AIDA Cruises and Hapag-Lloyd are leading the way on efforts to sail environmentally friendly ships, according to experts.
German environmental group Nature and Biodiversity Conservation Union (NABU) has placed 6,600-berth AIDANova (built 2018) on top of the roster for using LNG for power.
Costa Cruises' 6,522-berth Costa Smeralda (built 2019), also owned by US-based Carnival Corp, shared the top spot with AIDANova for running off LNG as well.
