Local Law 97

What is Local Law 97?
Local Law 97 (LL97) is a key component of the Climate Mobilization Act (CMA) of 2019, a suite of legislation passed in New York City. It’s overseen by the New York City Department of Buildings, specifically their Bureau of Sustainability and the Local Law 97 Advisory Board.

The law focuses on improving energy efficiency and reducing greenhouse gas (GHG) emissions from large commercial buildings. To avoid penalties, these buildings must keep their carbon emissions under the established limit each year.

NYC’s LL97 applies to you if you own:

  • Buildings over 25,000 square feet in size
  • Two or more buildings on the same tax lot with a combined size exceeding 50,000 square feet
  • Emission limits are calculated based on the square footage of your building and the emission factor (MT
  • CO2e/sqft) associated with the given property type.
  • The emission limits for each compliance period gradually lowers, meaning it becomes progressively stricter. Additionally, the limits vary depending on the type of property you have.
  • Implications for building owners

Implications for building owners

  • If your property exceeds the building emissions limit, the penalty is $268 for every metric ton of carbon dioxide equivalent over the limit.
  • Failure to file the compliance report is $0.50/square feet, for each month you fail to report.
  • Submitting a report with false statements carries an additional $500,000 fine.
