By rerouting labor, investment and innovation toward resource-efficient and emission-free endeavors, environmental policies (EPs) transform economies. Although their impacts on employment vary by sector, time horizon and location, there is growing agreement that well-designed EPs may increase net employment while enhancing job quality-as long as there are supplementary measures for mobility, skills and a fair transition. Conceptual approaches, measuring techniques, sector-specific and global evidence and case studies from both developed and emerging economies are all covered in this study. In addition to highlighting distributional consequences (such as gender and informality) and identifying research gaps pertaining to data, assessment and long-term dynamics, it suggests a policy design checklist that optimizes job creation and reduces displacement.
