## Definition
**Software platforms, indices, or assessment frameworks that spatially integrate demographic, environmental, and health data to identify communities disproportionately burdened by environmental hazards**. Tools enable targeting of resources or regulations to vulnerable populations.
---
## General Context
Environmental justice screening tools (EJSCREEN, CalEnviroScreen, etc.) emerged from research documenting that marginalized communities bear disproportionate pollution burdens. Tools spatialize this knowledge, enabling policy targeting.
---
## Governance Context
See [[articles/climate-justice-meritocracy|How Reparative Justice Became Meritocracy, and Public Weather Data Became Private Risk Scores]] on how EJ screening tools transitioned from identifying vulnerable populations to creating climate meritocracy categories.
---
## Key Insight
Tools designed for resource allocation can become surveillance systems. A tool that identifies vulnerable communities for protection can be repurposed to identify populations for control.
