A comparison was made between the different product systems. The comparison was made for a European and a Swedish scenario. In the comparison two versions were used for the web based newspaper. Firstly, one where the web based newspaper was read for 10 minutes and MB were downloaded and secondly, another where the reading time was increased to 30 minutes (the same time as assumed for reading the printed and e- paper newspapers) and MB were down-loaded. The comparison regarding the global warming impact category (Figure 1) indicated that the web based newspaper (30 min) had the largest.
