The marine program is dedicated to providing policymakers with the data and analysis they need to avoid, reduce, and eliminate pollution from the global shipping sector. Bryan is a lead author of the Fourth IMO Greenhouse Gas Study and is an expert on Arctic shipping issues, including efforts to reduce black carbon emissions and the use of heavy fuel oil. Bryan’s work highlights how maritime transportation can transition away from fossil-fueled ships to zero-emission vessels.
