MSC Cruises will take steps to cut down on the use of plastics on its ships.

This year, plastic straws will be phased out. They will be gone by the end of December, MSC said.

By March 2019, virtually all single-use plastics will be removed or replaced, if alternatives are available.

MSC said its efforts apply not only to 'visible' single-use plastics, but also 'invisible' single-use plastic items in the entire supply chain, replacing them with sustainable alternatives when available.

MSC Cruises' headquarters in Geneva has already engaged with thousands of partners and suppliers with a firm request to remove all plastics from its supply chain. 

"We are demanding their specific action and their commitment to support us on this journey," an MSC statement said.
