Abstract

Subnational entities are recognizing the need to systematically examine options for reducing their carbon footprints. However, few robust and comprehensive analyses are available that lay out how US states and regions can most effectively contribute. This paper describes an approach developed for Georgia—a state in the southeastern United States called “Drawdown Georgia”, our research involves (1) understanding Georgia’s baseline carbon footprint and trends, (2) identifying the universe of Georgia-specific carbon-reduction solutions that could be impactful by 2030, (3) estimating the greenhouse gas reduction potential of these high-impact 2030 solutions for Georgia, and (4) estimating associated costs and benefits while also considering how the solutions might impact societal priorities, such as economic development opportunities, public health, environmental benefits, and equity. We began by examining the global solutions identified by Project Drawdown. The resulting 20 high-impact 2030 solutions provide a strategy for reducing Georgia’s carbon footprint in the next decade using market-ready technologies and practices and including negative emission solutions. This paper describes our systematic and replicable process and ends with a discussion of its strengths, weaknesses, and planned future research.

  • In 2030, based on the GT-NEMS baseline forecast, CO2 emissions from energy consumption in Georgia are estimated to come 41% from electricity and 39% from transportation.

    “In 2030, based on the Georgia Tech–National Energy Modeling System (GT-NEMS)’s baseline forecast, CO2 emissions from energy consumption in Georgia are estimated to come 41% from electricity and 39% from transportation, making these two sectors key targets of carbon-reduction opportunity (32).”
  • Synergistic emissions occur when implementing one solution, such as large-scale solar, boosts the emissions reduction of another, as when EVs operate on lower-carbon electricity.

    “Synergistic emissions occur when the implementation of one solution (such as large-scale solar) boosts the emissions reduction of another, as occurs when EVs operate on lower-carbon electricity.”
  • Mid- and long-term solutions can be difficult to translate into large-scale options if today's choices make them more costly to develop in the future, an example of near-term solutions becoming barriers to alternative and potentially more transformative changes.

    “Such mid- and long-term solutions can be difficult to translate into large-scale options if today’s choices make them more costly to develop in the future—an example of near-term solutions becoming barriers to the deployment of alternative and potentially more transformative changes (32).”
  • Underpinning the analysis of all 20 solutions is a characterization of Georgia's current carbon footprint, created using traditional government and NGO data sources.

    “Underpinning the analysis of all 20 solutions is a characterization of Georgia’s current carbon footprint, which is created using traditional government and NGO data sources and is further described in ref. 32 (SI Appendix).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
