New York City is setting an ambitious course for a greener future, and your building is at the heart of it. Local Law 97, a landmark piece of legislation, isn’t just another regulation; it’s a critical step towards decarbonizing our urban landscape. For building owners and managers, understanding and acting on LL97 isn’t just about compliance – it’s about securing the future value and sustainability of your property.
What is Local Law 97? Enacted as part of the Climate Mobilization Act, LL97 establishes carbon emission limits for most buildings larger than 25,000 gross square feet. The goal? To drastically cut greenhouse gas emissions from NYC’s buildings, which account for nearly 70% of the city’s carbon footprint, paving the way for a carbon-neutral city by 2050.
Are You Affected? If your building (or a combination of buildings on the same tax lot) exceeds 25,000 square feet, then yes, LL97 applies to you. This includes a vast array of commercial, residential, and mixed-use properties across the five boroughs.
The Clock is Ticking: Key Deadlines & Penalties The first compliance period began in 2024, with annual reports reflecting 2024 usage due by May 1, 2025. There’s a 60-day grace period, extending the deadline to June 30, 2025, for timely filing without penalty. If you need more time, you can apply for an extension by June 30, 2025, pushing the deadline to August 29, 2025. Further extensions to December 31, 2025 are also possible through this extension request.
Beware: The Cost of Inaction The penalties for exceeding your building’s emission limits are substantial: $268 per metric ton of CO2 equivalent over your limit. Failure to file required reports can also lead to significant fines. These aren’t just minor fees; they’re designed to incentivize serious action.
Your Path to a Greener, Compliant Building Compliance with LL97 involves more than just reporting. It requires a strategic approach to energy efficiency. Consider:
- Energy Efficiency Upgrades: Modernizing HVAC systems, improving insulation, upgrading to LED lighting, and optimizing building controls.
- Electrification: Transitioning from fossil fuel-based heating and hot water systems to electric alternatives like heat pumps.
- Renewable Energy: Exploring options for on-site renewable energy generation or purchasing renewable energy credits.
Don’t let LL97 become a burden. Turn it into an opportunity! By investing in energy efficiency now, you can reduce your operational costs, enhance tenant comfort, increase your property’s value, and contribute to a healthier environment.
