Other #

The Other sector estimates mobile CO₂ emissions from Railroad and Shipping activities using NEI nonpoint, point, and nonroad emissions data. The sector focuses on emissions related to marine vessels and railroad equipment, filtered by SCC level two categories, and applies SCCspecific emissions factors where available. CO₂ emissions are calculated based on fuel type, state, county, and mobile source type, with temporal interpolation and emissions projections.
