"Greenpeace, which is urging a boycott of ExxonMobil because of its anti-global warming treaty stance, has been sued by the energy giant in France for trademark infringement. That has provided a rich PR opportunity for the media savvy environmental group," O'Dwyer's PR reports. Greenpeace altered the Esso logo by replacing the "ss" with dollar signs. ExxonMobil says that the Greenpeace-altered logo resembles the insignia of the elite Nazi SS army and that it is a "repulsion." According to O'Dwyer's, ExxonMobil fears the E$$O logo "will drive consumers away from its brand."
