The purpose of this study was to reveal the present situation of Sustainability reporting in 72 organizations, including many different business and industrial sectors. I sought to establish what kind of information they were including in their reports and to observe the growing trend of creating such reports. According to the sectoral matrix analysis conducted, most of the organizations do not share information on activities related to sustainability, and in most cases these reports are nothing more than reduced figures and percentages of natural resources used during their activities In addition, they rarely conducted a Materiality analysis/matrix. This situation unveils the lack of sustainable initiatives and specific proposals Nevertheless, it has also demonstrated the fact that these national enterprises are just starting to make inroads in these kind of Reporting based on GRI guidelines.
