Researching Environmental Open Data consumption needs to be a key interest when dealing with environmental issues from an information tech-nology point of view. Therefore, on the one hand, this paper aims at presenting the status quo of suitable Open Data sources in Austria. On the other hand, based on the available datasets, a novel data consumption approach relying on Linked Data Widgets and combining Linked Open Data and Environmental Open Data is presented. First, the field of research is introduced and related work is described. Then, the evaluation of datasets is illustrated and relevant re-sults are presented. Finally, a new Mashup-based approach for consuming, combining and presenting environmental data via Linked Data principles is proposed. This working example demonstrates an easy and flexible approach for the creation of innovative services, helping, e.g., in environmental decision making. Above all, the creation of such Mashups does not require any specific knowledge in the Semantic Web or environmental domain, hence enlarging the target group significantly.
