The transition to electrified transportation is occurring across the United States at different rates due to vehicle model availability, charging infrastructure, government engagement, and other factors. The Midwest region has, so far, not been a leader in electric vehicle sales, but sales are increasing.

Significant greenhouse gas savings are possible by transitioning from first-generation, food-based biofuels to advanced alternative, non-food based fuels.

Although China has one of the most densely populated coastal areas on Earth and is home to some of the world’s busiest ports, it is not protected by an International Maritime Organization-designated Emission Control Area (ECA).

As India considers strategies for the rapid electrification of its new vehicle market, policy experiences from around the world offer a variety of feasible pathways and concrete examples that can be tailored to the Indian context.

A new study provides a detailed picture of the health impacts attributable to emissions from four transportation subsectors: on-road diesel vehicles, on-road non-diesel vehicles, shipping, and non-road mobile sources such as agricultural and construction equipment.

Remote sensing is one technique used to measure real-world NOx emissions in Europe. Remote sensing measurements conducted by the Canton of Zurich are unique in terms of how consistently they have been collected since 2000 and the steep road grade at the main remote sensing monitoring site.

This briefing paper reviews the benefit-cost estimate developed by the National Highway Traffic Safety Administration (NHTSA) and the U.S. Environmental Protection Agency (EPA) to justify the Trump administration's August 2018 proposal to roll back the U.S. light-duty vehicle efficiency standards for 2020–2025.

While the Dieselgate scandal raised awareness of defeat devices—software calibrations that manipulate pollutant emission controls when vehicles are in the real world—third-party evaluation remains difficult because these devices are embedded in sophisticated computer code.

In adopting zero-emission vehicle (ZEV) regulations, questions remain regarding how quickly electric vehicle costs are declining and the magnitude of consumer benefits compared to conventional vehicles. This paper analyzes these two questions in the context of Colorado’s potential adoption of a ZEV regulation.
