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.

Explore the graphics below to understand transportation emissions in your county. Filter by year, emissions type, county, or vehicle type by using the sidebar or by clicking anywhere on the graphic. For a more detailed study of emissions, vehicle miles traveled, and vehicle age, click through the bottom graphic.

Please note that all results are estimated values of transportation emissions in Rhode Island. For more information, email Owen Jackson or call (401) 222-2808 ext. 7013.
