Key Findings

  • 01Replacing conventional gasoline or diesel trucks with electric trucks can reduce CO2-equivalent (CO2e) emissions by 50%–75% on a per-mile basis.
  • 02100% electrification of in-state Class 8 vehicles by 2040 could reduce annual CO2e emissions by nearly 30% (50 million metric tonnes per year).
02

Application

Design takeaway

Designers should focus on optimizing electric truck performance and charging infrastructure to maximize emission reduction benefits and economic viability.

How to apply

When designing or specifying commercial vehicles, evaluate the life cycle emissions and costs associated with electric alternatives compared to traditional internal combustion engines.

Project actions

  • 01When researching sustainable transport, consider the full life cycle of vehicles, not just their operation.
  • 02Investigate how different charging methods affect the environmental benefits of electric vehicles.
03

Method & Evidence

AimTo quantify the life cycle environmental impacts and costs of electrifying California's freight truck sector and estimate the abatement potential of CO2e emissions.
MethodLife Cycle Assessment (LCA) and Cost-Benefit Analysis
ProcedureA freight vehicle operations model was developed using representative vehicle location data. This model was integrated with life cycle emissions inventory, technology cost, and pollution health damage cost data to compare conventional gasoline/diesel trucks with electric heavy-duty vehicles across various freight vocations and duty cycles. The study explored the impacts of different charging strategies and vehicle duty cycles on energy, costs, and emissions from 2020 to 2040.
