the formulas of the Sustainable Webdesign Model v4. You can find more information on the extension's GitHub page (https://github.com/alexzurbonsen/co2estimeter).
If you encounter bugs, please also visit the GitHub page and file an issue. Much appreciated.
