Local Law 97
Local Law 97 is a landmark New York City Council statute passed during the 2019 New York City mayoral election cycle to reduce greenhouse gas emissions from large buildings in New York City. It establishes building-level carbon intensity limits tied to the New York State Climate Leadership and Community Protection Act, the Paris Agreement, and the Green New Deal discourse, and it integrates regulatory tools used by the New York City Mayor's Office of Climate and Environmental Justice, the New York City Department of Buildings, and the New York City Mayor's Office of Buildings to transform urban real estate portfolios held by institutions such as Related Companies, Silverstein Properties, Vornado Realty Trust, Brookfield Properties, and municipal actors including the Metropolitan Transportation Authority.
Local Law 97 emerged amid advocacy from groups including Natural Resources Defense Council, New York League of Conservation Voters, Sierra Club, WE ACT for Environmental Justice, and Greenpeace USA. The law was debated alongside legislative efforts like Local Law 92 of 2019, Local Law 94 of 2019, and the NYC Climate Mobilization Act, reflecting policy frameworks from the New York State Energy Research and Development Authority and guidance from the Intergovernmental Panel on Climate Change. Key political figures in its passage included Mayor Bill de Blasio, members of the New York City Council, and corporate stakeholders represented by organizations such as the Real Estate Board of New York and the Building Owners and Managers Association of Greater New York. The legislative history intersects with federal policy dialogues involving the Environmental Protection Agency and state court decisions influenced by precedents from the New York Court of Appeals.
The statute applies to buildings over 25,000 square feet, affecting portfolios owned by The Durst Organization, Hines Interests Limited Partnership, Tishman Speyer, SL Green Realty, and public entities including the New York City Housing Authority and City University of New York campuses. It sets carbon intensity limits in kilograms of CO2e per square foot per year with phased targets for 2024–2029 and more stringent caps for 2030–2034, aligning with trajectories advocated by Bill McKibben, Christiana Figueres, and reports from the International Energy Agency. The law differentiates by occupancy type—residential, office, retail, hotel—and references energy generation contexts such as the Indian Point Energy Center retirement and the regional New York Independent System Operator grid mix shifts influenced by Consolidated Edison operations and National Grid plc activities.
Enforcement mechanisms involve annual emissions limits, with monetary penalties calculated per metric ton of CO2e for noncompliance; fines are administered by the New York City Department of Finance pursuant to adjudication practices similar to those used by the New York City Office of Administrative Trials and Hearings. Building owners may pursue retrofits, on-site renewable installations, and purchases of verified renewable energy certificates sourced from projects like Iberdrola Renewables and Brookfield Renewable Partners. Financial incentives and programs from NYPA, NYSERDA, and federal initiatives under the Inflation Reduction Act of 2022 can be used to offset compliance costs. Market mechanisms and trading proposals echo models from the Regional Greenhouse Gas Initiative and compliance frameworks used by the California Cap-and-Trade Program.
Owners must submit annual greenhouse gas emissions reports, energy use data, and benchmarking consistent with protocols from the U.S. Department of Energy, the ENERGY STAR Portfolio Manager administered by the Environmental Protection Agency, and verification standards used by third-party firms such as Deloitte, PwC, and ERM. The law mandates measurement of onsite combustion, purchased electricity from Con Edison, steam from Consolidated Edison Steam Company, and fugitive emissions where applicable, with compliance documentation often prepared by engineering firms including Arup, AECOM, and WSP Global.
Anticipated impacts include accelerated retrofits by owners like Empire State Realty Trust and institutional investors such as Blackstone, Brookfield Asset Management, and Goldman Sachs-managed funds, influencing capitalization rates, asset valuations, and leasing dynamics in markets centered in Manhattan, Brooklyn, Queens, Bronx, and Staten Island. Architects and design firms—Skidmore, Owings & Merrill, SHoP Architects, Foster + Partners, Kohn Pedersen Fox—and engineering consultants predict shifts toward electrification, high-performance façades, and efficient HVAC systems from manufacturers like Carrier Global and Trane Technologies. Lenders and insurers including JPMorgan Chase, Bank of America, AIG, and Munich Re have adjusted underwriting models and risk assessments in response.
Critiques have been raised by trade groups such as the Real Estate Board of New York, labor organizations including the Building Trades Employers' Association, and municipal stakeholders like the New York City Department of Housing Preservation and Development about cost burdens, displacement risks, and technical feasibility. Lawsuits and administrative appeals have referenced state preemption doctrines litigated in courts including the New York Supreme Court (Appellate Division) and the United States District Court for the Southern District of New York. Subsequent rulemaking and revisions have involved technical advisory committees with experts from Columbia University, New York University, Pratt Institute, Cornell University, and consultative input from firms like Rudin Management Company.
The timeline phases initial limits for 2024–2029 and stricter limits beginning in 2030, with compliance cycles, reporting deadlines, and penalty assessments coordinated with agencies such as NYC Department of Buildings and NYC Mayor's Office of Climate and Environmental Justice. Future updates may reflect decarbonization trajectories in analyses by IPCC, International Energy Agency, and state policy shifts under New York Governor Kathy Hochul and federal climate initiatives influenced by the Biden administration. Ongoing monitoring by nonprofits like Urban Green Council and research from think tanks such as the Rockefeller Foundation and Brookings Institution will shape revisions, exemptions, and potential market-based compliance mechanisms.
