Transportation Emissions Dashboard

Transportation is the largest source of greenhouse gas emissions in Rhode Island. Vehicles accounted for 35.5% of total greenhouse gas emissions in 2017. To better understand emissions trends, the Department of Environmental Management models transportation emissions such as CO₂, NOx, and PM 2.5 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. Explore the graphic below to understand transportation emissions in your county. Use the center control panel or click anywhere on the graphic to filter emissions by year, emission type, or county.

Please note that all results are estimated values of transportation emissions in Rhode Island. For more information, email Joseph A. Poccia or call (401) 222-2808 ext. 2774106.
