Perhaps that does not sound like much. But in the US alone, where 767 million paperback books were sold in 2023, this is equivalent to the electricity use of more than 150,000 homes for a year.Forest loss, paper production and printing, and transport of books are generally the largest contributors to the carbon emissions of printed books.

So, using less wood fibre, and shipping lighter loads, are important ways to reduce the emissions of print books (as well as the costs of producing them).One simple method is reducing the thickness of the paper. Some publishers are turning to subtly thinner paper. There are limits to this: the most lightweight paper may be less durable. And for certain types of books, including art books, there’s a preference for heavier paper.Yet between these extremes, most readers are unlikely to notice the difference.

Nor would most readers notice the design tweaks that allow more text to fit onto each page - as long as designers ensure that the text remains easy to read.The publisher HarperCollins

that require less ink and paper. This has resulted in savings of hundreds of millions of pages.

A leader in this field is Sustainable Typesetting, a project of the design and typesetting company 2K/DENMARK. One of the company’s focus areas is complex typesetting for long texts, including Bibles.She recently got diagnosed with ADHD - attention deficit hyperactivity disorder - which has helped her understand why she found her A-level revision period so difficult.

Emma says she sometimes finds it hard to focus until a deadline is drawing closer."I need the pressure - but I also hate it because I get so stressed and so burnt out so easily," she says.

Emma also says she sometimes struggled to get started with revision - even though she wanted to do it - because of how her ADHD affects her ability to start tasks, and organise revision sessions into manageable chunks."I think there's a lot of shame and guilt, because I thought I was being lazy," she says. "You feel really rubbish about yourself. Then when I get really overwhelmed I get headaches."
