The title is editorialized, and the CO2 data is just garbage. Trying to estimate the CO2 footprint just from the transfer size makes no sense. Drilling through the links to the source[0], their methodology is to take the estimated total energy use of the Internet (networking, servers, clients) and divide it by the estimated volume of end user traffic in the Internet, and multiply it by the worldwide average CO2 emissions / unit of energy. And that is supposed to give them a meaningful CO2-per-byte measure. [0] https://sustainablewebdesign.org/calculating-digital-emissions/ https://sustainablewebdesign.org/calculating-digital-emissio...
