End-point method carries lower statistical uncertainty as it go through the whole cause-effect chain.

To explain the complicated LCA results to a non-engineer, it is easier to use end-point method as it has less categories to consider.

An endpoint method looks at environmental impact at the end of this cause-effect chain. (e.g. human health, ecosystem quality, and resource depletion).

Comparing to the End-point method, mid-point method can generally reveal more details along the cause-effect chain.

A midpoint method looks at the impact earlier along the cause-effect chain before the endpoint is reached.
