SUBJECT : Greenhouse gas emissions: motor vehicle cabin
temperature
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
requirements.
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,

2012, or providing early reduction credit where
appropriate.
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.
Comments
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

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
vehicles.
