This paper helps define just transitions, emphasizing the origins of the concept in the labor movement and in social and environmental justice. The paper includes a schematic of the approaches of various groups to just transitions, mapping the views of various stakeholders and broadly grouping them under four approaches: status quo maintenance, managerial reform, structural reform, and transformative reform.

The authors review the origins of the concept of just transitions in the U.S. labor movement in the 1970s and discuss how it spread in the 2000s, largely under the rubric of climate policy and with more support from UN agencies and the International Labor Organization (ILO). The authors also explore the evolution of the just transition concept through case studies of six countries: Brazil, Canada, Germany, Kenya, South Africa, and the United States.
