Nature-based Carbon Dioxide Removal (CDR) – Plausibility, Feasibility and Sustainability – Presented to the Natural Systems Technical Advisory Group, Austin Community Climate Plan Five-year Revision. This presentation discusses the plausibility, feasibility and sustainability of the major categories of natural systems based carbon sequestration, summarizes the academic literature on the quantity of sequestration available in critical time frames, and identifies that existing nature-based systems are significantly inadequate to meet the 1.5 C target without assistance from traditional pollution treatment strategies.
