Here are some facts about the technology environmental impact:
|Energetic consumption distribution on numerical technology|
|Numerical technology part in the greenhouse gases emissions|
|2%||Civil air transport|
|Part of the usage phase pollution (vs production phase) during smartphone lifecycle when it is kept:|
It means that when you keep your smartphone for 2 years, 90% of its lifecycle pollution was made even before you bought it.
It also means that you have to keep your smartphone at least 10 years to compensate its production phase pollution with its usage phase. (Without including the internet global pollution impact)
|HD video global impact VS smartphone playing it|
Global impact being the network & datacenters comsumption.
