What's New List Serve Post Display

On February 24, 2009, Manufacturers Advisory Correspondence (MAC)
2009-01 was issued which outlines the process for implementing
the new Environmental Performance (EP) label. An EP label is
required to be displayed on new passenger cars, light-duty
trucks, and medium-duty passenger vehicles that are produced on
or after January 1, 2009.  The EP label replaces the Smog Index
label and provides a Global Warming (GW) score and a Smog score
on a 1-to-10 scale, a score of ten being the best/cleanest.  The
MAC explains the procedures for manufacturers to gain approval
for their EP label format and scores.  Also, the MAC explains the
evaluation process, including the process for approving
greenhouse gas emissions credits for improvements of the air
conditioning system design and control.  The MAC specifies the
information needed, including an Excel template for reporting and
calculating the GW and Smog scores that must be submitted with
each new application for certification.  The ARB approval of the
EP label’s format and contents is required before an Executive
Order certifying a test group of vehicles is issued.  Finally,
the MAC outlines the global warming scoring procedure for
Medium-Duty Passenger Vehicles certified under California’s
Cleaner Federal Vehicle rule subject only to FTP testing from
which only the measured city CO2 values are reported.  It should
be emphasized that the calculation of the GW score described in
this MAC will be superseded by another procedure upon ARB
receiving a federal waiver to implement the State greenhouse gas
regulations for these vehicles.
