The circular economy has gone mainstream as a goal in the transitions toward a more sustainable society. Often, however, laws that promote a circular economy remain vague or narrowly focused on resource efficiency, obscuring the fact that they have multiple environmental effects and can lead to environmental trade offs. This Article examines how to properly frame circular economy laws for sustainability, focusing on product-service systems generally and the case of car sharing in particular.

In February 2022, the Intergovernmental Panel on Climate Change (IPCC) promulgated climate-resilient development (CRD), which combines adaptation and mitigation as a principal strategy for managing climate change. This Article discusses local land use law in the context of CRD and provides a methodology for identifying and evaluating strategies that address the global climate crisis at the local level. Local governments have the power to integrate land use strategies that include CRD components, and the IPCC identified these strategies as effective tools for implementing CRD.
