New York City Citywide CLCPA Inventory (2005-2021)

To compare City and State emissions, the City worked with the State’s Department of Environmental Conservation to develop a version of the citywide inventory using CLCPA methods. This incorporates both out-of-city fugitive emissions associated with citywide energy sources and a 20-year GWP. A comparison of the City’s traditional GPC inventory and its new CLCPA inventory shows that CLCPA emissions estimates are 54% to 68% larger than GPC estimates.
