This report covers the period October 1, 2019 through September 30, 2020. The Center was established by the authority of FAA solicitation 13-C-AJFE-Solicitation. During that time the ASCENT team launched a new website, which can be viewed at ascent.aero. The next meeting will be held virtually April 27-29, 2021.
The Oregon Department of Transportation (ODOT) monitored the surface waters in and around the Salmon River Estuary on the Pacific coast of Oregon for approximately ten years. Two ODOT highways are associated with this estuary. Oregon State Route 18 runs along a portion of the southern margin of the estuary while U.S. Route 101 runs directly across

This Transportation Research Synthesis will develop and deliver a state-of-practice survey on metrics and/or performance measures to track climate resilience in transportation systems.
The energy-water nexus (i.e., availability of potable water and clean energy) is among the most important problems currently facing society. Ammonia is a carbon-free fuel that has the potential to reduce the carbon footprint in combustion related vehicles. However, ammonia production processes typically have their own carbon footprint and do not ne

The information contained in this report is organized as three separate but related research studies. Collectively, these studies investigate the impact of climate change and sea level rise on transportation infrastructure within portions of the Hampton Roads region of Virginia. The first report "Impact of Sea Level Rise on Roadways in the Hampton

In the global search for the right alternative energy sources for a more sustainable future, hydrogen production has stood out as a strong contender. Hydrogen gas (H2) is well-known as one of the cleanest and most sustainable energy sources, one that mainly yields only water vapor as a byproduct. Additionally, H2 generates triple the amount of ener

The significant change in climate is evident from the records of increased temperature, changed precipitation pattern, increased frequency of extreme weather events like storms, floods, and so forth. Like other infrastructure highway infrastructures also suffer the consequences of these climate change. Since the hydraulic design of these infrastruc

The main goal for EnviCom Task Group 3 'Climate Change and Navigation' was to discuss the climate change related issues for the navigation sector, and how to understand and to deal with the knowledge about climate change and the various projected scenarios.
This study focuses on assessing the demand for plug-in hybrid electric vehicles (PHEV) in Wisconsin and provides near term recommendations to manage its impacts on the State's electrical grid.

Increasing the efficient use of existing energy supplies is widely acknowledged as the fastest, cheapest, and cleanest way to meet future energy needs. Energy Efficiency: The First Fuel examines the strong U.S. record of tapping efficiency as a resource, and the accelerated efforts by individuals, organizations, and governments to squeeze greater p

This report summarizes the experience and results from a demonstration of a fleet of battery electric buses (BEB) operated by Long Beach Transit (LBT) in southern California. In 2011, LBT was awarded a $6.7 million grant through FTA’s Transit Investments for Greenhouse Gas and Energy Reduction (TIGGER) program to fund an electric bus pilot project.

This guidebook provides the field with a process to assess and address climate change impacts on Forest Service transportation assets at the local and regional levels. The guidebook is intended to strike the balance between being specific enough to be implementable and flexible enough to accommodate a variety of needs and challenges. The target aud

Concerns about global warming are focusing increasingly on the contribution of human activities, including aviation. Jet aircraft are among many sources of greenhouse gases-gases that can trap heat, potentially increasing the temperature of the earth's surface and leading to changes in climate. According to a recent report by the National Research

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 following report was developed for the California Department of Transportation (Caltrans) and summarizes a vulnerability assessment conducted for the portion of State Highway System (SHS) in Caltrans District 6. Though there are multiple definitions of vulnerability, this assessment specifically considers vulnerabilities from climate change. Cl

Under the Federal Aviation Administration's (FAA) Aviation Climate Change Research Initiative (ACCRI), non-CO2 climatic impacts of commercial aviation are assessed for current (2006) and for future (2050) baseline and mitigation scenarios. The effects of the non-CO2 aircraft emissions are examined using a number of advanced climate and atmospheric

The Federal Transit Administration (FTA) collects and analyzes data from across the country on public transportation fuel use, vehicles deployed, rides taken, and other key metrics. These data, taken from the National Transit Database and combined with information from the U.S. Department of Energy and the U.S. Environmental Protection Agency, prov

Transportation infrastructure is typically designed and built based on the assumption that the risks associated with climate and weather conditions at any given location do not change over time. Today, however, climate change is altering the risk of many types of weather extremes including the frequency and/or severity of high temperatures, heavy p

This report assesses the potential of substitutes for gasoline to reduce emissions of carbon dioxide and other greenhouse gases (GHGs) by automobiles and light-duty trucks. It estimates reductions in future GHG emissions under specific assumptions about growth in light-duty vehicle travel and the replacement of gasoline by various other fuels, both

Exploiting a rich data set of new vehicle registrations in 22 U.S. Metropolitan Statistical Areas from 1999 to 2006, we analyze the determinants in the demand for hybrid vehicles and examine government programs that aim to promote the adoption of hybrid vehicles. We find that both the recent run-up in gasoline prices from 1999 and federal income ta
