How do companies demonstrate corporate social responsibility?

"Many companies continue to work hard to make the world a better place to live. Recent data suggests that Fortune 500 companies spend more than $15 billion annually on CSR activities. Consider the following examples: Starbucks has donated more than one million meals to local communities via its FoodShare program and alliance with Feeding America, giving 100 percent of leftover food from their seven thousand U.S. company-owned stores. Salesforce encourages its employees to volunteer in community activities and pays them for doing so, up to 56 paid hours every year. For employees who participate in seven days of volunteerism in one year, Salesforce also gives them a $1,000 grant to donate to the employee’s nonprofit of choice. Employees who work for Deloitte, a global audit, consulting, and financial services organization, can get paid for up to 48 hours of volunteer work each year. In a recent year, more than 27,000 Deloitte professionals contributed more than 353,000 volunteer hours to their communities around the world."
