ISO 14001 standard is the environmental certification developed by the International Organization for Standardization to describe the requirements for a certifiable Environmental Management System (EMS). The standard is included in the ISO 14000 series, developed because of the need for improved environmental quality. The current version of the ISO 14001 is the ISO 14001:2015; the purpose of the revision was to structure all the ISO standard (e.g., ISO9001) similarly and facilitate management systems’ integration.

The literature highlights that many drivers encourage companies to obtain the certification (e.g., need for an improved image of the company, pressure from customers, and ethical reasons), but there are also some barriers to its implementation (e.g., risk of spreading confidential information, reduction in productivity, and cost of the certification). However, the certification is connected to better performances indicated by the increase in process productivity and control, the reduction in resources’ consumption and waste, and the improved quality of products/processes.
