Phase 3

In phase 3 the collected data are processed and the actual result of the LCA is given. The emissions of a product are divided into different environmental impact categories. The result can be presented in different ways, for example for the entire lifecycle or for single parts of the lifecycle but always within the environmental impact categories. An overview of phase 3 is given in figure 12 below followed by a description of the different parts of the figure.
