What is the most eco-friendly option for reading a book?

What is the impact of the book industry in Quebec today?

In 2018, the sale of new books in Quebec generated 613 million $. Digital book sales represent less than 1% of this amount. There are approximately 370,000 digital books sold in Quebec each year. Moreover, pulp and paper mills are the 2nd largest energy consumers and GHG emitters in the industrial sector after aluminum smelters, accounting for 11.9% of Quebec’s greenhouse gases[1]. Let’s take a closer look at where this footprint comes from.

What is the life cycle of a paper book?

The life cycle of a book begins with the production of pulpwood. The wood is then shredded and turned into pulp either by mechanical means (with a shredder) or, for better quality paper, by a high-temperature chemical process to separate the cellulose from the lignin. The resulting unbleached pulp is often bleached with chemicals and then sent to paper mills. There, the pulp is pressed, smoothed, dried and the paper is wound into large reels. Then comes the publishing process, printing and assembly of the book which will be distributed and sold in bookstores or on the Internet. After it’s read, the book can be stored at the reader’s home or reused, recycled, or disposed of at the end of its life.

What is the environmental footprint of a paper book?

According to a study conducted in Sweden, which has a similar energy context to Quebec, a 360-page hardcover book emits 1.2 kgCO2eq over its entire life cycle. Beyond the impacts on climate change, 50% of the environmental footprint is due to the production of pulp and paper because of heat production and bleaching. Quebec paper has a carbon footprint twice as small as the world average thanks to our low-carbon electricity. About 20% of the book’s footprint is due to the car trip (estimated at 2km) to purchase it. The best thing would be to go and buy your book on foot or order it on the Internet and have it delivered to your home.

If I buy my book second-hand, is it better for the environment?

One thing’s for sure, the more we use an object, the more we amortize its footprint! This is also the case for books. For example, if a book is read twice, half the impacts are associated with each use. So don’t hesitate to buy second-hand! Entertainment goods, including books, are the 2nd most traded second-hand goods in Quebec.

What’s the environmental footprint of an e-book?

The life cycle of an e-book begins with the content of the e-book: publishing activities, the online bookstore with e-book storage, and downloading. To read an e-book, you also need an e-reader, which is often produced in China and distributed to the reader. Reading the e-book requires electricity to operate the e-reader, and finally, the e-reader is disposed of at the end of its life.

How many books do you need to read to make your e-reader more environmentally friendly than paper books?

Having an e-reader is worthwhile if you replace 4.7 new paper books per year with digital books. That’s 14 books over the lifetime of the e-reader. However, this calculation is for a new 360-page hardcover book. If we tend to buy paperbacks that are half that weight or second-hand books, we would have to replace more than 9 books per year or 27 books over the lifetime of the e-reader.

Finally, what are the best options for reading a book?

It all depends on the type of reader you are and the habits you have!

  • For a regular reader (more than 5 books/year) who likes to buy new, an e-reader would be a good option.
  • If one usually prefers used books or paperback formats, one needs to replace more than 9 used books per year to balance the impact of the e-reader.
  • Finally, if you do have an e-reader, you might as well use it to its fullest and extend its life as long as possible.
