Consequential Life Cycle Assessment of the Production of Palm Kernel Expeller (PKE) Specifically used as Animal Feed

 

 

Even though the system boundary for CLCA > ALCA this does not entail that the emissions figures from a CLCA will be greater than from an ALCA  as the product investigated is credited with an emissions reduction due to its co-products substituting other carbon intensive products

 

Attributional LCA (ALCA) provides information about the impacts of the processes used to produce (and consume and dispose of) a product, but does not consider indirect effects arising from changes in the output of a product, whereas Consequential LCA (CLCA) provides information about the consequences of changes in the level of output (and consumption and disposal) of a product, including effects both inside and outside the life cycle of the product.

 

 

 

 

 

 

 

 

 

 

 

 

CLCA models the causal relationships originating from the decision to change the output of the product and therefore seeks to inform policy makers on the broader impacts of policies which are intended to change levels of production.
