Sustainability Analysis of Small and Medium Enterprises
 Vojtěšek, Cyril ; Basl, Josef (advisor) ; Gála, Libor (referee)
The Diploma thesis analyzes the attitude of small and medium Czech enterprises towards the Green IT and sustainability concept. Several practices such as consolidation and virtualization of servers, desktop virtualization, cloud computing, energy management, dematerialization and recycling are discussed with regards to their contribution to global sustainability. The common denominator of most of the Green IT practices is the energy consumption reduction. The increasing information technology's demand for energy is viewed as a major contributor to the global carbon footprint and Green IT practices are assessed in terms of how much energy can be saved by incorporating them in a company policy. Besides energy consumption material aspects are another significant part of Green IT. Both the toxicity of certain materials used in the manufacturing process and the increased need for proper recycling of electronic waste are discussed in respective chapters. Information technology does not only add to the global carbon footprint, but it can also provide means to reduce the emissions of other sectors. Companies can reduce their energy consumption by improving logistics (smart logistics) or buildings (smart buildings) efficiency. Teleworking is another practice which enables millions of people work outside their office and contributes to global sustainability. The analytical part presents a survey of Czech small and medium enterprises and their attitude to Green IT. The main objective of the survey is to find out how many companies have implemented Green IT into their company policy. Company representatives report on which Green IT practices they have adopted and why. Responses are analyzed and findings and conclusions are presented.
