What's New List Serve Post Display

The California Air Resources Board (ARB) invites you to
participate in a webinar on Thursday, June 1, 2017 to discuss
updates to the on-road component of the mobile source emission
inventory.  At the webinar, staff will summarize updates that
have been made to EMFAC and present updated methodologies from
the upcoming EMFAC2017 model.  This will be the first public
workshop to discuss the development of the EMFAC2017 model.  

This meeting will be conducted through the GoToWebinar online
webinar system and questions from participants will be taken
using the webinar software. This event will also be recorded and
made available on the ARB web site.  Information on how to
register for this workshop will be sent out on this listserv at
least one week prior to the workshop date.

Webinar Information and Background

The past several decades have seen dramatic improvements in air
quality as a result of regulations that have reduced emissions
from stationary and mobile sources.  However, substantial
additional emissions reductions will be necessary to meet more
stringent ozone air quality standards and California’s long-term
greenhouse gas emissions reduction goals.  ARB is expanding its
mobile source analysis tools to support air quality planning
focused on achieving these goals.  

The EMFAC model is the primary tool ARB uses to assess emissions
from on-road vehicles including cars, trucks, and buses. This
public webinar workshop will discuss the development of the
upcoming EMFAC2017 version of the model. At the webinar, staff
will provide a description of the methodologies incorporated and
updates made to the model.  A subsequent workshop in the Fall
will cover model estimates and explain differences between the
new estimates and those from the prior version of the model,
EMFAC2014.
