Greenpeace International launched a program today to develop and promote sustainable technologies. The group’s new solutions-oriented unit will work on projects like desalination systems, sustainable transportation, and renewable energy technology. Greenpeace was inspired to begin the effort after its success in helping to green the Summer Olympic Games in Sydney. Still, the group says theatrical direct action will remain the core of its campaigning. Case in point: Five Greenpeace activists were arrested this week for occupying a barge carrying equipment for a BP offshore oil project in the Arctic.
