Watch our special webinar with the NYC Mayor’s Office of Climate and Environmental Justice (MOCEJ) unpacking NYC’s Greenhouse Gas Inventory. The Greenhouse Gas Inventory is critical for tracking progress on our decarbonization goals because it provides a detailed local accounting of energy use and emissions that can differ from regional or national estimates.
In this webinar, we covered how the City calculates emissions from the building sector, including how the carbon intensity of the grid impacts this calculation. We also discussed how the City tracks the sources of electricity that power NYC’s electric grid, including the new clean power set to flow into NYC over the next few years.

Key takeaways
- Tracking the GHG emissions tied to using electricity from NYC’s grid is key for understanding the emissions from buildings
- NYC’s grid currently relies heavily on fossil fuels, but this is set to change in the next few years as more clean power is brought into NYC
- The NYC Mayor’s Office of Climate and Environmental Justice collects and analyzes data from many different sources to create the city’s Greenhouse Gas inventories each year.
- NYC’s Greenhouse Gas inventories have been published for 20 years, which allows for in-depth historical tracking of the City’s progress on reducing energy and emissions.
