This report is a guide for airports that wish to reduce or eliminate greenhouse gas (GHG) emissions from existing buildings and operations. Reaching carbon neutrality typically requires the use of multiple mechanisms to first minimize energy consumption and then maximize renewable energy use. This report provides a flexible, step-by-step outline fo

This document presents highlights from five research reports on airport greenhouse gas (GHG) emissions inventories. It presents the most salient findings for policy makers and U.S. airports seeking to better understand and inventory airport GHG emissions. The emphasis in this summary is to provide recommendations on reasonably accurate and low cost

Although the New York State Department of Transportation (NYSDOT) has not yet published guidance on addressing climate change impacts as part of the NEPA process, the organization has been considering the potential impacts of sea level rise on proposed projects during the NEPA process for several years. NYSDOT is concerned about the impacts of clim

The Florida Department of Transportation’s (FDOT) First Coast Expressway project aims to provide a multi-lane limited access toll facility to connect Interstate 95 (I95) in St. Johns County and Interstate 10 (I-10) in Duval County. This project has proposed 46.5 miles of roadway, including a new bridge over the St. Johns River. Figure 1 shows the l

The Massachusetts Department of Transportation (MassDOT) South Coast Rail Project aims to restore 52 miles of commuter rail service between Boston and the Massachusetts South Coast in order to enhance public transit systems. Figure 1 shows the project area with existing stations, new stations, new layovers, and reconstructed stations marked along t

This manual provides technical guidance and methods for assessing the vulnerability of transportation facilities to extreme events and climate change in riverine environments. The focus is quantifying exposure to extreme flood events considering climate change and other sources of nonstationarity. It is anticipated that there will be multiple uses

Successes in Stewardship is a Federal Highway Administration (FHWA) bimonthly newsletter highlighting current best practices in stewardship and environmental review from around the country.
Structural health monitoring (SHM) using ambient vibration has become a valuable tool in evaluating and assessing the condition of civil structures. For bridge structures, a vibration based SHM system uses the dynamic response of a bridge to measure modal parameters. A change in a structure's modal parameters can indicate a physical change in the s

In the coastal zone, seaports and their intermodal connectors are key types of infrastructure that support the global supply chain, provide regional economic activity, local transportation system services, and community jobs. The protection of coastal communities and their ports has been taken for granted during a prolonged period of climate stabil

This report summarizes the findings of an experimental investigation into shrinkage, and the mitigation thereof, in alkali-activated fly ash and slag binders and concrete. The early-age (chemical and autogenous) and later-age (drying and carbonation) shrinkage of sodium silicate-activated fly ash and slag binders was evaluated in accordance with re

The primary aim of this study is to help aviation jet fuel purchasers (primarily commercial airlines and the U.S. military) to understand the sustainability implications of their jet fuel purchases and provide guidelines for procuring sustainable fuels. This study reviews literature on life cycle analysis and sustainability and identifies the regul

The New York State Department of Transportation (NYSDOT), in partnership with The Nature Conservancy (TNC), wrote this report in fulfillment of a grant from the Federal Highway Administration’s (FHWA) Climate Change Resilience Pilot Program. The purpose of the program was to pilot approaches to conduct climate change and extreme vulnerability asses

The ability of transportation agencies' to effectively manage, operate, and maintain a safe, reliable transportation system is being threatened by a changing climate. Extreme weather events are becoming more frequent and intense due to climate change, and long-term climatological trends are slowly but inexorably changing how transportation systems
