The organization sends questionnaires on climate change, water security, and other issues to major companies around the world. Based on their responses, it evaluates the transparency of each company's environmental information disclosure, management involvement, and other factors, scores the results, and publishes them. These ratings serve as an indicator for assessing corporate environmental activities.
