  • Trends in Texas GHG EmissionsTexas (if it were a country) would rank seventh in the world for its GHG emissions Transportation is 30% of total CO2VMT increased 10% per year from 1990 to 2000VMT increased 10% from 2002 to 2007 for the Houston regionPopulation growth at about double the rate of the country

    *

  • Policy IssuesThe 2009 EPA endangerment finding is the most powerful federal policy to date State level programs in Texas:TERPLIRAPHB 1795 requires TCEQ to develop an inventory of voluntary actions to reduce CO2 emissions

    *

  • Policy IssuesTexas municipal-level actions:

    City of Houston and City of Austin working on a comprehensive climate action planBut most municipalities still waiting for state and federal policy makers.

  • Methodology for Project Level AnalysisAn analytical tool in the form of a spreadsheet-based calculatorCombines the emission estimations of each project with the emission reductions from mitigation strategiesBased on user input data*

  • Methodology for Project Level AnalysisCalculate on-road mobile source GHG emissions for baseline year Build vs. No-Build at completion year for the project.Calculate on-road mobile source GHG emissions for future years.List of GHGs control strategies.Quantifications of CO2 emission reductions associated with the selected mitigation options.Calculations will involve the use of EPAs MOVES model for CO2 emissions factors and activity data from the travel demand model.

  • Selection Criteria for Control StrategiesCost effectivenessPotential emission reductionsApplicability

  • Control StrategiesHOV lanesTTI and Caltrans studies showed lowest levels of gasoline consumption against the no-build and build-general purpose.TransitEx: expansion transit infrastructure, ridership increased 10,181 MMtCO2 (by 2012 Miami-FL)*

  • Control StrategiesMixed Land Use Development or Livable CentersEncourage jobs/housing/commercial proximity and developments along transit corridors 18 MMtCO2 by 2020, California

    Electrification of Vehicle FleetPZEV emit half the amount of CO2

    *

  • Control StrategiesCarbon Sequestration

    Trees are a good sink of CO2Upto 6 MtCO2e reduction per tree for a 40 year life spanNeed to be taken into account how to manage them

    *

  • Control StrategiesEco-Driving and Anti-Idling Policies

    Outreach program endorsed by 20 states info about vehicle maintenance and driving habits 2.2 MMtCO2 by 2025, MichiganReduce idling time for heavy duty diesel trucks 1.4 MMtCO2e by 2020,California
