The Biden Administration's Justice40 initiative promises to allocate at least 40 percent of the benefits from federal investments in climate and clean energy to disadvantaged communities.In order to deliver on this promise, both the concept of "benefits" and "disadvantaged communities" need to be defined-otherwise, the promised distribution of benefits cannot be evaluated. While the Justice40 initiative is moving forward at the federal level, it is likely that over the next decade, U.S. states will follow the federal government's leadership in allocating benefits to disadvantaged communities. At the same time, U.S. states are experimenting with different approaches to environmental justice community definition and policy interventions.Environmental justice policy research, which has traditionally focused on analyzing how state characteristics are correlated with the existence of an environmental justice policy, is based on a conceptualization of justice that splits policies into procedural or substantive categories. There is little research that focuses on environmental justice policy at the U.S. state level and incorporates more complex theories of justice from a wide range of environmental justice theorists.
