AB - New environmental regulations are mandating cleaner fuels and lower emissions from all maritime operations. Natural gas (NG) is a fuel that enables mariners to meet these regulations; however, emissions data from maritime operations using natural gas are limited. In this study, we measured emissions of criteria pollutants, toxic pollutants, and greenhouse gases from a dual-fuel marine engine operating on either diesel fuel or NG, along with engine activity, and analyzed the impacts on pollutants, health, and climate change. Results show that particulate matter (PM), black carbon (BC), nitrogen oxides (NOₓ), and carbon dioxide (CO₂) emissions were reduced by approximately 93%, 97%, 92%, and 18%, respectively, when switching from diesel to NG. Reductions of this magnitude provide a valuable tool for port communities struggling to meet air quality standards. While these pollutants were reduced, formaldehyde (HCHO), carbon monoxide (CO), and methane (CH₄) emissions increased several-fold. A health risk assessment of exhaust plumes under stationary, at-berth conditions showed that diesel operation increased long-term health risk, whereas NG operation increased short-term health risk. A greenhouse gas and black carbon analysis revealed that, on a 100-year basis, the whole fuel-cycle global warming potential per kWh—including well-to-tank and exhaust emissions—was 50% to several times higher than diesel at lower engine loads, similar at 75% load, and lower at higher loads. Mitigation strategies for further reducing pollutants from NG exhaust are discussed, with potential to reduce short-term health risks and climate impacts.
