The G4 rating is a system used by the Global Reporting Initiative (GRI) to measure an organization's sustainability performance. It is based on the GRI's G4 sustainability reporting guidelines, which are considered the global standard for sustainability reporting.
The G4 rating system is based on a points system and is broken down into four categories: governance, economic, environmental, and social responsibility. Organizations can earn points in each of the four categories based on their sustainability performance. The higher the score, the better the organization's sustainability performance.
Organizations can also achieve an overall G4 rating, which is based on the combined scores from the four categories. The highest rating an organization can earn is "Leadership," which is the highest level of sustainability performance. To achieve this rating, organizations must demonstrate a comprehensive commitment to sustainability, as well as a high level of performance in all four categories.
The G4 rating system is a useful tool for organizations to measure and benchmark their sustainability performance. It also helps organizations to identify areas to improve and helps to ensure that their sustainability performance is in line with global standards.
