Re: Greening of Streaming

Hi Dom,

Thank you very much for sharing. Do you have a link to your studies?

Figuring out the actual impact of reducing the size of the data transfer on
the carbon footprint of a website is something that some of us in this
group have been looking into for a while. Any information would be greatly
appreciated, we have generally been basing our understanding based on
Malmodin et al.'s studies.

We are also currently trying to assess if we can find any correlation
between common automated performance recommendations (e.g. Lighthouse
audits), and the energy requirements of a website on mobile devices (link

).

That being said, it's important to note that although the understanding in
the group (afaik) is that the formula/approach has room for improvement,
it's better to have a starting point and work from there, creating
awareness of the caveats, than to do nothing at all. This is a nuanced and
complex problem that will likely take time to be solved.

Thanks again!
