Sustainable development in the meetings industry is one of the key factors determining competitiveness in tender procedures and ensuring alignment between events and the ESG policies of companies and organisations. In this context, Green Key is one of the most widely recognised international environmental certifications in the hospitality sector, confirming the implementation of measurable and auditable standards in areas such as energy and water management, waste management, responsible procurement and environmental education.
For event planners, agencies and conference organisers, choosing a hotel with Green Key certification is not only a visible commitment to sustainability, but above all a practical tool for designing events in line with client requirements, supporting ESG reporting and reducing environmental impact.
