**1.5 Aim of this book chapter**

The aim of this chapter is to comparatively assess the impact on the environment of two types of electromagnetic shields:


EMSE was experimentally determined according to the ASTM ES-07 (TEM cell) standard and represented in **Figure 5**.

Since magnetron sputtering copper coating enhances the shielding effectiveness of the woven fabrics with 8–10 dB on the frequency domain of 0.1–1000 MHz, the woven fabric with inserted metallic yarns was modeled considering a smaller distance of the grid in order to reach the same EMSE. The increase of EMSE in smaller grid distances is given by relations of the EMC literature [6]. This approach was considered in order to have the same LCA functional unit for both textile shields, namely: **one sqm of shielding fabric with 50 dB at 100 MHz.**
