New York's Two-Track Climate Reporting Regime: From Measurement To Mandatory Disclosure

A Shift from Climate Targets to Enforceable Data

While California has dominated headlines in the climate disclosure space, New York is quietly constructing a regulatory architecture that moves the state from a focus on climate ambition to enforceable compliance.

New York is building a greenhouse gas ("GHG") reporting framework that now operates on two distinct tracks: a facility- and supplier-based reporting rule (Part 253) that is already effective, and a separate corporate disclosure proposal that would materially expand the number of covered companies if enacted. The two tracks are easy to conflate because both focus on GHG data, but they differ significantly in legal status, scope, and immediate compliance impact.
