Tech for Local Law 97

Climate-tech leaders supporting a groundbreaking plan to reduce emissions in NYC

  • Over 70 percent of New York's greenhouse gas emissions come from buildings.
  • NYC Local Law 97, passed in 2019, is the world’s most important city-level climate and jobs law. It requires large buildings - the bulk of NYC’s real estate square footage - to slash their greenhouse gas emissions.
  • The on-site energy efficiency upgrades that the law induces will create tens of thousands of jobs and drive massive capital investment for decades to come, plus lead to many health and quality of life improvements for everyday New Yorkers.
  • Unfortunately, the law itself is now at risk.

What is Local Law 97 and why is it important for climate action?

Local Law 97 requires most buildings over 25,000 square feet to meet new energy efficiency and greenhouse gas emissions limits by 2024, with stricter limits coming into effect in 2030. The goal is to reduce the emissions produced by the city's largest buildings 40 percent by 2030 and 80 percent by 2050.
Local Law 97 is a critical step in New York City's fight against climate change. The law will help to clean the air, improve public health, and create a more sustainable future for our city. It will also set a bold example for cities around the world.
Don’t take it from us though! This great post from our friends at NY Climate Tech offers an excellent primer, and even NYC’s city government website is emphatic about the benefits of Local Law 97. Want to go deeper? Urban Green Council has also done lots of great work digging into LL97’s nitty-gritty details.

Why is the law currently at risk?

The law is currently at risk due to two delaying strategies being pursued by the commercial real estate lobby:
  1. The first strategy aims to allow non-compliant buildings to delay penalties for years either outright or by filing a paperwork "plan/study" to reduce their pollution, despite having had sufficient time (over 4 years!) to prepare. Such a rule change could effectively gut the law by deferring emissions reductions indefinitely.
  1. The second strategy involves offsetting onsite combustion emissions by purchasing renewable energy certificates (RECs), which would allow owners to avoid reducing pollution from fossil fuel use in their buildings, even though emissions from on-site combustion constitute a majority of the emissions from NYC’s buildings and ~40% of the city’s total.
As draft rules for the law are about to be released, it is crucial for supporters of climate action, including the climate tech industry, to engage and advocate for strengthening the law rather than watering it down. This is a key turning point for climate policy and NYC’s climate leadership.

How can I take action?

Fill out our open letter to Mayor Eric Adams here, and then follow through on a handful of key action items. All told, it shouldn’t take you more than five minutes:
If you want to take take political action in person, join our friends at Climate Changemakers for their weekly hour of action Wednesdays 8pm in Brooklyn (Atlantic Barclays), who will be helping us with this action item in the coming weeks. They do all the legwork to setup . Just show up!
