–We are fundamentally an Åland family business, which for decades has worked consistently to reduce our climate impact. We have long been a pioneer in the technological development of passenger ships and among the first in the world to offer biogas as a fossil-free fuel alternative. In recent years, our work has intensified further, and it is incredibly gratifying that consumers now also perceive that we take sustainability issues seriously, says Dani Lindberg, Sustainability Manager at Viking Line.
Viking Line has five of its own ships and the partly owned cruise ship Birka Gotland. With the company's newest ships Viking Glory and Viking Grace, you can reduce emissions from your trip by 90 percent by adding biogas. Read more about Viking Line's sustainability work here.
