Greenhouse gas (GHG) emissions continue to be

an important focus area for state, local, and

federal agencies. The transportation sector is the

second biggest contributor to GHG emissions in

the United States, and Texas contributes the

highest emissions among states in the country.

Many states have implemented policies and

programs targeting greenhouse gas emissions

reductions through climate action plans and

other initiatives, which cover a range of sectors

including transportation.

Also, many transportation agencies (state

departments of transportation, metropolitan

planning organizations [MPOs], and others) are

moving toward tackling the issue of GHG

emissions on a voluntary or state-level policy

basis. It is also expected that in the future,

federal regulations could require that these

agencies address GHG emissions or that

transportation funding may also be tied to a

demonstration of GHG reductions in long-range

transportation planning (LRTP).
