Corporate social responsibility (CSR) involves companies operating in an economically, socially, and environmentally sustainable way. The concept originated in the 1950s in response to social problems but grew in the 1980s-2000s as companies recognized broader responsibilities. CSR can provide benefits like risk reduction, competitive advantage, and aligning corporate strategy with stakeholder interests. Many large companies implement CSR through activities like community investment, environmental sustainability programs, supporting education and health causes, and responsible sourcing. CSR aims to create shared value for businesses and the communities in which they operate.
