The Maritime Administration (MARAD) and its Maritime Environmental and Technical Assistance (META) program develops documentation around policies that address maritime-related environmental issues, including emissions from vessels and ports, ballast water management, and economic incentives. MARAD wanted to expand their 2016 Energy Efficiency Report into a more comprehensive industry “guide” for improving energy efficiency and decarbonizing operations; one that would reflect the latest environmental measures and rapidly evolving technologies. MARAD’s Office of the Environment and Innovation engaged Glosten to help accomplish this by developing a forward-looking Energy Efficiency & Decarbonization Technical Guide that helps operators make adjustments in the near-term and plan major changes for the long-term.

For the expanded guide, Glosten reviewed the current state of energy-efficient and carbon/emissions-reducing technologies to determine which should be added, retained, or removed, and reached out to key technology developers. The authors distilled the expansive and changing landscape of decarbonizing fuels, efficiency technologies, and operational measures into a quick-access and reference-ready guide for ship operators and policy makers alike.

The expanded guide now encompasses decarbonization methods and incorporates up-to-date information about energy-efficient and zero-emissions technologies, with updated tools and features to help operators evaluate their options and make informed decisions for improving their fleets.
