Prognosis

Not enough signal yet

Not enough signal yet to read this bill's trajectory — we surface a likelihood only once there's real movement (stage, sponsorship, committee, or votes) to point to.

Based on stage, sponsorship breadth, committee status, recorded votes, and cross-state momentum — a description of the observable signals, not a prediction.

In plain language

The bill requires a study on the environmental impacts of data centers before any new construction can occur.

This legislation mandates that the Department of Environmental Protection (DEP) perform a study on the environmental effects of data center development. Construction of new data centers is prohibited until the study is completed.
