Projects: Drawdown: Solutions to Promote Carbon Neutrality

Drawdown Georgia Phase One

2019-20: Selecting High Impact GA Solutions

1. Overview

2. Technical Review of 75 possible solutions for Georgia

The Academic Research team presented the findings of the carbon sinks and Mt CO2 reductions that are technically feasible to reach achieve a net zero GHG footprint and sell excess credits into carbon offset markets.

The Drawdown Georgia project was spotlighted in a half-day of activities at the August 6, 2020, Southface Institute’s Greenprints Conference. The project was introduced by John Lanier (Ray C. Anderson Foundation) and Daniel Rochberg (Emory University), then described in some detail by Marilyn Brown (Georgia Tech). Five high-profile Drawdown Georgia solutions were then introduced: Rooftop Solar (Marilyn Brown), Demand Response (Matt Cox), Composting (Sudhagar Mani), Retrofitting (Shane Totten), and Electric Vehicles (Rich Simmons). Before breaking into discussion sessions, Michael Oxman (Georgia Tech) described the Beyond Carbon considerations. The break-out discussions were synthesized in Miro Boards – characterizing Accelerators, Barriers, Beyond Carbon, and Promising Approaches. The participants offered lots of ideas and insights, which was a key goal of the event.

This working paper (on left) describes the first phase of our research, involving a fact-based assessment of Project Drawdown's solutions, to identify those that could significantly reduce Georgia’s carbon footprint by 2030.  The Appendix (on right) includes logic diagrams, info sheets, and references describing 75 individual solutions. Below is a quick reference of the 20 high impact solutions, organized by sector, which are retained for further research into costs and benefits required for carbon drawdown.
