As part of this third wave, standards for environmental management systems (EMS), especially the European Union (EU) Eco‐Management and Auditing Scheme (EMAS) and the International Organisation for Standardisation (ISO) 14001 standard, have become increasingly relevant since the late 1990s in all EU member states (Glachant, Schucht, Bültmann, & Wätzold, ; Montobbio & Solito, ; Papagiannakis, Voudouris, Lioukas, & Kassinis, ).
