NYC Local Law 97


The NYC Climate Mobilization Act, Local Law 97 sets limits on carbon emissions of existing buildings over 25,000 sq. ft. with an overlying goal to reduce greenhouse gas emissions by 80% in 2050. These hard limits that take effect in 2024 will require building owners to comply or be faced with penalties and hefty fines.

This presentation will provide an overview of Local Law 97 and the implications to the New York City built environment. We’ll focus on which buildings are required to comply, how carbon emissions limits are calculated, and how to address both immediate and long-term strategies for comprehensive retrofits.

With tenant energy consumptions playing a large part in overall building energy usage, we’ll discuss proactive ways to tailor design elements for new incoming tenants as well as how to broach energy upgrades for existing tenants.
