Carnival Corp, Royal Caribbean International and Norwegian Cruise Line Holdings have given their backing to the world’s first cruise-led ‘green corridor.’

The initiative also has the backing of the Port of Seattle, the Vancouver Fraser Port Authority as well as the Blue Sky Maritime Coalition and Washington Maritime Blue.

The collaborative effort is aimed at exploring the feasibility of a green corridor that could accelerate the deployment of zero greenhouse gas emission ships and operations between Alaska, British Columbia, and Washington.
