The holiday company Tui Cruises is sending the "Mein Schiff 7" out to sea in early summer. The new ship will not have normal fuel in its tank, but low-emission marine diesel.

In the future, the ships will run on green methanol, as Tui writes on its website. According to the company, this step is an "investment in the future and an important contribution to climate-neutral cruising." Vacationers were recently looking forward to a three-year cruise - but it was canceled. But not everyone applauds Tui's new technology, with some calling it a waste of money and saying that cruise ships are bad for the environment. The ocean giants consume huge amounts of electricity and fuel, and emissions can also reach astronomical proportions. The shipping companies want to free themselves from the stigma of being environmental offenders and are now relying on renovations and new technology. They want to make their ships more environmentally friendly and sustainable.
