This Corporate Watchdog website has tons of useful links and information.
"CorpWatch investigates and exposes corporate violations of human rights, environmental crimes, fraud and corruption around the world. We work to foster global justice, independent media activism and democratic control over corporations.
Today CorpWatch continues to investigate multinationals that profit out of war, fraud, environmental and human rights abuse. In addition, we have also recently become an affiliate member of Friends of the Earth International where we are taking an active role in helping coordinate the corporates campaign."
