The direct label cost is moderate: Clef Verte charges an annual membership fee on a sliding scale according to establishment size (typically €250 to €1,200 excluding VAT/year). EU Ecolabel has a similar fee. The real cost comes beforehand: assessment, operational compliance (equipment, training, sourcing), possible consultancy support. A medium-sized hotel starting out should allow €8,000 to €25,000 over 12 to 18 months to reach audit readiness, excluding major investments (particularly energy renovation).
