This master thesis applies strategy and marketing approaches to the Austrian Greenhouse Gas Inventory. The focus is on methods and tools that utilize market opportunities through an understanding of customer behavior and needs. The thesis identifies challenges that are relevant for customizing a non-profit process that so far has been optimized in serving only the state as its sole customer. Main results are specific recommendations on how the aim of customization can be defined in non-monetary terms, how and when customers should be involved, and on how an initial set of specifications for a Configurator would look like. It moreover addresses the question of "what business the inventory is in?" and defines market segments and a potential target market for the Austrian Greenhouse Gas Inventory.
