2021 CRC Real World Emissions Workshop

About the Workshop



The inaugural CRC emissions workshop convened as the “CRC-APRAC vehicle emissions modeling workshop” on October 30 and 31,1990.  It was the first time that representatives from government agencies, universities, automotive and oil industries, and consulting and testing firms active in examining vehicle emissions inventories were assembled in one location.  117 participants engaged in discussions and twenty speakers presented in four technical sessions including EMFAC7 and MOBILE4 models, model evaluations, laboratory vehicle emissions studies, and on-road emissions studies.  

In three decades of annual events, the Real-World Emissions Workshop has grown into an international event, hosting over 250 participants representing more than a dozen countries.  Its 30-year history has spanned an era where the public has benefited from large reductions in vehicle tailpipe emissions, brought about by improvements in emissions control technologies and fuels, leading to demonstrable improvements in air quality.  The 2021 workshop celebrates 30 years of research and continues to evolve in response to research needs. Topics areas this year are expected to include novel and new research in: 

  • Air Quality 
  • Emissions Modeling 
  • Off-Road / Nonroad Emissions 
  • Emissions Measurement Methods 
  • Fuel Effects on Exhaust Emissions 
  • Improving the Emissions Inventory 
  • Particulate Emissions and Measurement 
  • Emissions Control Measures (I/M) and OBD 
  • In-Use Emissions for Light- and Heavy-Duty Vehicles 
  • Non-Tailpipe Emissions 
  • Sensors and New Technology 

CRC welcomes your participation on March 8-11, 2021, to celebrate the 30-year Anniversary of the CRC Real World Emissions Workshop. 

The technical program will be hosted on WebEx from approximately 10:30 am. -2:30 p.m. (ET) Each day.  At the conclusion of the technical presentations, an interactive session will be held from 3:00-4:00 p.m. (ET) each day.  A special session will be held from 9:00a.m.-10:00 a.m. Wednesday a.m. to interact with International presenters.
