Corporate social responsibility (CSR) refers to a company's sense of responsibility towards the community and environment where it operates. This includes reducing waste and pollution, contributing to social programs, and earning returns for shareholders. One example is Microsoft's YouthSpark project, which has provided IT training to over 500,000 young adults in underserved communities across 27 Indian states with an investment of 47 crore rupees. Microsoft is also committed to increasing energy efficiency and using renewable energy sources like wind and solar power.
