It's been a difficult year for all of corporate America, but some CEOs acted especially poorly in the face of tough times.

Co-op America's Responsible Shopper program announced earlier today the year's worst corporate "scrooges"— each of whom exhibited notable greed and lack of concern for others.  It wasn't easy to make the list— the CEOs had to have played a significant role in harming consumers and the environment.

According to Responsible Shopper, the worst CEOs of the year are Charles Prince (former CEO of Citigroup), Rick Wagoner (Chairman and CEO of General Motors), John J. Harris (chairman and CEO of Nestle Waters), and Bruce Williamson (CEO of Dynegy).

The CEOs were blamed for wrecking our economy, seeking handouts from the government while fighting its regulations, developing unsustainable energy sources, and for putting profits before people and the planet.

In addition to maintaining the list of embarrassingly bad CEOs, Responsible Shopper also ranks companies in 27 categories focusing on human rights, environmental sustainability, social justice, and more.
