Greenhouse Gas Emissions

This dataset represents the annual greenhouse gas emissions produced by the City of Boston from 2005 to 2021. The annual inventory is based on a combination of direct data and estimates for data that cannot be obtained directly. Data sources vary, and include City records, utility company reports, and information from state and federal agencies. Reporting is separated into community-wide and local government operations inventories. Because the data for these inventories is collected using separate protocols on separate timescales, the Local Government Operations Inventory should be considered to be overlapping, but not completely contained within the Citywide Inventory.

You can view the inventory report on the City's main website.

Note: We reviewed our community methodology and updated emissions data across the 2005-2021 period accordingly. Please contact environment@boston.gov if you would like to access past datasets or discuss the methodology.
