Ecosightseeing offers sightseeing tours and private charter tours in Stockholm, with sustainability at the centre of its service. Visit Stockholm says its boats run on 100 per cent renewable energy, using recycled Tesla batteries.

The operator's account focuses on M/S Sylvia, a passenger boat converted to electric power by Eco Sightseeing Sthlm AB and El & Marinteknik AB in 2019 and 2020. The companies say the conversion used reused “second life” batteries from Tesla, and describe Sylvia as the world's first fully electric passenger boat to use them. Their stated aim is to offer sightseeing and charter trips for people who want environmentally conscious experiences.

For visitors, the choice is between a sightseeing tour and a private charter. The operator's description gives the boat conversion as a specific example of its approach to sustainability. It does not state a fare, a typical tour length or a departure timetable. It also does not identify a particular season for the tours.
