Previous environmental-burden releases
CalEnviroScreen 4.0 based California release
This historical release used the CalEnviroScreen 4.0 Pollution Burden percentile. Its tract records, checksums, metadata, and signed verification bundle remain unchanged so earlier outputs can be reproduced. It is not a current public model.
Previous CalEnviroScreen-based Canopulse releases are preserved separately for reproducibility and are not used in current reports.
