Defence Research and Development Canada (DRDC) has identified several air pollutant emission control technologies, which have potential for application to marine diesel systems. 3GA Marine Ltd (3GA) identified relevant technologies, including commercially available and developmental technologies. The technologies were catalogued, critically reviewed, and assessed to determine their maturity (Technology Readiness Level/TRL). It was concluded that a majority of identified technologies are mature and commercially available; however, some of them have a limited demonstration of performance. Only a few technologies were found to be new or emerging. Most of the air pollutant emission control technologies focus on reducing concentration of nitrogen oxides (NOx), sulphur oxides (SOx), or particulate matter (PM). Some reductions of concentration of the other air pollutants, including black carbon (BC), carbon monoxide (CO) or carbon dioxide (CO2) from the marine diesel systems is being achieved by these technologies. Several technologies can be used simultaneously to achieve the best and the most comprehensive reduction of air pollutants emissions from the marine diesel system. The study identified the factors particular to naval diesels and the fuel used by them, and indicated which of the technologies have highest potential for application in Canadian naval vessels. Use of alternative fuels may be a viable non-technological method of reducing emissio
