NYC Local Law 97 Carbon Penalty Estimator & Building Leads

Find the New York City buildings that face Local Law 97 carbon penalties. For every covered building (over 25,000 sq ft) the actor estimates annual emissions with the official LL97 coefficients, the building's emissions limit from its property uses, the excess over the limit and the estimated annual penalty ($268 per ton) for both the 2024-2029 and 2030-2034 periods.

FAQ

Is the penalty an official determination?

No. It is an estimate computed from the building's published LL84 benchmarking data using the emission factors in 1 RCNY §103-14 and the LL97 coefficients. Actual penalties depend on the owner's filed report, deductions and adjustments.

Which buildings are included?

Buildings over 25,000 sq ft with LL84 energy data. Buildings with no reported energy use are skipped because their emissions cannot be estimated.

Am I charged if a run fails or finds nothing?

No. You pay only for records actually delivered to your dataset. Failed or empty runs cost nothing.

Is there a free trial?

Yes. Free Apify plans can run every actor and receive up to 10 results per run to evaluate the data.

Where does the data come from?

From official public records and open-data disclosures published by the government programs named on this page. BuildingSignal cleans, normalizes and standardizes them into one consistent schema.

How fresh is the data?

Each run reads the current official publication, so you always get the latest data the program has released. Schedule the actor to track changes over time.

Can I use it with my CRM or BI tool?

Yes. Export to CSV/Excel/JSON, call it through the Apify API, or connect it with Make, Zapier, n8n or Google Sheets integrations.
