Carnival Corp has been sent a clear message on burning heavy fuel oil (HFO) in the Arctic and Subarctic.

A group of Arctic indigenous leaders and marine and environmental experts today delivered a petition with 104,000 signatures to Carnival's UK headquarters, telling it to stop using the bunker in these regions.

"We have to save the ocean. My people and my food are important," said George Edwardson, president of Arctic Slope's Inupiat community who sits on the Inuit Circumpolar Council-Alaska's board.
