I agree with Lee on two points. First, investments in alternative 
modes by themselves are an inefficient way to conserve energy and 
reduce emissions. It is far more important to implement pricing 
reforms which discourage automobile travel and encourage the purchase 
of more efficient vehicles then to simply invest in public transit, 
since only about 5% of fuel savings result from shifts to public 
transit - the rest results from other changes such as the purchase of 
more efficient vehicles, and shifts to walking, cycling, ridesharing, 
and closer destinations.

Second, public transit service improvements are justified on many 
other grounds besides climate change emissions, so focusing on this 
one objective would result in underinvestment in public transit. It 
is far better to justify public transit improvements due to their 
economic and social benefits (congestion reduction, road and parking 
facility cost savings, consumer savings, accident reductions, 
improved mobility for non-drivers) rather than focusing on energy 
conservation and emission reduction benefits.

That being said, climate change concerns are stimulating a lot of 
rethinking about transportation planning goals and practices. If the 
CDM can help justify some additional investment in efficient 
transportation, I'm all for it. Ideally, climate change emission 
reduction advocates should work with other interest groups (economic 
development, traffic safety, equity, public health, consumer 
interests, etc.) to build support for the substantial changes 
required to create truly sustainable transportation systems.

Let me tell you a related story. I'm currently writing a paper 
concerning methods for monetizing (measuring in monetary units) 
carbon emissions. There are two general approaches: damage costs, 
which may be hundreds of dollars per tonne, and control costs, which 
are probably much lower, perhaps $30-50 per tonne. A colleague wants 
to use the higher value for analysis because he assumes that will 
justify greater reductions in vehicle travel, but I'm not convinced. 
A very high climate change value will justify technical solutions 
that ONLY reduce emissions (such as regulations and incentives that 
increase fuel efficiency or shifts to alternative fuels) since the 
high value implies that climate change is the dominant, while a lower 
value will justify more mobility management solutions that reduce 
total vehicle travel and therefore help achieve multiple planning objectives.
