Conducting a life cycle inventory (LCI) is the first step in carrying out a life cycle analysis (LCA). However, life cycle inventories are often based on surrogate or generic data because site specific data from the facility, product, or process in question does not yet exist or cannot be measured. This thesis investigates the effects of using different types of data on the credibility of life cycle inventories, and evaluates differences that exist between using site-specific data and conceptual sources of data. In particular, the thesis examines if a life cycle inventory developed by assuming data from external sources for an industrial process is reasonably comparable to a life cycle inventory using site-specific data for this same process: the former scenario is the situation most LCA practitioners find themselves in. The pre-treatment process for automotive painting is used as a case study. Two sources of data are used to develop the life cycle inventories in this thesis: one facility provides the actual or site specific data, while a second facility provides the surrogate data that will be used to model the process.
