One of Greenpeace's campaign was very successful. They were able to get Facebook to pledge to move away from coal.

Greenpeace argued that Facebook consumed A LOT of coal, so they started an "Unfriend Facebook" campaign. Many Facebook users participated in this, enough to actually get the companies attention.
