These types of graphs allow acquiring a more complete vision of a complex
system. They enhance reliability of conclusions in comparative LCA by showing
whether differences are significant or not in terms of sign and amplitude. Instead of
answering the question “Is a system better than another one in defined specific
cases?”, delta graphs and areas of relevance help LCA studies to answer a much
broader question: “In which range of situations is a system better than another
one?”. This is of great help to decision makers.
