Social Life Cycle Assessment (LCA)—the analysis of social impacts spanning the complete value chain of a product or process—has never been more important than it is today for understanding and correcting widespread social injustices. In an increasingly interdependent world, we need to think and analyze systematically. Social LCA helps us expose in systemic fashion the social consequences of the dominant global development paradigm and, in so doing, has a vital role to play in redirecting global change towards a Great Transition future.
