Perhaps. Or perhaps what uses more over a lifetime is an ebook that is bounced around from device to device which all turn to toxic e-waste after a few years, constantly communicating with always-on servers for account data and DRM authentication hosted in a data centre based in a region powered by fossil fuels. All while a paper book just sits on a shelf causing no further environmental impact - potentially for hundreds of years.

To be fair, nobody’s preference for paper books or ebooks will change the environment in any meaningful way - the problems are much more systemic and require radical action from an unwilling corporate and political elite that has been ignoring the problem for decades.
