There are a lot of topics related to efforts that the cruise industry is making to "go green" and while some such as banning straws and single-use plastics are easy ... the fuel that runs these giant ships is not so clear. While there are currently no LNG or hybrid-powered ships planned for service on the west coast currently, we are home to four environmentally sensitive areas that are playing a global leadership role with reducing greenhouse gas emissions on cruise ships. This includes Alaska, Hawaii, California, and British Columbia who led the way by mandating the use of scrubbers and are now progressing to improve on that as well.
