For most people, August 9 is just a regular day, but for some, it’s a day when we put away our smartphones, open a good book and dive into reading. If you haven’t guessed yet, August 9 is National Book Lover’s Day.
We invite you to celebrate this day with us by learning what is the environmental impact of your favourite way of reading. We’ve studied different reports and researches, and collected the most important data that defines the sustainability of paper books and e-readers. Some years ago there were published several studies that basically stated that the future of reading is with e-readers. But is that really so? With the help of a simple math equation, we will show you that an e-reader might not be the most sustainable solution for you. Let’s start by exploring the most important figures first.
Every product has its life cycle stages, in the case of books (electronic and paper) those are as follows: supply of materials, manufacturing, transportation, reading and disposal. In the table below, we compare the ecological impact of every life cycle stage for both types of books.
|Supply of materials|
|A book made of recycled paper needs around two-thirds of a pound of minerals. Mostly gravel, which is used to build roads to transport materials in the supply chain.||To produce one e-reader, the extraction of 33 pounds of minerals is required. A mineral like columbite-tantalite is used to manufacture the reader itself when sand and gravel are usually needed to build a landfill and hold the production waste.|
|For a traditional book, the manufacturer needs two gallons to make the pulp slurry that is later pressed and dried under high temperatures to create paper.||An e-reader requires 79 gallons of water to produce batteries, wiring and to refine needed metals.|
|2 kWh (kilowatt hours) of fossil fuels are needed to form and dry the sheets||100 kWh of fossil fuels are used to manufacture one e-reader. E.g. the daily average electricity usage in the UK home is 8-10 kWh. It means that you can power your home for up to 10 days with the energy used to manufacture one e-reader.|
|The carbon footprint of a single book is approximately 1.2 kg to 7 kg CO2. Depending on how big the book is and if its cover is soft or hard.||According to different sources, CO2 emission produced while manufacturing one e-reader varies between 29 and 168 kg.|
|The negative impact on our health is caused by emissions of nitrogen and sulfur oxides. These substances deeply enter our lungs, causing worsening asthma, chronic coughing and increasing the risk of premature death.||Both e-readers and books contribute to emissions of nitrogen and sulfur oxides. With the significant difference that from making one e-reader the estimated amount of harmful emissions is around 70 times greater than those from making a single book.|
Long-distance delivery (500 miles or more) of the book can create equal pollution and amount of waste as making the book in the first place.
Driving five miles to the bookstore and back can be ten times more harmful for the environment than producing a book.
|To match a toxic impact on health appearing from making one e-reader, you’d need to drive to a store 300 miles away.|
|Reading a book for an hour or two during the dark time of the day with a light bulb on will use more energy than it takes to charge an e-reader. However, if you’ve already switched to LED bulbs or read in daylight, the advantage is on a book’s side.||E-readers are extremely energy-efficient thanks to their black and white e-ink displays. You can go on reading for weeks on a single charge if you’re spending one hour a day reading.|
|A single book in a landfill with its decomposition generates double the global warming emissions and toxic impacts on local water systems as its whole manufacturing.||If your e-reader ends up being “recycled” illegally in one of the developing countries, workers will be exposed to the toxic impact of some dismantled substances. This therefore can cause multiple health issues and increase the risk of premature death. Don’t forget that child labour is a common thing in some countries and contact with toxic parts can cause some irreversible health issues at a very young age.|
So what is the approximate equivalent of one e-reader in books by the above-mentioned emissions and resources? Here is the equation:
Meaning that 34 books can be produced and have the same environmental impact as manufacturing one single e-reader. And we don’t add here any health-related numbers or the impact of global warming. This already seems like an obvious yes for books, but actually, if you read more than 30 books a year, you should definitely consider buying an e-reader. This way you will make a one-time investment into a gadget that will last you for years and after a year of use, your reading emissions will be cut to the minimum.
Ebooks are usually cheaper than printed books. See our book recommendations on sustainability below, in some cases for an ebook you will pay one-fourth of what you’d need to spend on a traditional book. The additional advantage, there are official portals where you can download some titles for free. But you need to count with an initial investment into a device itself. The prices on an e-reader can start from as little as £60 and cross the point of £200. If you decide to buy one for yourself, be sure you check on discount codes or shop via cashback links, to knock some money off your order.
We believe that these numbers in the table are improving significantly, as new technologies, certifications and opportunities are being introduced. For instance, book publishing giants like Penguin and Macmillan have already made commitments and first steps towards a sustainable future. They try to be more efficient in different aspects and even create dedicated teams to tackle environmental problems. Penguin has made a promise to become carbon neutral by 2030 and only use the paper that is FSC-certified (Forest Stewardship Council™).
Macmillan claims that most of its printer supplied paper is already FSC-certified, plus it also tries to improve its energy efficiency in the UK by switching to renewable power sources as well as it encourages eco-lifestyle among its employees. Additionally, some publishing houses are switching to vegetable-based inks and choose to make book covers from eco-friendly materials.
When it comes to electronic devices, it’s much harder to evaluate this change for the better, as the production cycle is much more complex. We’re sure there are positive changes and the emissions are getting lowered as manufacturers are becoming more energy-efficient, then they also learn how to better recycle their devices and cause less harm to the planet. We’ve found an amazing guide created by The Ethical Consumer, the UK's leading alternative consumer organisation, which evaluates and ranks e-reader and tablet brands for their ethical and sustainability efforts. Take your time to analyse the scores and methodology if you think that e-reading is your go-to option. We were surprised that the most popular e-reader, Kindle, has scored 0 out of 20 points.
Remember, whatever your chosen best way of reading is, there is always a possibility to do things better. You don’t need to buy a Kindle if you love reading paper books, as well as you don’t need to give up your e-reader if you’re all the time on the go and can’t carry a bag of books with you.
You’ve heard the buzzwords climate change, climate crisis, global warming, environmental pollution etc. Unfortunately, these words are there to stick for a long time with us being lazy or unwilling to change our habits. Since we’re here on the topic of reading, we thought it would be good to list some books that will help you be more eco-conscious in different aspects of your life. There are many approaches to sustainability, and it doesn’t matter which one you choose to adopt. The important thing is that you start doing something, whether that’s a composter on your terrace or going vegan - pick an idea you think you’re ready to commit to and the books below will be there to inspire and support you on your journey to a more sustainable living.
Author: Bill Mckibben
Goodreads rating: 4.05 out of 5
Three decades ago, American author Bill McKibben offered one of the earliest warnings about climate change. With this book he broadens the warning, arguing that humans are risking playing themselves out because of being in between two biggest threats: ecological destruction and technological overreach. In the book you will find many examples, facts and statistics marshalled not to frighten you, but to deliver the message of the severity of the current situation. He also calls to action and even suggests some possible ways out to save our future.
Author: Bill Gates
Goodreads rating: 4.2 out of 5
Bill Gates has spent years investigating the causes and effects of climate change and invested millions in the development of interesting ideas and projects. In his book, he makes a logical order of data and describes our future scenarios. He makes it clear: the solution is not in the individual fixes, but in the global plan that is deeply connected to the economy and politics. He believes that the future is in technology which already plays a major role in reducing our impact on climate. In the end, the author proposed an innovative, concrete, practical plan for achieving the goal of zero emissions and explained how we can support and control our governments in reaching it.
Author: Mike Berners-Lee
Goodreads rating: 3.86 out of 5
A book by the British researcher and writer on the topic of carbon footprinting. His book was a breakthrough in common myths once first published in 2009. He explains the carbon impact of things we use every day (cars, books, plastic bags, etc), the global (tourism, aviation, deforestation, sports events, data centres, etc) as well as in the new edition it covers social media, cryptocurrency, space tourism and more. If you think that’s a two-hundred-page list of the carbon footprint figures of different items we use, you’re seeing just one side of a coin. The goal is to open our eyes regarding some things we never thought could be harmful. The author put together the information, so we, readers, can manage our carbon footprint better.
