8.3.6 LIMITATIONS OF SITE-SPECIFIC IMPACT ASSESSMENT IN THE
REMOTE LIFE CYCLE

The LCA carried out for the universal remote is an excellent illustration of the
limitations of site-specific impact assessment. The identified impacts in Table 8.15
are mainly related to the manufacturing, but this does not mean that the impact
occurs where the manufacturing is carried out. Conversely, in the case of this
universal remote LCA the manufacturing stage only sums up the total life-cycle
