Private companies do not file with the SEC, so the full list of tenants is longer, and a company can also report a building it owns.

611 Fifth Avenue's 2024 Local Law 84 benchmarking filing got no ENERGY STAR score (a campus of several buildings cannot get a score), and Local Law 33 letter grades come from that score, so the filing does not yield an A to D grade. Its site energy use came to 80.3 kBtu per square foot, 43% above the national median of 56.3 for a similar property. Its greenhouse gas emissions were about 7,907 metric tons of CO2e (7.58 kg per square foot).

At its 2024 energy use, 611 Fifth Avenue comes to about 5,727 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 7,906 tons for 2024 to 2029 (72% of the limit), so it would owe no penalty. From 2030 the limit drops to 2,430 tons and the same energy use counts as about 3,606 tons, about 1,177 tons over, or an estimated $315,000 a year unless the building cuts its emissions. This is an estimate from the owner's 2024 benchmarking filing using the coefficients and per-use limits in the law and the Department of Buildings rule, at $268 per ton over. It is not the building's Local Law 97 report, which can count credits and deductions this estimate cannot.

A permit is approval to do the work; it does not say who the work is for or whether it is finished.
