Transportation Emissions Dashboard
Transportation is the largest emitter of greenhouse gases in Rhode Island. Vehicles account for 36% of emissions according to our 2016 Greenhouse Gas Inventory. To better understand emissions trends, the Department of Environmental Management models transportation emissions such as NOx, PM 2.5, and CO₂ using EPA’s Motor Vehicle Emissions Simulator (MOVES).
The Department modeled emissions from five different years between 2005 and 2017. Transportation emissions reported in 2005 and 2010 relied on EPA default data to estimate NOx, PM 2.5, and CO₂. For years 2015, 2016, and 2017, NESCAUM (Northeast States for Communicated Air Use Management) provided Rhode Island with projections for vehicle miles traveled (VMT), vehicle age, vehicle population, road type, and fuel usage. These projections are inputs used in MOVES to provide Rhode Island with more accurate results than using EPA’s default data.
