Online Emissions Inventory Database Updates for Off-Road Equipment and Vehicles

The California Air Resources Board (CARB) is officially releasing an update to the OFFROAD2021 database (v1.0.2) on the online mobile source emissions inventory platform. This web platform is the primary tool that CARB uses to provide emission inventory details from mobile sources (both on-road and off-road) including population, activity, and fuel use. The update to the off-road emissions inventory provides a comprehensive overview of off-road equipment by integrating data from several updated off-road models including,

  • Cargo Handling Equipment: CHE2021
  • Forestry Equipment: FORESTRY2021
  • Ocean-Going Vessels: OGV2021

Additionally, this web platform includes previous inventories for Agriculture (2021 Model), Commercial Harbor Craft (2021 Model), Construction and Mining, Industrial, and Oil Drilling (2011 Model), Cargo Handling Equipment (2011 Model), Locomotive (2021 Line Haul Model, 2020 Switcher Model, 2017 Passenger and Shortline Models), Outboard Marine Tanks (2008 Model), Pleasure Craft (2014 Model), Portable Equipment (2017 Model), Recreational Vehicles (2018 Model), Small Off-Road Equipment (2020 Model), Transportation Refrigeration Units (2021 Model), and additional categories from OFFROAD2007.
