Local Law 97 - Carbon Emission Limit

Local Law 97(LL97), takeS effect until 2024, but decisions made today will have a dramatic impact on buildings’ ability to comply with the law. Given the law’s long-term capital planning(LINK TO CAPITAL PLANNING PAGE) required to comply with the law, building decision makers need to know now whether or not it covers their buildings, and what, if any, alternative compliance pathways are available to them. This also enables owners to align compliance with normal replacement or refinancing cycles.

This law sets emissions caps for buildings larger than 25,000 square feet, which will cut carbon emissions at least 40 percent by 2030 and over 80 percent by 2050 from the affected buildings.

By 2030, this law is projected to reduce New York City’s carbon emissions by 6 million tons, the equivalent of taking 1.3 million cars off the road. It will also create 26,700 green jobs and prevent 50 to 130 premature deaths and 150 hospital visits annually by 2030.

LL97 will improve air quality, protecting New Yorkers from harmful pollution linked to asthma, emphysema, and other health conditions.

Compliance Pathways: The most prominent and best option is implementing energy conservation measure requirements for certain buildings. If opting for the alternative compliance pathway, building owners are required to submit a report prepared by a retro-commissioning agent demonstrating that they have implemented the appropriate energy conservation measures outlined below.Other alternatives are:

  • Purchase greenhouse gas offsets, also known as carbon offsets, to deduct up to 10% of a given building’s emissions.
  • Greenhouse gas emissions trading. Although, this is not a guaranteed pathway in the near-term.

Buildings with emissions higher than prescribed limits, however, must ensure that certain energy conservation measures have been conducted where applicable. These measures include and are not limited to :

  • Upgrading lighting to comply with the standards for new systems set forth inthe New York City Energy Conservation Code and/or applicable standards referenced in such energy code on or prior to December 31, 2024
  • Insulating all pipes for heating and/or hot water.
  • Installing timers on exhaust fans.
  • Weatherizing and air sealing where appropriate, including windows and ductwork, with focus on whole-building insulation.
  • Adjusting temperature set points for heat and hot water to reflect appropriate space occupancy and facility requirements.
  • Installing individual temperature controls or insulated radiator enclosures with temperature controls on all radiators.
  • Insulating the steam system condensate tank or water tank.
  • Installing indoor and outdoor heating system sensors and boiler controls to allow for proper set-points.
  • Replacing or repairing all steam traps such that all are in working order.
  • Installing or upgrading steam system master venting at the ends of mains, large horizontal pipes, and tops of risers, vertical pipes branching off a main.
