Great Lakes Shipping

EPA has also completed a study to examine the economic impacts on Great Lakes shipping of the requirement to use ECA-compliant fuel. This peer-reviewed study examines three potential impacts: transportation mode shift, source shift, and production shift. It also provides information about the benefits and costs associated with applying the requirements to the Great Lakes and a description of the Great Lakes shipping sector. Documents related to this economic study are available below.

Carnival Corporation

Carnival Corporation is the most recent of several shipping companies, including other cruise lines, to apply for flexibility under the International Maritime Organization requirements to support the development of exhaust gas cleaning technology. Over the next three years, Carnival Corporation intends to develop and deploy a new type of exhaust gas cleaning system for ships—one that provides the potential to exceed the fuel sulfur standard ECA requirements, as well as provide additional benefits in the reduction of particulate matter and black carbon, at a lower cost than using lower sulfur fuel.
