Greenhouse gas emissions and air pollution from global shipping, 2016–2023
Assesses global shipping emissions over 2016–2023 using updated, state-of-the-science methods, providing new insights into the maritime shipping sector’s recent climate and environmental performance.
Vision 2050: Fuel standards to align international shipping with the Paris Agreement
This report is a gap analysis, detailing the reduction in the global average GHG fuel intensity (GFI) and the operational efficiency improvements that would be necessary for the IMO to achieve its climate goals.
Estimating greenhouse gas emissions from U.S. maritime shipping: Potential benefits of a monitoring, reporting, and verification system
A U.S. Monitoring, Reporting, and Verification (MRV) system could address several gaps in estimating current maritime emissions.
Updating marine engine emission standards using real-world data: A potential update to IMO’s NOx technical code
This brief presents new analysis using Automatic Identification System (AIS) data to estimate real-world engine load distributions and provides recommendations for changes to IMO’s NOx Technical Code 2008.
Feasibility study of future energy options for Great Lakes shipping
Evaluates future energy options for Great Lakes shipping, analyzing alternative fuels and technologies against environmental regulations, costs, and emissions, aiming to guide the industry towards decarbonization by 2050.
Fugitive and Unburned Methane Emissions from Ships (FUMES): Characterizing methane emissions from LNG-fueled ships using drones, helicopters, and on-board measurements
The FUMES report, a collaboration between ICCT, Explicit ApS, and TNO, reveals that real-world methane emissions from LNG-fueled ships, including “methane slip” from marine engines, exceed E.U. and IMO assumptions.
Real-world NOx emissions from ships and implications for future regulations
This working paper utilizes real-world measurements of ship exhaust plumes to estimate and compare emissions of nitrogen oxides (NOx) from new and old engines.
Electrifying ports to reduce diesel pollution from ships and trucks and benefit public health: Case studies of the Port of Seattle and the Port of New York and New Jersey
Combines user-friendly, reduced-complexity tools to estimate the emissions reduction potential and health benefits of electrifying ocean-going vessels, harbor craft, and drayage trucks at two of the United States’ busiest ports.
How updating IMO regulations can promote lower greenhouse gas emissions from ships
Models and compares the attained Energy Efficiency Design Index (EEDI) scores of large container and cruise ships using different fuel and engine combinations and then explores the consequences of reforming the EEDI to regulate all climate pollutants, rather than solely carbon dioxide, in its fourth phase.
Comparing the future demand for, supply of, and life-cycle emissions from bio, synthetic, and fossil LNG marine fuels in the European Union
Estimates demand for liquefied natural gas (LNG) fuel for ships trading with the European Union in 2030 and compares the life-cycle greenhouse gas emissions of using fossil or renewable LNG to consider renewable LNG’s potential to support climate goals.
