In this paper the environmental impact of a solid-state caloric heat pump was evaluated. The system employs solid-state materials as refrigerants, exhibiting caloric effects based on external fields of different natures (magnetocaloric, electrocaloric, mechanocaloric). Such technology is accounted among the Not-In-Kind cooling technologies arisen as alternative to the well-established vapor compression-based systems. To this hope a TEWI analysis is performed on the caloric heat pump and the environmental impact, depending on the caloric materials employed, is compared with a Vapor Compression heat pumping system. The results show that for almost all the mechanocaloric materials tested, with respect to the VC plant, a reduction in terms of TEWI belonging to [-75; -40] % was detected.
