Sustainablog has a good summation of printed books’ environmental impact:
Reducing paper use does more than save trees. Pulp and paper mills are also a major source of pollution. They release into the air CO2, nitrogen oxides (NOx), sulfur oxides (SOx), carbon monoxide, and particulates, which contribute to global warming, smog, acid rain, and respiratory problems. In addition, bleaching paper with chlorine can produce dioxin, which is known to cause cancer. Paper mills also produce large amounts of solid waste and require a lot of water. The industry is trying to clean up, but anyone who’s driven past a paper mill has smelled the challenge.
The trouble with trying to aid the environment is that if you fix one problem, you start another. Recycling is great, but the energy it takes for behemoth trucks to pick up recycled trash and then factories to actually recycle that trash can actually come out a wash. It’s frustrating. So does using ebooks actually have as deep an impact as printing?
On Salon, there’s a highly technical summary of the amount of energy it takes to read on a computer vs. printing out an article to read it. The verdict: “The contrast is quite convincing, one-tenth of a pound of greenhouse gas emissions from reading the document on the computer, versus almost one-quarter of a pound of greenhouse gas emissions for printing it out!”
Another article lays out the environmental impact of reading a newspaper on a reader and reading the New York Times on an ebook. Their conclusion: “Reading the physical version of the NY Times for a year uses 7,300 MJ of energy and emits 700 kg of co2. Reading it on a Kindle uses 100 MJ of energy and emits 10 kg of co2.”
Though it’s sad to see the demise of the newspaper and the number of
people it will put out of work, it does seem altogether necessary.
Perhaps in 100 years we’ll look back and lament the decadence of all
the paper that went wasted to newspapers, junk mail and the like.
Because much of what goes into a newspaper is wasted, as subscribers
don’t read every article. E-reading makes a lot more sense, as readers
can choose what they want to read, without discarding superfluous
material.
E-readers and Books
So far, this has covered printing out a book on your desktop or
reading a newspaper versus reading an e-newspaper. Conclusively,
ebooks have a superior environmental stamp. The general footprint for
manufacturing an e-reader (for this example, the Kindle) is thought to
be 200 MJ and 12 kg of co2. The impact of running the Kindle is
minimal. The impact of shipping is minimal as well – you’re talking the
footprint of shipping one e-reader and surfing online vs. the impact of
shipping separate books via truck, train, or plane.
The Kindle vs. New York Times article concludes:
The Kindle therefore saves 6,500 MJ and 690 kg of co2 a year. A gallon of gasoline has 131 MJ of energy and emits 8.8 kg of CO2, so switching to an e-book would be like saving 50 gallons of energy and 78 gallons of co2 emissions. A reduction of 690 kg of co2 is 3.5% of the average American’s 20 metric tons of yearly emissions.
Though less paper goes into printing a book, the minimal energy expended by manufacturing and charging a Kindle make it preferable. Put simply: ebooks are better for the environment, whatever you’re reading. As concerns about global warming grow, and the price of e-readers comes down, this could be a major issue that brings ebooks into the publishing mainstream.
