Corporate social responsibility is an important task that every company should and need to take nowadays. In 2010, Pepsi Refresh Project, as a cause marketing program, apparently didn't help PepsiCo. to achieve a for-profit company's objective to increase sales; nor did it help to change PepsiCo's brand image as a social-friendly company then. Instead, it induced lots of backlashed voice from the consumers who perceived the Refresh Project as inauthentic/inconsistent.
However, Grameen Danone Foods Ltd., founded as a social business, seemed to be more successful to contribute to the society and fulfill its objective "to be profitable to ensure economic sustainability".

What do you think Grameen Danone has done right and how does it do good to the society as a social business?
