Background: Life Cycle Assessment (LCA) is a methodology that considers a vehicle’s entire life cycle, from material and vehicle production (manufacturing phase) throughits lifetime on the road (use phase) to the end-of-life disposal (end-of-life phase), as well as the life cycle of its fuel sources. Current regulations in discussion around the world are focused on measurement of tailpipe emissions only, which is a reflection of the use phase. However, it isnot just vehicle use that generates GHG emissions, but all of its life cycle stages. Emphasis on the use phase alone may have the unintended consequence of increasing GHG emissions during the vehicle life.
