FAQ Guidance on Implementation of 2008 Ozone Standard (May 16, 2013) This frequently-asked-questions guidance document discussing the implementation of the 2008 ozone National Ambient Air Standard (NAAQS).The FAQ addresses transportation conformity at the project level for metropolitan transportation plans and transportation improvement plans. In addition, the FAQ covers transitioning from the 1997 standard to the 2008 eight-hour ozone standards, and it describes the impact of the transition on the planning process.
Freight and Air Quality Handbook (June 2010) Designed to help states, metropolitan planning organizations, FHWA, and other public- and private-sector organizations develop solutions to freight-related air quality issues and emissions challenges. Includes background information on how freight contributes to air quality issues, describes strategies for mitigating freight-related pollutant emissions and improving air quality, and identifies funding and financing tools available for freight-related air quality projects.
National Near Roadway Mobile Source Air Toxics (MSAT) Study FHWA national study of toxic air pollutant emissions associated with major highway facilities required under a 2005 settlement agreement to a lawsuit challenging the expansion of U.S. 95 in Las Vegas (Sierra Club v. Mineta). FHWA website includes annual progress reports and related documents.
An Action Plan to Integrate Plug-in Electric Vehicles with the U.S. Electrical Grid, Center for Climate and Energy Solutions (C2ES) and Center for Environmental Excellence by AASHTO (March 2012). This report presents a plan for coordinating public and private sector action to accelerate the adoption of plug-in electric vehicles (PEVs) nationwide. The action plan consists of recommendations presented by a PEV Dialogue Group convened by C2ES in 2011 that included representatives from auto manufactures, electric utilities, environmental groups, and federal and state officials. The recommendations include encouraging utilities and other policymakers to create a consistent regulatory framework nationwide, optimizing public and private investment in PEV charging infrastructure, facilitating PEV rollout, and educating consumers on the costs and benefits of PEVs.
Cleaner Cars, Cleaner Fuel, Cleaner Air: The Need for and Benefits of Tier 3 Vehicle and Fuel Regulations, National Association of Clean Air Agencies (October 2011) This report provides an analysis of the costs and benefits of implementing NACAA's recommendation that EPA adopt Tier 3 motor vehicle and gasoline standards. The report finds that lowering the average sulfur content of gasoline to 10 parts per million as recommended by the association would lead to emission reductions equivalent to removing 33 million cars and light trucks from the road, at a cost of less than a penny per gallon of gasoline. According to the report, such cleaner gasoline would then allow use of improved technologies on light-duty vehicles that could yield substantial vehicle emissions reductions at a cost of about $150 per vehicle
Eco-Driving: Strategic, Tactical, and Operational Decisions of the Driver that Improve Fuel Economy, University of Michigan Transportation Research Institute (August 2011). This report that examines how eco-driving by motorists can influence on-road fuel economy of light-duty vehicles. The report defines eco-driving as the decisions drivers make to improve fuel economy, such as vehicle selection and maintenance, route selection, and driving behavior. The report finds that of these decisions, vehicle selection by far has the largest effect on fuel economy. However, the report finds that the remaining factors can contribute to a 45 percent reduction in on-road fuel economy per driver.
TRB Special Report 307, Transportation Research Board (June 2011). This report reviews policy options for achieving major reductions in transportation energy use and greenhouse gas emissions over the next half century by targeting cars and light trucks, medium and heavy trucks, and commercial airliners. The policy options examined include fuel taxes, vehicle efficiency standards, fuel standards, infrastructure investments, and coordinated transportation and land use planning. According to the committee that authored the report, significant reductions in petroleum use will require more than just tougher fuel economy standards, but a combination of measures that foster consumer and supplier interest in vehicle fuel economy, alternative fuels, and a more efficient transportation system.
America's Climate Choices, National Academies (May 2011) – This is the final report in a series of climate change assessment reports required by Congress. The report recommends that the federal government develop and implement policies that will reduce greenhouse gas emissions, facilitate adaptation, coordinate robust research programs, and actively participate in international efforts to address climate change.
NCFRP Report 4: Representing Freight in Air Quality and Greenhouse Gas Models, National Cooperative Freight Research Program Project 16. This report explores current methods used to estimate air emissions from all freight transportation modes and discusses their suitability for purposes such as health and climate risk assessments, prioritization of emission reduction activities, public education, and federal government decisionmaking. (August 2010)
Fleet Greenhouse Gas Emissions Calculator - New online tool developed by the Environmental Defense Fund and the NAFA Fleet Management Association is designed to help fleet managers measure their greenhouse gas emissions as a first step to “greening” their vehicle fleets. (April 2009)
National Capital Region Climate Change Report - Report of the Metropolitan Washington Council of Governments Board of Directors on climate change in the metropolitan Washington, D.C., region that includes significant regional greenhouse gas emissions reduction targets.
Transportation Research Record Journal, Issue No. 2011, Environmental Issues 2007 includes 22 peer-reviewed papers covering diverse subjects including efforts by departments of transportation to develop environmental management systems, vehicle emissions modeling, air quality benefits of freeway high-occupancy vehicle lanes in southern California, use of highway underpasses for large mammals and other wildlife, and others.
