New York Local Law of 2019 – All About LL97

The New York City Council passed the historically significant Climate Mobilization Act, also known as Local Law 97, in 2019 to reduce greenhouse gas emissions across the city. 

The law places stringent caps on carbon dioxide output for many buildings based on their size – a major step towards mitigating climate change.

Local Law 97 ensures that individuals and businesses alike can be held accountable with regard to their emissions. 

With annual reports, NYC not only has an eye on compliance but also the potential of financial repercussions for those who fail to uphold standards—a strong reminder that being green is both a responsibility and a privilege!


How Does Local Law 97 Affect Condominiums and Cooperatives

Condominiums and cooperatives can take action to comply with Local Law 97. These steps will all help reduce emissions from buildings across New York City by:

  • Installing energy-efficient windows and insulation.
  • Upgrading lighting systems.
  • Making changes to the building’s envelope for improved efficiency performance.
  • Purchasing carbon offset credits.
  • Investing in renewable energy projects.

Condominiums and cooperatives in NYC must comply with Local Law 97, which imposes strict emissions caps on buildings over 25,000 square feet. 

The law is part of an ambitious plan to reduce the city’s carbon footprint by 40% before 2030 and 80% prior to 2050 – a lofty goal that will require everyone’s cooperation!

Local Law 97 has presented varying circumstances for condominiums and cooperatives, depending on their size and age as well as the efficiency of current energy measures

Those structures with already low emissions may be able to comply relatively easily; however, those that are older or lack efficient practices could face costly challenges trying to meet this new law’s regulations.

Local Law 97 is a progressive step toward reducing New York City’s carbon footprint. 

For condominiums and cooperatives, while it may present some obstacles in the short term, there are long-term benefits. They can get such benefits by investing in energy efficiency initiatives such as renewable energy sources – ultimately resulting in cost reduction and enhanced sustainability success.



Complying with Local Law, 97 can be a challenging task, due to its stringent requirements and hefty fines if not adhered to. It requires adherence to various other laws in addition to this one, so the pathway is complex yet necessary for businesses across New York City.
