Corporate social responsibility (CSR) refers to business practices that benefit society, such as environmental sustainability efforts, philanthropic donations, ethical treatment of employees, and corporate volunteering. CSR can involve initiatives ranging from donating a portion of profits to charity to implementing greener business operations. While many companies now engage in some CSR practices, some like Ben & Jerry's and Starbucks have made CSR a core part of their overall business operations and strategies by integrating sustainability into all levels of the business.
