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 U.S., and

Texas contributes the highest emissions among states in the country. Many transportation agencies 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 transportation agencies to address GHG

reductions in long-range transportation planning. This report presents a framework to link GHG emissions

mitigation strategies with long-range transportation plans. The intent of the framework was to be flexible,

practical, and equip Texas transportation practitioners with tools needed to address GHG emissions in the

long-range transportation planning process. Each step of the framework involves different stakeholders,

processes, and challenges that can occur and need to be taken into consideration. The framework can be

used to supplement federal-level guidance or policy, or serve as a starting point for TxDOT and its partner

agencies in the absence of federal guidance on the subject of transportation GHG emissions reductions. The

framework includes guidance on incorporating control strategies, performance measures, and evaluation

tools into long-range planning process to reduce GHG emissions.
