The ISO 26000 Guidance provides valuable conceptual and methodological guidelines for making corporate social action an effective tool through which organizations contribute to the solution of social problems within the communities they operate. These guidelines focus on their potential to contribute to the institutional strengthening of the social institutions of these communities, as well as to empower, generate autonomy, and develop skills in their final beneficiaries. Nevertheless, the academic literature has paid little attention to these guidelines. This document presents the results of pioneering research which was intended to provide information on the application of corporate social action. For measurement, a battery of 24 indicators was built and included in a structured questionnaire which was applied to a non-probabilistic sample of companies that carry out social actions. It was found that most of them apply the guidelines to a large extent and that this application correlates with the importance they assign to corporate social responsibility, with the degree to which they have incorporated it into their management, and with the construction of alliances with social organizations. Also, it was found that the application of these guidelines is independent of knowledge of the Guide and the approach to social responsibility that companies adopt.
