eco₂rd

This is eco₂rd, an open-source browser extension that aims to help you measuring and understanding your browser traffic based energy consumption and CO2 emissions.

Website emissions?

With every website you open, there is - simply said - data transferred from the hosting provider to your machine. This data transfer comes with the cost of energy usage from different angles: from the data center of the hosting provider, from the network over which this data is transferred and from your machine as the end consumer.

eco₂rd is measuring this data transfer with the 1 byte model from "The Shift Project" that declares the energy impact of every byte transferred. Within the extension you have a few options to modify your actual footprint in order to be more accurate.

Via the options you can:

• set the country to measure your footprint with country based grid emission factor
• set, whether you want to take into consideration "complete system boundaries" (this will take a bigger picture into account, e.g. energy needed for manufacturing the servers, constructing the cable and wireless network infrastructure and manufacturing end user devices) or "narrow system boundaries" (if you only want to know the energy required to make data flow through the cable).
