2013 Greenhouse Gase (GHG) Inventory January 14, 2015

Executive Summary

The City of Atlanta Office of Sustainability selected the Global Protocol for Community-scale Greenhouse Gas Emission Inventories (GPC)1 as the framework for its annual citywide greenhouse gas (GHG) reports. By selecting this protocol, the City of Atlanta is consistent with international standards. The GPC level selected for the 2013 reports was BASIC. This level will serve as a baseline for more comprehensive reports in the future. This report included emissions from electricity and natural gas consumption, vehicles, city-owned landfills, municipal solid waste (MSW) generated inside the city but sent to landfills out of the city limits, and emissions from wastewater treatment plants (WWTP), the Metropolitan Atlanta Rapid Transit Authority (MARTA), and the Hartsfield-Jackson Atlanta International Airport.

All these emitting sources are in compliance with the GPC protocol.

In 2013, the City of Atlanta emitted approximately 8.86 Million metric tons of CO2 equivalent (MmTCO2e); 54% of these emissions were the result of electricity consumption, while on-road vehicles emitted 27%, and burning natural gas accounted for approximately 9% of the total. The emissions from municipal solid waste (MSW) sent to landfills out of the city limits generated 4% of the total emissions; wastewater treatment plants emitted 1%, MARTA generated 2%, and the airport generated2% as well (excluding out-of-boundary aviation fuel emissions, which are considered out of scope for BASIC level reporting).
