                                In the next section, we present a simple example to learn how to calculate an
                             LCI of a product. Nevertheless, many LCA tools in the market can help the user
                             carry out an LCI of a big variety of systems and products. The following section
                             briefly describes some of these existing software packages.

                             2.5  LCA-BASED SOFTWARE TOOLS

                             We  are concerned with LCA-based software tools developed for relatively easy
                             application because they may be applied by a wider range of users. Since it is not
                             the objective of this book to present an exhaustive list of all the existing tools in the
                             market, we have only selected some considered representatives of different applica-
                             tion fields. We have divided the tools into four sections:
                                1.  Life-cycle inventory tools. Given the data for a product, these tools will
                                   create the LCI. Thus, the life stages of the product that contributes mostly
                                   to the environmental loads considered can be identified. However, in some
                                   cases a small amount of one type of environmental load can prove to be
                                   more harmful than large amounts of others. An LCI will only provide the
                                   raw data; it will not help to identify which emissions are most significant.
                                   To do so, a full LCA is required. The LCI tools included are:

                                     of the largest database  available. All information is collected from
                                     industry through questionnaires. Data from over 23 countries are avail-
                                     able, which makes Boustead a very internationally oriented tool.

                                     and therefore limited the process to an inventory. The software package
                                     is based on an SQL database with object-oriented program structure.
