Organizations and industries around the world are beginning to recognize the value of demonstrating transparency and accountability beyond the traditional scope of financial performance. Sustainability can also be explained as an impact on vital capital. According to the capital-based theory of sustainability, capital is anything that produces a flow of beneficial goods or services into the future. McElroy formulated an equation to calculate social sustainability in terms of environmental impact and regulatory impact. The article concludes with the concept that organizational sustainability is a capacity with two aspects: the first is the association's ability to adapt to ecological difficulties while maintaining its fundamental identity. The second is the ability to interface with nature in such a way as not to exploit past levels of normal and anthropo-capital needed by people (and their future generations) for their prosperity. Sustainability includes both KM and CSR. On the other hand to achieve sustainability there should be balance between internal and external environments. RESEARCH
