Monika Griefahn has been named director of environment and social responsibility at AIDA Cruises, becoming the line’s chief sustainability officer.

According to a statement, she is the co-founder of Greenpeace Germany, and will oversee environment and social responsibly for the German-based cruise line.

From 1984 to 1990 she sat on the board of Greenpeace International and was also the environment minister of Lower Saxony from 1990 to 1998.
