Despite recent advances in the automobile industry in reducing emissions from individual vehicles, air pollution in localities, where there are regional increases in the traffic volumes, still persist at problematic levels. Vehicular emissions are the major contributors to atmospheric NOx constituting about half of all anthropogenic emissions. Most

Successes in Stewardship is a Federal Highway Administration (FHWA) bimonthly newsletter highlighting current best practices in stewardship and environmental review from around the country.
This research, enabled by a data collection effort at the international commercial vehicle crossing at Blaine, WA, addressed three key questions regarding commercial vehicle border operations and near border operations. First, what are the unique features of border operations at Blaine, WA, that are not captured within the standard simulation tools

Presentation slides: Overview: - Quantify the emissions and fuel consumption associated with traffic congestion from Commercial Motor Vehicle (CMV) crashes - Project Description - Traffic Simulation - Emissions Analysis - Future Use with Dispersion Analysis
This memorandum focuses on the use of climate information when performing a vulnerability assessment, a topic that was discussed at the Newark Pilot Peer Exchange Workshop on May 4-5, 2011. The memorandum describes several sources of climate information, and provides some recommendations on how this information can be used by the pilots (or other t

This interim report and accompanying dataset outline the findings from the survey conducted to inform the development of the Department for Transport segmentation model of public attitudes to climate change and transport choices. The findings are based on 3,923 face-to-face, in-home interviews conducted between November 2009 and June 2010 with adul

The purpose of this research was to evaluate five transportation planning processes used in Florida to determine how greenhouse gas (GHG) emissions considerations can be incorporated into the processes. These included the federal metropolitan planning organization long range transportation planning process (MPO LRTP) and transportation improvement

The Federal Aviation Administration (FAA) facility inventory is constantly changing as newer systems supplant older infrastructure in response to technological advances. Transformational change embodied by the FAA's Next Generation Air Transportation System (NextGen) will affect the replacement of thousands of ground-based air traffic control syste

The scope, severity, and pace of future climate change impacts are difficult to predict. However, observations and long-term scientific trends indicate that the potential impacts of a changing climate on society and the environment will be significant. Projected impacts include more frequent heat waves and high-intensity precipitation events, risin

Planning for construction of roads and bridges over rivers or floodplains includes a hydrologic analysis of rainfall amount and intensity for a defined period. Infrastructure design must be based on accurate rainfall estimates — how much (intensity), how long (duration), and how often (frequency or probability). UAF and the National Oceanic and Atm

Shifts in vehicle design trends due to aviation CO2 emission metrics are explored. The combined effects of traditional performance and stringent environmental constraints on several vehicle design spaces are observed, in the presence of future technologies. Potential design implications and unintended consequences of candidate metrics are identifie

This report presents international energy projections through 2035, prepared by the U.S. Energy Information Administration, including outlooks for major energy fuels and associated carbon dioxide emissions. The International Energy Outlook 2010 (IEO2010) presents an assessment by the U.S. Energy Information Administration (EIA) of the outlook for i

This report describes the EU-27 emission trends for a number of air pollutants for the period 1990–2008. An improved gap-filling methodology used in compiling this year's EU-27 emission inventory means that for the first time a complete EU-27 time series trend for the main air pollutants (NOx, SOx, NMVOC, NH3 and CO) can be reported to the LRTAP Co

This is a technical support document (TSD) that accompanies the Federal Greenhouse Gas Accounting and Reporting Guidance (or Guidance). This document provides detailed information on the inventory reporting process and accepted calculation methodologies.
This document summarizes outreach activities and public education initiatives used around the country by State Departments of Transportation (DOTs) and Metropolitan Planning Organizations (MPOs) to educate the public on transportation-related climate change issues. Best practices were gathered from a review of online documents, outreach materials,

This report presents the results of a study evaluating the greenhouse gas (GHG) emission changes that result from individuals participating in a carsharing organization. In this study, the authors conducted a survey of carsharing members across the country to develop a robust estimate of GHG emission impacts resulting from carsharing. The results i

In October 2009, President Obama signed Executive Order (EO) 13514 that sets sustainability goals for Federal agencies and focuses on making improvements in environmental, energy and economic performance. The Executive Order requires Federal agencies to set a 2020 greenhouse gas (GHG) emissions reduction target; increase energy efficiency; reduce f

Discussion of climate change is becoming more common in transportation planning documents. Many state DOTs and MPOs are recognizing the role that transportation policies and investments play in contributing to climate change and conversely, the potential impact of climate change on transportation systems. Long range transportation plans (LRTPs) in
