The City of Atlanta Office of Sustainability selected the Global Protocol for Community-scaleÂ Greenhouse Gas Emission Inventories (GPC)1 as the framework for its annual citywideÂ greenhouse gas (GHG) reports. By selecting this protocol, the City of Atlanta is consistent withÂ international standards. The GPC level selected for the 2013 reports was BASIC. This levelÂ will serve as a baseline for more comprehensive reports in the future. This report includedÂ emissions from electricity and natural gas consumption, vehicles, city-owned landfills,Â municipal solid waste (MSW) generated inside the city but sent to landfills out of the cityÂ limits, and emissions from wastewater treatment plants (WWTP), the Metropolitan AtlantaÂ 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 equivalentÂ (MmTCO2e); 54% of these emissions were the result of electricity consumption, while on-roadÂ vehicles emitted 27%, and burning natural gas accounted for approximately 9% of the total.Â The emissions from municipal solid waste (MSW) sent to landfills out of the city limitsÂ generated 4% of the total emissions; wastewater treatment plants emitted 1%, MARTAÂ generated 2%, and the airport generated2% as well (excluding out-of-boundary aviation fuelÂ emissions, which are considered out of scope for BASIC level reporting).View PDF Document
