This document provides background on corporate social responsibility (CSR) in El Salvador. It discusses how CSR originated in Germany and other parts of Europe with a paternalistic view of businesses' moral obligations to society. In Latin America, CSR emerged amid pressure on businesses during economic downturns and a need for better economic and environmental conditions. The study surveys 463 Salvadoran businesses across sectors and sizes to determine the current level of CSR practices. It finds that most companies have codes of ethics and provide benefits beyond legal requirements. The majority of businesses support social projects and comply with international sustainability standards, showing potential to further promote CSR adoption.
