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 citywide 2012Â emissions report. By selecting this protocol, the City of Atlanta is consistent with internationalÂ standards. This is the first City of Atlanta GPC report and as such, the level selected wasÂ BASIC. This level will serve as a baseline for more comprehensive reports in the future. ThisÂ report included emissions from electricity and natural gas consumption, vehicles, city-ownedÂ landfills, municipal solid waste (MSW) generated inside the city but sent to landfills out of theÂ 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 2012, the City of Atlanta emitted approximately 8.9 Million metric tons of CO2 equivalentÂ (MmTCO2e). More than half of these emissions were the result of electricity consumption, on road vehicles emitted 28%, and burning natural gas accounted for approximately 10% of theÂ total. 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%, the airport 2%Â (excluding out-of-boundary aviation fuel emissions, which are considered out of scope forÂ BASIC level reporting), and MARTA generated 2% as well. The major user of electricity was the commercial sector with 64% of consumption, followed by the residential sector with 25%,Â and the industrial sector with 5%. MARTA and the airport combined, consumed 5% of theÂ electricity. The biggest consumer of natural gas was the industrial sector with 40%, followedÂ by the residential sector with 31%, the commercial sector with 24%, and MARTA with 5%.
The City of Atlanta, through the Mayor’s Office of Sustainability, is focusing its efforts onÂ increasing energy efficiency in commercial buildings through programs such as the AtlantaÂ Better Buildings Challenge, which goal is to reduce commercial buildings energy consumptionÂ by 20% in 2020, and the Advanced Commercial Buildings Initiative, which target is to reduceÂ energy consumption in small buildings (< 50,000 sqf). The City of Atlanta was also selected toÂ participate in the City Energy Project (CEP) along with other nine cities. The goal of the CEPÂ is to craft an integrated framework of policies and programs that will cut energy waste in large buildings. To reduce on-road vehicle emissions, the city is implementing programs through theÂ Power to Change initiative, including doubling the number of alternative fuel infrastructure byÂ 2015, doubling the miles of bicycle lanes/cycle tracks by 2016, and promoting programs suchÂ as state tax rebates for the purchasing of EV vehicles and other available rebates to install EVÂ charging stations. The City of Atlanta is also working on a new Climate Action Plan to beÂ more aggressive on emissions reductions.
Since this is the first GHG inventory following GPC, patterns of consumption and emissionÂ reductions, or any other deeper analysis of data, were left to future reports.View PDF Document
