Emissions, Environment

This article, published by the Environmental Protection Agency, answers questions surrounding six common myths about electric vehicles. It provides straightforward answers and offers up additional resources for further investigation. The six myths are:

  • Myth #1: Electric vehicles are worse for the climate than gasoline cars because of the power plant emissions.
  • Myth #2: Electric vehicles don’t have enough range to handle daily travel demands.
  • Myth #3: Electric vehicles only come as sedans.
  • Myth #4: There is nowhere to charge.
  • Myth #5: Electric vehicles are worse for the climate than gasoline cars because of battery manufacturing.
  • Myth #6: Electric vehicles are not as safe as comparable gasoline vehicles.

Emissions, Environment

The Infrastructure Carbon Estimator Version 2.1 is a spreadsheet tool that estimates the lifecycle energy and greenhouse gas emissions from the construction and maintenance of transportation facilities based on national emissions and energy use factors for materials and construction. Version 2.1 of the tool was developed through FHWA Transportation Pooled Fund TPF-5(362), led by the Minnesota Department of Transportation.

Emissions, Environment

AASHTO and FHWA explore greenhouse gas (GHG) reduction techniques, GHG measures and target-setting, and environmental policies. The webinar includes an introduction to the recent Notice of Proposed Rulemaking (NPRM) for state DOTs and MPOs to measure and reduce their GHG emissions. Representatives from Minnesota DOT, Colorado DOT, and District DOT share their agency's efforts in tracking and reducing emissions. The webinar closes with a presentation from McVoy Associates about their recently published NCHRP guide titled "Reducing Greenhouse Gas Emissions: A Guide for State DOTs".

For more information on the 2022 GHG NPRM, check out the GHG resource collection.

Emissions, Environment

This WebResource describes methods State DOTs may implement to assess and reduce their GHG emissions. The resource includes self-assessment tools, an overview of climate change issues, a framework for addressing GHG emissions, and numerous resources and links. The report organizes around nine functional areas of the agency, with cross-cutting topics to pull it all together. Through the discussions, tools, and resources in each section, the report provides support for reducing emissions across all stages of a project, from policy and planning to construction and maintenance. It also reviews stakeholder communication, partnerships with other agencies, and federal or state requirements. Readers may use this guide and its flexible presentation for addressing specific areas within an agency or to adopt an agency-wide approach.
