Cruise ships polluting UK coast as they ignore greener power options

Most liners rely on marine gas oil when docked, despite claims they reduce emissions by plugging into low-carbon electricity

Cruise ships visiting Britain are frequently failing to plug into zero emission" onshore power and instead running their engines and polluting the local environment with fumes.

The industry is under scrutiny over air pollution and contribution to greenhouse gases, with some European cities banning vessels from central ports. Cruise operators say ships can reduce emissions by switching off engines and plugging into low-carbon electricity when moored. But an investigation by openDemocracy has found that cruise ships regularly fail to use onshore power at Southampton, Britain's largest cruise port.
