Tourism eco-efficiency is a term based on a lifecycle analysis approach to reduce resource use and environmental effects by the tourism industry. Examples of the tools that are used by different stakeholders to address tourism eco-efficiency optimization and sustainable tourism are Environmental Management Systems (EMS), Tourism Eco-labels, Tourism Eco-efficiency Center, the concept and framework of Local Agenda 21 (LA21), and Cleaner Production (CP). In terms of implementing sustainable tourism destinations based on the model of tourism eco-efficiency, these tools contribute to different aspects of the optimization of tourism eco-efficiency and sustainable development at various destinations. EMS provides a management system at the destination and company levels; eco-labeling allows for the development of recognition criteria; LA21 provides overall integration and coordination at the local level; and CP provides an overall implementation strategy to achieve the goals that are set. The Tourism Eco-Efficiency Centre (TEEC) was established as a non-profit, non-government, educational, and environmental management supportive center for Small and Medium Enterprises (SMEs). The TEEC helps SMEs achieve better economic and environmental performance through resource conservation, pollution prevention, reuse, recycling, and sound environmental management practices. A range of concepts about tourism eco-efficiency optimization has provided pertinent definitions of the most commonly used preventive environmental management practices, which are necessary for businesses to develop sustainability. Foreign research of the management and optimization of tourism eco-efficiency has had remarkable results and progresses, which has strong implications for the ecological efficiency optimization and management of tourism in China.
