New York City has an ambitious goal: reaching carbon zero by 2050. But with nearly 70% of the city’s emissions coming from buildings, meeting that goal requires transformative action—and fast.

That’s where Local Law 97 comes in. Passed in 2019, LL97 imposes strict energy efficiency and greenhouse gas emission limits on most buildings over 25,000 square feet. Supporters see it as a critical step toward the city’s climate goals, but the law has sparked questions about feasibility, fairness, and enforcement, as well as pushback from property owners.

In this episode we’re joined by JP Flaherty, who leads sustainability strategy at Tishman Speyer. JP will help us unpack what Local Law 97 means for the future of New York City and whether it can deliver on the promise of a carbon-zero future.
