Euro-Topten informs consumers about the most energy efficient products in various categories and thereby aims to directly influence the purchasing decisions of individuals or professional buyers. Providers of internet-based information tools are confronted with the problem, that there is no bidirectional interaction with the users. Hence, it is difficult to evaluate if the specific needs of users are addressed, if and how the user processes this information and to what extent the information influences the user's decision making process. To study these questions, a web-based survey was conducted in two consecutive rounds. In the first round the survey focused on the assessment of the information tool itself and the motivation for using the Euro-Topten websites. This survey was online on all active Euro-Topten partner websites from October to December 2012. In total, 1791 users completed the survey. In the second round, a subset of the survey population was queried again. 1,043 participants agreed to take part in a more comprehensive follow up survey, 383 completed the second survey between May and July 2013. The second survey concentrated on the question how Euro-Topten has influenced the purchasing behaviour of the survey participants. This gave significant insights on how the information on the Euro-Topten websites has affected purchasing decisions of the surveyed users. Based on a comparison of performance indicators of the most efficient products recommended on the Euro-Topten websites with performance indicators of a base case product available on the market, avoided energy demand could be estimated for those users, who bought products from the Euro-Topten list. Based on these results, two impacts of Euro-Topten could be estimated: The influence of Euro-Topten on purchasing decision of users and the associated reductions in energy demand and CO2-emissions.
