The California Air Resources Board (CARB) invites you to
participate in a workshop on Thursday, November 9, 2017 to
discuss updates to on-road component of the mobile source
emissions inventory. At the workshop, staff will summarize the
proposed updates to the EMFAC2017 model and present draft default
results from these updates. This will be the second and final
public workshop to discuss the development of EMFAC2017 before
its public release in December 2017.

The workshop will be held at the following date, time and
location:

Date: Thursday, November 9, 2017
Time: 10:00 a.m. – 4:00 p.m.
Location: 
Cal/EPA Headquarter Building

Information on submitting questions or comments will be provided
during the webcast for remote participants. The workshop
materials will be posted in advance of the workshop at

-Workshop Information and Background-
The past several decades have seen dramatic improvements in air
quality as a result of regulations that 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. CARB is expanding mobile source
analysis tools to support air quality planning focused on
achieving these goals.  

The EMFAC model is the primary tool that the CARB uses to assess
emissions from on-road vehicles including cars, trucks, and
buses. This will be the second and last public workshop to
discuss the development of latest version of EMFAC. The staff
provided a description of the major updates to the model during
the first workshop in June. During this final workshop, staff
will revisit major updates and provide resulting emissions impact
from these updates comparing them to EMFAC2014.
