NYC Building Decarbonization Advisory
Local Law 97 sets annual carbon limits for most NYC buildings over 25,000 square feet, with stricter limits beginning in 2030. We help owners understand their exposure, plan emission reductions, and manage the capital projects that follow.
How We Help
We work across compliance analysis, capital planning, and project delivery, so owners have one advisor who sees how the pieces fit together.
LL97 sets carbon limits that tighten in 2030 and 2035, with penalties of $268 per metric ton of CO₂e above the limit. We analyze the building's energy data, quantify its exposure in each period, and identify cost-effective ways to reduce emissions.
See How It Works →Boiler replacements, electrification, and HVAC upgrades are significant capital commitments. We represent the owner through design and construction by coordinating the project team, reviewing scope, and confirming the completed work meets the project's performance goals.
See How It Works →From planning through procurement and construction, we manage schedule, budget, and reporting for energy upgrade projects and keep ownership informed at each stage.
See How It Works →Our Approach
We are compensated by our clients rather than by contractors or equipment suppliers. Our recommendations are based on the building's performance and the owner's financial objectives.
Recommendations are based on the building's systems, operating data, and compliance history.
We do not accept referral fees or commissions from contractors or equipment suppliers.
We follow LL97, LL87, LL88, and related NYSERDA and Con Edison programs, and explain how changes affect each building.
We help prioritize the investments that reduce LL97 exposure most per dollar spent.
