In New York City, carbon is now a line item.
Local Law 97 sets hard annual greenhouse gas emissions caps on most NYC buildings over 25,000 square feet, and buildings that exceed their cap pay a penalty for every ton over — every year. The limits tighten in 2030. The buildings that get ahead of this pay for the retrofit with the incentives; the ones that wait pay the fine.

Local Law 97 assigns each covered building an annual emissions limit based on its occupancy type and square footage. Buildings that report emissions above their limit owe a penalty calculated per metric ton of CO2 equivalent over the cap — assessed annually, not once. Reporting is required, and the compliance limits step down again in 2030, which means a building that clears its cap comfortably today may not in a few years.
The planning question is not whether to comply but how to pay for it. The same energy work that brings a building under its cap — lighting, HVAC, envelope, controls — is frequently the same work that generates federal tax incentives, including the 179D deduction. Sequenced correctly, the retrofit that eliminates the penalty is substantially funded by the incentives it produces. Sequenced badly, you pay for the retrofit and miss the incentives.
Worth a look if you hold NYC property.
- Own an NYC building over 25,000 sq ft
- Own two or more NYC buildings totaling over 50,000 sq ft
- Manage a covered building on behalf of an owner
- Hold NYC property in a portfolio managed from out of state
- Are planning an energy retrofit on a covered building
- Are unsure whether your building is currently over its cap
Out-of-state owners are the most exposed, simply because the law is easy to be unaware of from a thousand miles away. If you hold NYC property inside a broader real estate portfolio, the first step is finding out whether the building is covered and where it currently sits against its cap.
Compliance and incentives are the same project.
Know your exposure
The penalty is annual and recurring. Modeling the building against its cap tells you what doing nothing actually costs, year over year.
Fund the retrofit
The energy work that brings a building into compliance often generates 179D and other incentives — offsetting a meaningful share of the cost.
Plan for 2030
Limits tighten. A retrofit designed against today’s cap alone may need doing twice. One plan, sequenced against both thresholds.
We bring it to the table and manage it end to end.
Assess
We confirm whether the building is covered and model its current emissions against its assigned limit.
Quantify
Penalty exposure is calculated for the current period and projected against the tightened 2030 limits.
Plan
A compliance path is developed and aligned with the federal energy incentives the same work can generate.
Capture
The retrofit is executed and the incentives — 179D and others — are certified and claimed, coordinated with your CPA.
Compliance first, incentives second, both at once.
Buildings routinely do the retrofit and miss the incentive, because the energy work and the tax work happen in different rooms and nobody connects them. The certification requirements for 179D have to be built into the project from the beginning — not discovered after the contractor has demobilized. Getting both requires planning them as one project, which is exactly how we approach it. Same standard we bring to everything: optimize aggressively, but never past the line.

A short call is enough to tell whether your building is covered, what the exposure looks like, and what incentives the fix could generate.
