State and Local Transportation Resources
Estimating On-Road Greenhouse Gas Emissions
This page contains resources for state and local planners interested in estimating greenhouse gas (GHG) emissions from the on-road transportation sector and assessing the potential of on-road travel efficiency strategies for reducing both greenhouse gas and criteria pollutant emissions.

Estimating Greenhouse Gas Emissions
- Using MOVES for Estimating State and Local Inventories of On-Road Greenhouse Gas Emissions and Energy Consumption – Final (PDF) (74 pp, 2.4M, EPA-420-B-12-068, November 2012)
This technical guidance describes how to use EPA’s MOVES models (MOVES2010a and MOVES2010b) to estimate greenhouse gas emissions and/or energy consumption from on-road vehicles in a state or metropolitan area. This final guidance replaces the public draft that was previously available on this website.

Estimating Emission Reductions from Travel Efficiency Strategies
Travel efficiency strategies are those emission reduction strategies that affect travel activity, such as travel demand management (e.g., telecommuting, transit subsidies), public transit fare changes and service improvements, road and parking pricing, and land use/smart growth.
- Technical Assistance Available: EPA’s OTAQ is again seeking state, local, or regional agencies interested in working with EPA to assess the potential for greenhouse gas (GHG) and criteria pollutant emission reductions under alternative travel efficiency scenarios.
This new effort is a follow up to the case studies completed in 2014 (described below). EPA invites letters of interest from local, regional, and state planning agencies for participation, for areas with population above 200,000. Letters of interest are due December 31, 2014. For details, see 2014 Project Description and Notice (PDF) (4 pp, 180K, November 2014).
- Travel Efficiency Assessment Method: Three Case Studies (PDF) (25 pp, 1.0MB, August 2014)
This presentation was given at a conference in August of 2014, and summarizes the three case studies EPA conducted in partnership with Boston, Kansas City, and Tucson, to assess the potential benefits of employing travel efficiency strategies in these areas.
- Estimating Emission Reductions from Travel Efficiency Strategies: Three Sketch Modeling Case Studies (PDF) (76 pp, 2.5M, EPA-420-R-14-003a, June 2014)
This report documents 3 case studies of the application of TEAM (Travel Efficiency Assessment Method) to assess the potential regional emission reductions from travel efficiency strategies. TEAM is an analytical approach that uses local travel activity information, sketch-planning travel activity analysis, and MOVES emissions modeling to estimate potential emission reductions from combinations of travel efficiency strategies. The case studies offered an opportunity for EPA to provide technical support to 3 areas interested in exploring tools to assess travel efficiency strategies, to demonstrate the capabilities of the TEAM approach, and to evaluate its usefulness at the regional scale. The resulting report documents the process, modeling and analyses performed in partnership with regional planners from Boston, Kansas City and Tucson.

- Analyzing Emission Reductions From Travel Efficiency Strategies: A Guide to The TEAM Approach (PDF) (46 pp, 2M, EPA-420-R-11-025, December 2011)
This document provides information and guidance for using the Travel Efficiency Assessment Method (TEAM) approach for assessing the potential of on-road travel efficiency strategies for reducing criteria and greenhouse gas emissions. The guide supports a preliminary evaluation of emission reductions for several travel efficiency strategies and combinations of strategies. TEAM uses regionally derived travel model data and other travel activity information, sketch-planning analysis and EPA’s Motor Vehicle Emissions Simulator (MOVES) to estimate emission reductions.

- Potential Changes in Emissions Due To Improvements In Travel Efficiency (PDF) (84 pp, 2.5M, EPA-420-R-11-003, March 2011)
This report provides information on the effectiveness of on-road travel efficiency measures for reducing criteria and greenhouse gas emissions at the national scale. The report describes an approach that uses regionally derived travel model data and other travel activity information, and sketch-planning analysis to estimate potential emission reductions from urban areas of varying size and characteristics. The results are applied to other urban areas in the U.S. with similar characteristics to estimate national emission reductions.
- Potential Changes in Emissions Due To Improvements in Travel Efficiency - Supplemental Report: Analysis of Potential Co-Benefits (PDF) (21pp, 1.7M, EPA-420-R-11-014 November 2011)
In this supplemental report, several co-benefits resulting from the implementation of on-road travel efficiency strategies or combinations of strategies (referred to as scenarios) analyzed in the March 2011 primary report are evaluated. The co-benefits from implementation of these scenarios include a reduction in health impacts associated with air pollution, reduced traffic congestion, reduced user operating costs, improved energy security, and reduction in traffic accidents.

- Transportation Control Measures: An Information Document for Developing and Implementing Emission Reduction Programs (PDF) (42 pp, 6.6M, EPA-430-R-09-040, March 2011)
This document provides information on transportation control measures that have been implemented across the country for a variety of purposes, including reducing criteria pollutants and greenhouse gases. The document describes the processes used to develop and implement the strategies and, where available, their effectiveness.

EPA’s SmartWay program reduces transportation-related emissions by creating incentives to improve supply chain fuel efficiency.
The National Clean Diesel Campaign: Join EPA, other federal agencies, regional and state governments, community organizations, industry and others to reduce diesel emissions and protect human health and the environment. The campaign has developed strategies that target diesel emissions from five specific sectors, including school buses, ports, construction, freight and agriculture.
