Life cycle analysis is a cradle to grave approach to assessing a certain product – it starts with gathering raw material needed for production from the earth and ends with the disposal. LCA is the only international standardized method used to analyze and assess environmental impacts and their potential consequences. Through this tool, the master thesis will try to show how printed books and e-readers affect the environment from the beginning to the very end of their life. The need for reducing our carbon footprint and taking care of the environment is getting bigger and bigger, even when it comes to hobbies that bring joy to everyday lives. The question of whether printed or e-books are better for the environment is still an ongoing debate – for every good thing found, there can be also be found a certain amount of disadvantages in that particular product, which makes it hard to decide which option is better. To make the selection reliable it is important to be aware of the reader’s habits because they negatively contribute to the environmental impact. What is certain for sure is that each reader has to be aware of their individual reading habits – how many books they read, are they more of a day or night reader, etc. – and what they need and find important as a reader. The master thesis consists of the theoretical part, which gives a detailed review on theory and already conducted researches connected to the subject of this thesis. Other part of the thesis is a research that was carried out in a form of a questionnaire; results were processed, analyzed and presented in a graphic form. The thesis shows Croatian readers’ reading habits and tries to give insight into how they affect the environment through shopping, use and disposal of printed and e-book i.e. e-readers.
