                                                               SB 1328

           SUBJECT  :    Greenhouse gas emissions:  motor vehicle cabin  

           SOURCE  :     Exatec, LLC

           DIGEST  :    This bill requires the Air Resources Board to  
          consider specified matters if adopting or amending  
          regulations to reduce motor vehicle cabin temperature in  
          order to reduce greenhouse gas emissions.

           Assembly Amendments  specify that the Air Resources Board  
          (ARB) shall consider such matters when adopting or amending  
          regulations instead when the ARB is developing regulations.

           ANALYSIS  :    Existing law, under the California Global  
          Warming Solutions Act of 2006:

          1. Requires the ARB to determine the 1990 statewide  
             greenhouse gas (GHG) emissions level and approve a  
             statewide GHG emissions limit that is equivalent to that  
             level, to be achieved by 2020.  ARB must adopt  
             regulations for reporting and verification of GHG  
             emissions, monitoring and compliance with the program,  
             and achieving GHG emission reductions from sources or  
             categories of sources by January 1, 2011, to be  
             operative on January 1, 2012, subject to certain  

          2. Requires the ARB to prepare and approve a scoping plan  
             for achieving the maximum technologically feasible and  
             cost-effective reductions in GHG emissions from sources  
             or categories of sources of GHGs by 2020.  ARB must  
             evaluate the total potential costs and total potential  
             economic and noneconomic benefits of the plan for  
             reducing GHGs to the state's economy, and public health,  
             using the best economic models, emission estimation  
             techniques, and other scientific methods.  The plan must  
             be updated at least once every five years.  

          3. Authorizes the ARB to adopt GHG emission limits or  
             emission reduction measures prior to January 1, 2011,  
             imposing those limits or measures prior to January 1,  



                                                               SB 1328

             2012, or providing early reduction credit where  

          This bill requires the ARB, if adopting or amending  
          regulations to reduce cabin temperatures in vehicles in  
          order to reduce GHG emissions, to consider the following:

          1. Potential reductions in air conditioning use that can be  
             achieved while a motor vehicle is moving, in addition to  
             reductions in air conditioning use when a motor vehicle  
             is parked.

          2. Potential conflicts between, and relative benefits of,  
             motor vehicle cabin temperature reduction requirements  
             and technologies that provide motor vehicle GHG emission  
             reductions through various means.

          3. The flexibility necessary to achieve overall maximum GHG  
             emission reductions from motor vehicles.

           Vehicle Cabin Temperature Standard  .  The concept behind  
          'cool cars' is to keep cars and light trucks cooler so less  
          fuel is needed to keep the cabin temperatures comfortable,  
          thus reducing fuel consumption and GHG and other  
          pollutants.  In May 2008, the ARB embarked on a rulemaking  
          process for cool cars as part of the overall GHG reduction  
          strategies.  On June 25, 2009, ARB adopted the cool car  
          regulation that required new vehicles starting with the  
          2012 model year to be equipped with solar control windows.   
          These windows limit the amount of solar radiation entering  
          the vehicle, allowing the air conditioning units to be  
          downsized or used less frequently.  Less air conditioning  
          use or smaller air conditioning units translates into less  
          fuel burned and lower GHG emissions emitted by the vehicle.  
           ARB staff estimated that the requirements when fully  
          implemented would have prevented over one-million metric  
          tons of CO2 from being emitted into the air.  The solar  
          controlled windows used a 'glazing' technology that blocked  
          solar energy and reduced heat build up in the car.

          On March 25, 2010, the ARB withdrew the regulation approved  
          on June 25, 2009, from the rulemaking process after  



                                                               SB 1328

          determining that insufficient time remained on the  
          rulemaking calendar to achieve consensus on the rule and  
          problems with the metallic glazing.  The ARB plans to  
          revisit a different approach to keeping cars cool in the  
          next phase of motor vehicle regulations, which will be  
          phased in starting with the 2017 model year.

          According to the author's office, this bill will provide  
          policy guidance to ARB when it resumes its work on a  
          vehicle cabin temperature standard, to broaden the factors  
          it considers in how air conditioning based vehicle  
          emissions are achieved and to consider how it can avoid  
          potential conflicts between various beneficial new  
          technologies that will reduce vehicular GHG emissions.  It  
          ensures that the ARB has all of the necessary tools to  
          provide flexibility to the auto and related industries with  
          certain regulations in order to achieve the greatest GHG  
          reductions possible associated with light and medium duty
