Methodology

The framework selected for this Climate Action Plan (CAP) was based on the Statewide Energy Efficiency Collaborative (SEEC) template[1]. SEEC is an alliance to help cities reduce greenhouse gas emissions and save energy. SEEC is a collaboration effort among three nonprofit organizations and California’s four Investor-Owned Utilities.

Atlanta follows ICLEI’s Five Milestones for Climate Mitigation. This CAP document meets milestone three: Develop a local climate action plan.

Projections for the City of Atlanta GHG Emissions were estimated using SEEC projections adjusted by emissions factors provided by the Forecasting Sustainable Energy and Environment (ForeSEE)[2] tool. This tool is a spreadsheet cost-benefit model developed to inform policy dialogues regarding distributed energy policy options.

City of Atlanta GHG reduction targets were selected to be consistent with suggested national and international agencies, or proposed in federal legislation. Most local governments have a priority target of 15-25% below 2005 levels by 2020. Targets proposed via federal legislation have sought reductions of 17-20% below 2005 levels by 2020. Almost all sources recommend a reduction of 80% by 2050.

Estimated reductions for commercial and industrial buildings, and energy production, were calculated using ForeSEE.

Reductions for the residential sector were estimated using Georgia Tech’s version of the National Energy Modeling System (GT-NEMS)[3].

Waste and recycling reductions were estimated using projections of existing waste emissions and desired targets by 2020.

Water and wastewater reductions were estimated using existing consumption trends and projections in the Water Supply and Water Conservation Management Plan, 2009, by the Metropolitan North Georgia Water Planning District.

Transportation reduction strategies followed guidelines by the Federal Highway Administration[4]. Reductions in VMT emissions were calculated using Atlanta Regional Commission (ARC) historical data and 2020 projections. Food security reductions were estimates using data from Georgia Organics[5].
