You leave out of Recommended Measures many transportation policies
that would be economically beneficial for the State.  You then
list many of these in the Other Measures.  Most of these policies
have been studied in detail, such as freesay congestion tolls
(which probably increase VMT and GHGs), all-day freeway tolls,
feebates, PAYD insurance, fuel taxes, and worktrip parking
charges.  The CEC has studied some of these measures, for example,
and the others have been modeled and, in some cases, empirically
studied in the U.S. and EC nations.

Most notable by its absense is a policy to direct Federal, State,
and local transportation funding to transit, walk, and bike, in
the future.  After all, this sector shows the fastest growth rate
in GHGs in most State and national projections.  It is well known
that we must invest in transit and let our highways become
congested, in order to get households to take transit, walk and
bike, reduce auto ownership, and reduce auto  travel.  Also, to
get them to move to closer-in locations.  This, for example, is
the policy in the London region, perhaps the most-modeled region
in the world.  Most transportation researchers believe that we
must reduce VMT to attain the 2020 standard.  I believe there will
be slippage in the GHG reductions projected in this draft Scoping
report.  We certainly will need to substantially reduce VMT, in
order to attain the 2050 standard in the Executive Order and in
the IPCC and Stern reports.  These transportation and related land
use changes require decades to work and so need to be adopted
sooner, not later. 

If you wish to punt these into the next 5-year round because more
political work needs to be done with cities and counties, then say
so.  This can be worded as letting them test policies on their own,
etc.  You also should state what the problem is with Caltrans not
exercising leadership on the investment issue.  It is true that
this problem extends into the Legislature, which has
simultaneously decided to build more freeways and to reduce GHGs. 
Perhaps the ARB can analyze the additional GHGs that these capacity
additions will produce and the cost to reduce a like amount, with
other policies.
