Local Law 97 emissions limit
At its 2024 energy use, 511 Broadway comes to about 849 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 1,323 tons for 2024 to 2029 (64% of the limit), so it would owe no penalty. From 2030 the limit drops to 420 tons and the same energy use counts as about 495 tons, about 74 tons over, or an estimated $20,000 a year unless the building cuts its emissions.
