Re: Greening of Streaming

 Hello Dom,

You are right. On fixed links (FTTH / xDSL), there is no linearity /
correlation between the quantity of data exchanged and the associated
environmental impacts. In France, the most in-depth study ever carried out
on this subject demonstrates this “linearity bias”. We carried out this LCA
as part of the implementation of article 13 of the AGEC law. All French
telecom operators have shared their data.

On the other hand, there is the beginning of a correlation between data
quantity and env. impacts on 4G / 5G mobile links.

At the end of the day, the key point is to avoid traffic jams during peak
hours so as not to have to deploy a new physical network (migration from 4G
to 5G for example or from ADSL to fiber for example). Because it is the
deployment of the physical network which concentrates the environmental
impacts, particularly the last mile/local loop.

Furthermore, another LCA that we carried out on streaming formally
demonstrates that it is the production of the TV which concentrates 70% to
90% of the environmental impacts. The results are more balanced in the
smartphone / mobile scenario.

Best, Fred
