Local Law 97
Local Law 97 (LL97) is part of New York City’s Climate Mobilization Act, aimed at drastically reducing greenhouse gas (GHG) / COâ‚‚ emissions from buildings.
Enacted in 2019, LL97 sets strict carbon emissions limits for buildings over 25,000 square feet, with penalties for non-compliance starting in 2025. The law is one of the most ambitious building decarbonization regulations in the world and is designed to help NYC achieve its goal of reducing emissions and becoming fully carbon neutral by 2050.
The challenge – Traditional compliance methods such as heat pumps and direct electrification require expensive electrical upgrades, increased grid demand and tenant disruptions.
LL 97
Solution
Standard Carbon’s Carbon Bridge™ provides a better alternative by converting COâ‚‚ into renewable gas, allowing buildings to achieve full compliance without costly retrofits or tenant disruptions.
This ensures your building’s compliance Local Law 97 while generating sustainable energy on-site and reducing operational costs.
Our technology brings your COâ‚‚ emissions to zero from day one, putting you in full compliance even after 2050.

The Process
Key Benefits
Retrofit-Ready
The Carbon Bridge™ is purpose-built for retrofitting – integrating seamlessly into existing infrastructure with minimal disruption and ensures compatibility by fitting into tight spaces and adapting to diverse building layouts.
Flexible Design
The Carbon Bridge™ was engineered for simplicity and cost-effectiveness, using streamlined designs and minimal components making it easy to implement in small and large buildings alike.
Electrified
The smart energy management system in the Carbon Bridge™ decouples energy consumption from demand, allowing buildings to leverage cheap off-peak electricity, dramatically reducing energy costs while eliminating emissions.

Electrification
Electrification alone doesn’t ensure lower emissions—timing matters. Heat pumps run whenever heating is needed, even during peak hours when NYC’s grid relies on high-carbon gas plants.
Carbon Bridge™ avoids peak-hour emissions and costs by operating only when cleaner baseload power is available. Actual NYISO data* shows off-peak electricity has a 30% lower carbon index, making Carbon Bridge™ a smarter decarbonization strategy.
By leveraging time-of-use energy storage, Carbon Bridge™ cuts COâ‚‚ emissions and electricity costs, providing a cost-effective, LL97-compliant alternative to heat pumps.

Economics
EX. a 50,000 sq. ft. building exceeding LL97 limits could face $250k in annual fines, with even stricter penalties coming in 2030.
The Carbon Bridge™ not only eliminates these fines by capturing COâ‚‚. and converting it into renewable energy, it reduces both emissions and offsets utility expenses.
With a typical 5-7 year payback period, building owners can achieve perpetual savings while ensuring compliance through 2050 and beyond.
When factoring in the avoided penalties in this example, the payback period is shortened to less than 3 years.
A typical Air Source Heat Pump (ASHP) system for a similarly sized building can cost upwards of $5-10 Million and provides no tax credit benefits.
Penalty Abatement
Fines that your building is facing this year can be avoided with a good faith effort (GFE) extension filing before May 1. Think of it as an extension for your tax return.
​
A GFE extension eliminates fines and enables you to decarbonize your building.
