Green Information Systems (IS) often require to obtain data in order to assess environmental outcomes and improve sustainable behaviours. As a result, privacy concerns can act as a barrier to the utilization of Green IS. We explore the case of smart meters, which track users’ personal energy usage data and provide real-time information, thus allowing users to reduce energy consumption. In this research-in-progress paper, we report on the development of a research model and experimental design to test the impact of trust seals, which can help to build trust and alleviate privacy concerns. For this reason, we refer to green energy and privacy seals that assess and certify the energy efficiency and privacy practices of companies. We further explore opt-out mechanisms, which give consumers the possibility to opt out of smart meter data collection that can also lead to a reduction of consumers’ privacy concerns with smart meters.
