NYC buildings over 25,000 sq ft must report energy usage annually. With LL97 carbon penalties now in effect, accurate benchmarking is more critical than ever. We help you stay compliant and avoid escalating fines.
LL84 benchmarking reports must be filed annually by May 1st
NYC has enacted comprehensive legislation requiring buildings to benchmark energy usage and reduce carbon emissions.
Benchmarking Law
Requires annual benchmarking of energy and water consumption for buildings over 25,000 sq ft. Data must be entered into EPA's Energy Star Portfolio Manager and submitted to the city by May 1st each year.
Carbon Emissions Law
Sets carbon emission limits for buildings over 25,000 sq ft, with penalties starting in 2024. Buildings exceeding limits face fines of $268 per metric ton of CO2 over the limit. Limits become stricter in 2030.
Understanding the financial impact of missing deadlines or exceeding emissions limits.
| Violation Type | Penalty | Frequency |
|---|---|---|
| LL84 Late Filing | $500/month (up to $5,000/year) | Per building, per year |
| LL84 Non-Filing | $2,500 - $5,000 | Per building, per year |
| LL84 False Reporting | $500 - $5,000 | Per occurrence |
| LL97 Emissions Exceedance | $268/metric ton CO2 over limit | Annual |
⚠️ Example: A 100,000 sq ft office building exceeding LL97 limits by 500 metric tons would face annual penalties of $134,000. These costs compound year over year as limits become stricter.
