dc.description.abstract	To combat carbon dioxide emissions, it is desirable to transition existing combustion systems to carbon-free fuels such as hydrogen and ammonia without negatively impacting air quality. However, quantitatively assessing air quality impacts of pollutants such as NOx is a nuanced process when comparing emissions across different fuels. Recently, the authors of this study published a separate paper showing that some standardized measurement approaches (i.e., measuring dried exhaust concentration) were inflating pollutant emissions by up to 40% for hydrogen combustion relative to natural gas. In this white paper, we extend this analysis to ammonia and cracked ammonia blends, showing that using concentration-based reporting approaches for comparing NOx from ammonia combustion is appropriate (less than a 3% effect), but can inflate apparent NOx emissions from fully cracked ammonia (i.e., an H2/N2 fuel blend) by 20%.	en_US
