The European Research and Transfer Network for Environmental Management Information Systems (ertemis) is a network of researchers in the field of Environmental Management Information Systems (EMIS). In recent years, the topic of Environmental Management Information Systems (EMIS) has received increasing research attention and became an increasingly popular research area. Today, companies are facing new challenges: they have to address the problem of rapid climate changes, deal with the growing public interest in ecology (e.g. Green IT, Green Logistics), and ensure environmental sustainability and energy efficency. Immense pressure is also exerted by environmental legislation (e.g. EU law) as well as by the mass media and society as a whole.
