The transportation sector is one of the largest sources of greenhouse gases (GHGs) emissions in the United States. This study identifies scenarios for dramatically reducing future GHG emissions from the US transportation sector, specifically from light-duty vehicles (LDVs), by phasing in ammonia...

Real-world vehicle emissions differ from the legislative emissions limits for a number of reasons. Emissions can be substantially lower but in most cases emissions in real driving conditions are higher than the type-approval values. This is especially the case for NOx emissions from diesels....
