[Quoth]

My ereader(s) have saved maybe 250,000 pages* of print because for over 10 years I "print an ebook" instead of paper.

But most people in the West mowing the lawn, or commuting or eating x3 meat than they need, or using an electric dryer instead of a line is far more carbon impact.

As I wrote earlier, it's one of the last comparisons to worry about.

How far have the 36 paperbacks to be shipped? Are they printed in China?

EDIT
* May have miscalculated. But I used to print loads of technical stuff and I've proof read about 900 novels over last 11 years. I used to buy a lot of books too.

Replaced petrol lawnmower with corded electric and cut very much less often.
