ESPO congratulates the Autoridad Portuaria de Castellón and the Autoridad Portuaria de Cartagena for renewing their EcoPorts’ environmental management standard (PERS). This is the second time that Cartagena achieves the PERS certification and an impressive sixth occasion the Port of Castellón achieves the standard. These feats recognise both ports efforts in protecting the Mediterranean marine environment, facilitating the circular economy and pushing for better energy efficiency.
