We find digital books the most environmentally friendly way of reading. Digital is a way of avoiding the production, material and transportation costs associated with physical books. We acknowledge that e-readers and other electronic devices used to read digital books have a carbon footprint, but, if, like us, you read a lot of books, the overall environmental impact is widely considered to be lesser than in the case of physical books. We note that it is not the same for everyone. In some situations, physical books could be the more environmentally friendly option. The environmental cost of physical books can also be greatly reduced by using libraries and/or buying second-hand, locally if possible. Currently, the practical reality is that readers often don’t have a format choice, because many books are only available in physical format. This is one of the reasons we at Lewisham Press prioritise publishing in digital format. We’d like to see a world where many more books are available in digital format.
