Cruise industry adopts cold-ironing and data monitoring strategies

The cruise industry, along with the wider shipping sector, is adopting strategies to achieve net-zero greenhouse gas (GHG) emissions by or around 2050. One significant strategy is shore-side electricity (SSE), also known as “cold ironing” or shore power systems. Up to 98% reductions of  CO2 and other pollution emissions can be achieved by shutting down onboard power generation from diesel engines and connecting to shore power.  The Cruise Line Industry Association (CLIA) indicates that 40% of its global members’ ships are set up to operate in SSE in 29 ports, which is up 20% year over year, and 98% of new builds ordered through to 2028 will be fitted with SSE systems or be configured to add it in the future.

Unfortunately, determining exactly how much emissions are reduced by shore is complex. In the US, there are nine regions, with each region employing its own calculation tool. The EPA has its Shore Power Emissions Calculator (SPEC), but many calculations begin with the number of KWH consumed. Meanwhile, cruise lines are tracking their usage as part of their environmental reporting.
