Norwegian cruise operator Hurtigruten, known for its trips to the environmentally sensitive Arctic, is powering ships with fish scraps.

A fleet of the liner’s floating luxuries will soon be powered partly through liquified biogas — a type of fuel naturally produced as dead fish and other organic waste decompose, the company said in a press release, according to CNN.

Traditional high-sulphur fuel favored by most of the cruise industry’s ships produces sulfur oxides, which contribute to the acidification of seas and rain. But concern for the environmental impact of this fuel led the International Maritime Organization to set a 0.5% sulfur limit on marine fuel by 2020. Enter fish fuel.

“While competitors are running on cheap, polluting heavy fuel oil, our ships will literally be powered by nature,” Hurtigruten Chief Executive Officer Daniel Skjeldam said in a statement. “Biogas is the greenest fuel in shipping and will be a huge advantage for the environment. We would love other cruise companies to follow.”
