Probably not much, and depending on how you look at it, it could use more.
As with most things, our usage is the real problem. When #tech (process change, etc) allows + #feedback to flow & accumulate in new places in the system, it won't be long until the #system adjusts to this new stock.
The 'paperless' promise never came with an #environmental impact study or similar studies for the #economy, behavioral consequences, etc.
An almost entirely overlooked result, across the board wherever you look in #society, is that these adjustments are functionally equivalent to removing checkpoints where flow is bottlenecked. In our market-based system, lowering costs to consumers means increasing said behavior-- at least indirectly, as a consequence of #corporate marketers' narratives of abundance & perpetual #growth.
Now sprinkle in some competition, and the race to the bottom begins: when you can't lower your price anymore (to attract biz away from comp) you offer these 'packages' of increasing use, all ending at the constraint of "unlimited". (>bandwidth magnifies use too)
It's a nice plot-twist in the standard narrative of the #Tragedy_of_the_Commons. Unfortunately, reasonable & moral actions such as yours are not the same ones that will resolve into necessary #sustainable change.
