# How Much Will My Building Be Charged for Emissions Under LL97?

[ Emiley Mallory ](https://blog.catalystpower.com/more-power-to-you/author/emiley-mallory) •  April 18, 2024

If you’ve been paying attention to New York City’s most recent energy efficiency efforts, you can see the impact of the transition to clean energy in the state’s legislation. New York’s latest building emissions law, Local Law 97 (LL97), designed to reduce greenhouse gas (GHG) emissions, has been making [headlines](https://www.crainsnewyork.com/crains-content-studio/nyc-building-industry-embraces-climate-revolution-2024) lately. We’ve also written extensively about [LL97 here on the blog](https://blog.catalystpower.com/hs-search-results?term=LL97&type=BLOG_POST&type=LISTING_PAGE) and how Catalyst Power solutions can help keep your business compliant! 

LL97, [the largest decarbonization initiative in New York](https://blog.catalystpower.com/more-power-to-you/faqs-about-local-law-97-compliance-in-new-york) (and likely beyond in the near future), requires most large buildings over 25,000 gross square feet to meet new carbon emissions limits as of 2024. This means the stakes are high for building owners—if your building is non-compliant, [your business could face fines of up to $268 per ton of CO2](https://news.bloomberglaw.com/environment-and-energy/nyc-buildings-complying-with-emissions-law-faster-than-expected). However, there's good news! Online tools and renewable energy resources ([like our recent informational blog about LL97 compliance](https://blog.catalystpower.com/more-power-to-you/4-practical-ways-to-comply-with-local-law-97)) are available now to help you prepare and avoid penalties. 

View [NYC Accelerator’s Building Energy Snapshot](https://accelerator.nyc/building-energy-snapshot). 

Hosting a Catalyst Power-owned and operated [Connected Microgrid ® solution](https://catalystpower.com/our-solutions/connected-microgrid/) on your property or partnering with us for a [free community solar subscription](https://catalystpower.com/our-solutions/community-solar/) are just a couple of ways to protect your business from future fines. You can also use [a NYC LL97 carbon emissions calculator](https://www.be-exchange.org/calculator/) created by the Building Energy Exchange. 

**When Do the Regulations Go into Effect?** 

If your building falls under the purview of LL97, it's crucial to understand that you are expected to meet your carbon reduction limits this year. With over 50,000 large buildings mandated to cut their GHG emissions by 40% by 2030, the time to start implementing energy-efficient options for your business is **now**. Below, you can download a PDF file with a reference list of all covered buildings subject to LL97. Just so you know, this is not a final list, and its properties are subject to change. Different building types will also have different rules.
