I am currently working on an LCA investigating emissions from battery and fuel cell fleet vehicles across the entire life cycle, taking into account emissions from the following stages:
<!--[if !supportLists]-->- <!--[endif]-->Vehicle Production
<!--[if !supportLists]-->- <!--[endif]-->Fuel Production
<!--[if !supportLists]-->- <!--[endif]-->Fuel Conditioning and Distribution
<!--[if !supportLists]-->- <!--[endif]-->Vehicle/Fuel Use
- Vehicle EOL
The vehicles operate in the fleet for 6 years, but are then replaced by newer vehicles. These replaced vehicles still operate just not in the fleet I am investigating. How do I calculate the emissions associated just for the 6 year use phase within the fleet? The vehicle production and EOL emissions should be shared across the entire vehicle life, so to assign the portion of emissions just to this 6 year use, how do I do this?
If I assume the vehicle have a lifetime of 20 years, can I do (6/20 x 100) = 30% and say 30% of the total vehicle production and EOL emissions are attributed to use in this fleet?
I'm new to LCA and would really appreciate any insight if people have covered this before.
Many thanks!
