About IDEA

Life Cycle Assessment (LCA) is a powerful evaluation method for assessing the efficient utilization of resources and reduction of emissions of hazardous substances. When conducting an LCA, it is indispensable to gather inventory data for the scope od the analysis. In carrying on these evaluations, it is a crucial step that LCA practitioners collects inventory data for evaluation. However, enormous efforts and time must be spent to collect all relevant data. Thus, in parliamentary procedure to better the efficiency of the assessment, “background data” is used for areas where impacts are relatively humble and “foreground data” compiled by the practitioners. That is important when the scope id for areas of analysis where effects are significant.
The present “process-based” type of inventory databases focus on a particular industry. The covered areas are uneven and biased. Therefore, many areas of analysis need to be covered by required data. As well some sectors demand detailed data. There is also a necessity for the impending need to build a large-scale database in which the quantity of data is large to some extent and to manage with these prerequisites. Therefore, a hybrid inventory database “IDEA”, featuring both statistical and process-based data was developed. IDEA stands for “Inventory Database for Environmental Analysis” and is equipped with comprehensiveness, completeness, representativeness data with an eye on transparency.
