About the Workshop

The 30th CRC Real World Workshop has been cancelled

We are so grateful for your support for the rescheduled 30th CRC Real World Emissions Workshop. After careful consideration of current guidelines and discussion with the Organizing Committee, the decision has been made to cancel this years workshop. You will be able to log in to the cvent system with your original confirmation code and cancel your registration for a full refund if you are still registered.


We hope that any speakers accepted to speak at this year’s Workshop choose to resubmit their work for consideration for the 2021 CRC Real World Emissions Workshop, planned for March 7-10, 2021 in Long Beach, CA. We understand that many attendees enjoy the networking aspect of this Workshop and hope that next year we are able to gather at full strength to share new research and make new connections.



UPDATE MARCH 6, 2020 - Due to ongoing concerns and corporate travel restrictions, we are extending our cancellation deadline.  Cancellations made by midnight, Tuesday, March 10 will receive a full refund.  


Coronavirus Update

CRC is monitoring the developments of Coronavirus in the U.S., and is reviewing Centers for Disease Control and Prevention (CDC) recommendations for best practices at events. At this time, there are no CDC recommended domestic travel restrictions. 


We encourage all Workshop participants to follow preventative actions recommended by the CDC,  including:

  • Wash your hands regularly for 20 seconds, particularly before eating, after blowing your nose, coughing, or sneezing.

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 2020 workshop celebrates 30 years of research and continues to evolve in response to research needs. The 2020 workshop returns to the Hyatt Regency Mission Bay in San Diego, CA, which hosted the meeting for over 20 years.  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
