Buildings generate 70% of NYC’s greenhouse gas (GHG) emissions. We worked to pass the landmark Local Law 97 in 2019, which mandates a 40% reduction in GHG emissions from large buildings by 2030; and Local Law 154 (aka Intro 2317) in 2021, which bans gas hookups in new buildings. Given that Mayor Adams is supported by the real-estate lobby, we must make sure that these laws are implemented, which will also generate thousands of local jobs.

Hydrofluorocarbon refrigerants are a powerful greenhouse gas when they leak. We have been working at both local and federal levels to establish guidelines for life-cycle management of these gases and eventually phasing them out.

Transportation emits over 25% of NYC’s global heating gases, as well as creating significant respiratory health issues through pollution.

Today in NYC about 10,000 diesel-fueled school buses are routed through and parked in our most vulnerable communities. 350 NYC has pushed very hard to electrify the city’s school bus fleet. Electrification will improve air quality and health outcomes for children, communities on the bus routes, and drivers, while reducing global warming and creating a launchpad to transition other medium and heavy-duty vehicles to battery power. In 2021, we worked within the NYC Electric School Bus Coalition to successfully pass City Council Intro 0455. This law mandates that NYC will have 100% electric school buses by 2035.

Our other areas of interest include:

  • Taking our streets back from cars in favor of pedestrians, bike, and bus lanes,
  • Congestion Pricing, and
  • Electrifying MTA buses.

The Buildings and Transportation committee collaborates with environmental justice groups such as New York Communities for Change and Climate Works for All in order to ensure a just transition to a zero-carbon future.

We hope you will join us. We welcome you and as a group, we can do more.
