Moving Forward with Emissions - Is it Tiers, Tears or Fears?

As International Maritime Organization (IMO) and U.S. Environmental Protection Agency (EPA) emissions requirements continue throughout the IMO Emission Control Areas (ECA), they are also forcing postponement of many new construction decisions as vessel owners and operators continue to tread cautiously along the path forward. The Marpol Annex VI program looked to correct emissions requirements while working with petroleum fuels. Technology developers continue best efforts to advance long-term solutions to reach the latest IMO zero emissions greenhouse gas (GHG) goals of 2050.
