Vehicle Repair versus Replacement

09/06/2026

FAAS is pleased to share a new scientific publication developed on our initiative and published in the academic journal Transportation Engineering. The study was conducted by Politecnico di Torino, drawing on expertise and industry input from FAAS members.

As the automotive sector works towards reducing its environmental footprint, consumers and policymakers increasingly face an important question: is it more sustainable to repair and continue using an existing vehicle, or to replace it with a new one?

This research provides a comprehensive, evidence-based answer. Using a cradle-to-grave Life Cycle Assessment (LCA) approach, the study evaluates the environmental impacts associated with vehicle production, use, maintenance, repair, and end-of-life treatment. It enables users to better understand the true emissions implications of repair-versus-replace decisions across a wide range of real-world scenarios.

Key findings and innovations:

  • Comprehensive cradle-to-grave assessment, including use, maintenance, repair, and end-of-life emissions.
  • Analysis of multiple user-specific scenarios based on mileage, powertrain, fuel type, and geographic location.
  • Introduction of a novel methodology to allocate production impacts for second-hand vehicles.
  • Evaluation of the sustainability implications of consumer choices across diverse vehicle use cases.

The results demonstrate that extending the life of a vehicle through repair and maintenance is, in many scenarios, the more sustainable choice. By avoiding or delaying the environmental impacts associated with manufacturing a new vehicle, repair can significantly reduce overall lifecycle emissions.

The study provides valuable insights for consumers, industry stakeholders, and policymakers seeking to make informed decisions that support both mobility needs and environmental objectives. It also reinforces the important role of the automotive aftermarket in enabling a more resource-efficient mobility ecosystem.
