US route to energy efficiency

Authorities around the world plan for and implement measures to controll the energy use of road transports. China, Japan, US and Eu have all announced that future legislation will include measures to regulate fuel consumption or green house gases. Recently a proposal from the US National Highway and Trafic Safety Administration and the Environemental Protection Agency was presented.
Read the Fact sheet here. 
The plan is to present a regulation by summer 2011.
 
As in most other parts of the world the buses are lumped together with Heavy Duty trucks this is reasonable since trucks and buses mostly use the same engines. But, the usefull load of a bus is represented by the number of passengers rather than the load in tonnes or cubic meters. For the bus passenger for alternative is mostly metro, car, train, tram, ferry or aeroplanes.
 
I get concerned when all means of transports are not treated equally. When road transports are regulated the effect on society can either be the straight forward expected decrease of the energy use but it is also possible that detailed requirements may for example lead to less reliable or more costly technologies that in turn lead to a change in travel behaviour.
 
The propoal describes a method to calculate the fuel consumption of different Heavy Duty vehicles. The objective is to reduce the energy use, green house gases and to simultaneously create jobs, lower the cost for transportation, benefit the consumers and business and improve the competitiveness of America.
