A reporting framework is a set of guidelines, standards, or indicators that help you measure and report on your CSR performance in a consistent and comparable way. Popular reporting frameworks for sustainable tourism include the Global Reporting Initiative (GRI) Standards, the Travelife Sustainability System, and the Green Destinations Standard. The GRI Standards are the most comprehensive and widely adopted global standards for sustainability reporting, covering economic, environmental, social, and governance topics. Additionally, they have a specific sector supplement for tourism with additional guidance and indicators. The Travelife Sustainability System is a certification scheme for tour operators and travel agents to improve their sustainability performance and report on their achievements. It is based on the GRI Standards and the SDGs, covering topics such as human rights, labor practices, environmental management, and customer communication. Lastly, the Green Destinations Standard is a certification scheme for destinations to assess and improve their sustainability performance while also reporting on their results. This standard is based on the SDGs and covers topics like nature and scenery, culture and tradition, social well-being, green economy, and climate and energy.
