title: Data from: Regionally expanded life cycle assessment

description: As EV adoption accelerates in the U.S., the flow of second-hand EVs to
 Mexico is expected to increase, raising concerns about environmental
 justice and the management of end-of-life (EOL) lithium-ion batteries
 (LIBs). 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.
description: This project utilized data from a range of authoritative sources,
 including OEM technical specifications, trade statistics, vehicle
 registration records, electricity generation data, and life cycle
 inventories from the Ecoinvent database. Key vehicle models were selected
 to represent different market segments and propulsion technologies,
 ensuring relevance to current market trends. The data was processed
 through a regionally expanded life cycle assessment (LCA), which modeled
 the environmental impacts of second-hand electric vehicle (EV) trade
 between the U.S. and Mexico. This included analyzing vehicle
 survivability, battery degradation, and energy efficiency. The resulting
 data informed the life cycle impact assessment, focusing on GHG emissions,
 human health, and ecosystem damage, providing insights into the
 environmental and social implications of this cross-border EV
 trade.

 [https://doi.org/10.5061/dryad.cvdncjtcm](https://doi.org/10.5061/dryad.cvdncjtcm) ## Description of the data and file structure The experimental efforts for this project focused on modeling the life cycle environmental impacts of EVs involved in second-hand trade between the U.S. and Mexico. The study used a regionally expanded LCA approach, integrating dynamic processes such as battery degradation, energy efficiency changes, and vehicle survivability over time. Data was collected to simulate various scenarios, including EVs remaining in their country of first sale versus those exported to Mexico. ### Files and variables #### File: Data\_Regionally\_Expanded\_LCA.xlsx ##### Includes: | Tab 1- Tables showing the lifecycle impact of difference vehicle scenarios by age, broken down by lifecycle process | | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Tab 2- Tables showing the lifecycle impacts of baseline scenario vehicles and their relative difference with respect to a vehicle that is exported/imported, by age of export  | | Tab 3- Tables showing the lifecycle impacts of vehicle scenarios by age of export, in absolute values | | Tab 4- Tables showing the evolution of the US electricity grid energy mix and a forecast to 2050.
