life cycle assessment

“Complete streets” is a design concept for primarily urban streets and intersections (existing and/or new) intended to encourage active transportation by bicyclists and pedestrians by making streets safer, convenient, and attractive for active transportation. This project seeks to provide insight into specific and different potential benefits of a given complete streets project.

This study identifies the current pathways for retired EV batteries in the United States and Canada and anticipates how the network might evolve in the future.

The research examines the socio-economic and environmental implications of second-hand electric vehicle (SH EV) trade between the US and Mexico.

Utilizing a regionally expanded life cycle assessment (LCA), the study models the lifecycle emissions of these vehicles, factoring in changes in grid mixes, vehicle usage patterns, and EOL processes between the two countries. The results aim to inform policies that balance environmental benefits with social equity in the regional EV transition.

This dataset uses system dynamics modeling to project future EV adoption and SH vehicle trade between the US and Mexico. Results show EVs will comprise nearly 50% of Mexico’s fleet and up to 99% of SH imports by 2050, and SH EV batteries disproportionately contribute to the stock of spent EV batteries.

The researchers assessed whether the LCA framework was useful in identifying whether a complete street delivered, or was likely to deliver, the intended performance and benefits, and the social and health conditions of the neighborhoods receiving the benefits.

Sidewalk infrastructure presence is a key indicator of pedestrian safety and walkability for neighborhoods in cities throughout the United States. This work refines prior sidewalk infrastructure network generation techniques, contributing new methods to identify sidewalk infrastructure presence.

Lithium-ion battery recycling can decrease life cycle environmental impacts of electric vehicles (EVs) and assist in securing domestic supply chains; however, the US has no policies for recycling of batteries at their end-of-life. This analysis calculates feasible RCSs for the US based on future sale projections, techno-economic assessment, life cycle assessment, and material flow analysis.

This study develops a framework and first order estimate of the greenhouse gas emissions from the build-out and maintenance and rehabilitation of global roadway infrastructure networks from 2020 to 2050.
