Sustainability implies that society uses resources at a rate that allows for regeneration so they remain available for future use, as many resources like coal and oil are finite. Alternatives will be needed when these extractive resources run out. Accountability means an organization takes responsibility for the effects of its actions, both internal and external. It involves quantifying and reporting on these effects to affected parties. Reporting should be understandable, relevant, reliable, and comparable over time and between organizations. Transparency means an organization's external impacts from its actions are apparent from its reporting. All effects, including external impacts, should be clear to external users without hidden details so the organization recognizes responsibility for external consequences and empowers external stakeholders
