The EPA released the newest version of its Motor Vehicle Emissions Simulator (MOVES) software, known as MOVES3, in late 2020. MOVES is the state-of-the-science mobile-source emissions model, and is the regulatory model for any emissions analysis under the Clean Air Act. EPA and its partners instrument thousands of real-world vehicles to measure emissions from various processes (e.g., running exhaust, starts, evaporation) and periodically release new input databases. MOVES3 updates the previous version of MOVES with the latest data on vehicle populations, travel activity, and emissions rates, as well as modeling improvements to better account for emissions from vehicle starts, long-haul truck hoteling, and idling. The new version also incorporates new Federal regulations, including the next phase of the Heavy-Duty Greenhouse Gas Rule and the Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule.
- Focus on updating particulate matter modeling and emissions rates, including new data on gasoline direct injection (GDI) systems.
- Updates to heavy-duty diesel and CNG running exhaust emissions rates.
- Comprehensive updates to light- and heavy-duty start emissions rates.
EBP is excited to offer cutting-edge transportation emissions analysis to our customers. From fleet electrification scenarios to regional and programmatic impact analysis, we offer insights into the environmental implications of transportation policy including transportation conformity and State Implementation Planning. EBP analysts can also help guide users in developing local emissions rates for their projects and planning. Below are some recent examples of our work:
